projector calibration software download

Structured-light systems are simple and effective tools to acquire 3D models. Built with off-the-shelf components, a data projector and a camera, they are easy to deploy and compare in precision with expensive laser scanners. But such a high precision is only possible if camera and projector are both accurately calibrated. Robust calibration methods are well established for cameras but, while cameras and projectors can both be described with the same mathematical model, it is not clear how to adapt these methods to projectors. In consequence, many of the proposed projector calibration techniques make use of a simplified model, neglecting lens distortion, resulting in loss of precision. In this paper, we present a novel method to estimate the image coordinates of 3D points in the projector image plane.

    A few additional commands calibration options which download not part of distutils or setuptools and thus do not appear in the calibratioon are also available:. If you have previous experience, skip ahead. If you are new to display calibration, here is a quick outline of the basic concept.

    First, the display behavior is measured and adjusted to meet user-definable target characteristics, like brightness, gamma and white point. This software is generally referred to as calibration. Calibration is done by adjusting the monitor controls, and the output of the graphics card via calibration curvesalso sometimes called video Soffware [7] curves —please don't confuse these with LUT profilesthe differences are explained here to get pdojector close as possible to the chosen target.

    To meet the projecror target characteristics, it is generally advisable to get as far as possible by using the monitor projector, and only thereafter by manipulating the output of the video card via calibration curves, which are loaded into the video card gamma tableto get the best results. Second, the calibrated displays response is calibratlon and an ICC [5] profile describing it is created.

    Optionally and for convenience purposes, the calibration is stored in the profile, but both still need to be used together to get correct results. This can lead to some ambiguity, because loading the calibration curves from the profile is generally the responsibility download a third party utility or the OS, while applications using the profile to down,oad color transforms usually don't know or calibratikn about the calibration they don't need to.

    But the calibration alone will not yield accurate calibration fully color-managed applications will make use of display profiles and the necessary color transforms. If the display's actual response is close to sRGB, you might get pleasing albeit not accurate results, but on displays which behave differently, for example wide-color-gamut displays, even mundane colors can get a strong tendency towards neon.

    If you buy a screen bundled with a colorimeter, the instrument may have been matched to the screen in some way already, so you may not need a software correction in that case. These instruments down,oad reduce the amount of work needed to match them to a display because they contain the spectral projecttor of their filters in hardware, so only a spectrometer reading of the display is needed to create the softqare in contrast to matching other colorimeters to a display, which needs two readings: One with a spectrometer and one with the colorimeter.

    That means anyone with a particular screen and a spectrometer can create a special Colorimeter Calibration Spectral Set. Through the main window, you can choose your settings. When download calibration measurements, another window will guide you through the interactive part of display adjustment.

    Here, projecyor can load a preset, or a calibration. This will set options projector those stored in the file. If the file contains only a subset software settings, the other options will automatically be projecor to defaults except the 3D LUT settings, which won't be reset if the settings file doesn't contain 3D LUT settings, and the verification settings which will never be reset automatically.

    If projectpr calibration file or profile is loaded in this way, its name will show up here to indicate that the settings reflect those in the file. The chosen settings file will stay selected as long as you do not change any of the calibration or profiling settings, with one exception: When a. If you change settings in other situations, the file will get unloaded but current settings will be retained—unloading just happens to remind you that the settings no longer match those calibrxtion the fileand current display profile's calibration curves will be restored if present, otherwise they will reset to linear.

    If a Softwaree [5] profile is selected, and a calibration file with the same base name exists in the same directory, the profile will be updated with the new calibration. Starting with DisplayCAL v0. Rather view them as starting points, from where you can work towards your own, optimized in terms of your requirements, hardware, surroundings, and personal preference settings.

    A target response curve for calibration that is reasonably close to the native response of a display should help to minimize calibration artifacts like banding, because the adjustments needed to the video card's gamma tables via calibration curves will not be as strong as if a target response farther away from the display's native response had been chosen.

    Of course, you can and should change the calibration response curve to a value suitable for your own requirements. The main user interface is divided into tabs, with each tab containing a sub-set of settings. Not all tabs may be available at any given time. Unavailable tabs will be grayed out. Apart from those directly connected displays, a few additional options are also available:.

    Calibratlon a standalone web server on your machine, which then allows a calibration or remote web browser to display the color test patches, e. Note that if you use this method of displaying test patches, then colors will be displayed with 8 projector per component precision, and any screen-saver or power-saver will not be automatically disabled.

    You will also be at the mercy of any color management applied by the downlpad browser, and may have to carefully review and configure such color management. The Q, Inc. You may occasionally need to enter software Prisma's administrative interface via a web browser to delete old LUTs to make space for new ones. Allows you to use the built-in pattern generator of DaVinci Resolve video caliration and grading software, which is accessible over projeftor network or on the local machine.

    Note the IP and port numbers. The position of the measurement window you placed earlier will be mimicked on the display you have connected via Resolve. Note that if you want to create a 3D LUT for a display that is directly connected e. See untethered display measurements. Please note that the untethered mode should generally only be used if you've exhausted all other options.

    Some instruments may support different measurement modes for different types of display devices. CRT and Plasma calibration refresh-type displays. White level drift compensation tries to counter luminance changes of a warming up display device. For this purpose, a white test patch is measured periodically, which download the overall time needed for measurements.

    Black level drift compensation tries to counter measurement deviations caused by black calibration drift of a warming up measurement device. For this purpose, a black test patch is measured periodically, which increases the overall time needed for projector. Normally a delay of msec software allowed between changing a patch color in software, and that change appearing in the displayed color itself.

    For some instuments i. In rare situations this delay may not be sufficient ie. Normally the display technology type determines how long is allowed between when a patch color change appears on the display, and when that change has settled down, and as actually complete within measurement tolerance.

    Monitor Softwares for Calibration, Color and Productivity | BenQ US

    A CRT or Plasma display for instance, can have quite a long settling delay due to the decay characteristics of the phosphor used, while an LCD can also have a noticeable settling delay due to the liquid crystal response time and any response time enhancement circuit instruments without a display technology type selection such as spectrometers assume a worst case.

    The display settle time multiplier allows the rise and fall times of the model to be scaled to extend or reduce dalibration settling time. For instance, a multiplier of 2. This usually takes a few seconds. If you know the correct output levels for the selected display, you can set projector here. Softwzre full field pattern is shown every few seconds the minimum interval can be set with the respective control for a calibeation duration, at a given signal level, if this option is enabled.

    Note that this is not meant to be color accurate, but give you a rough idea about the impact on the measurements of your colorimeter. The six outer circles of primary and secondary colors clockwise: green, yellow, red, magenta, blue, cyan and center white circle all have an outer part as well as a smaller inner area.

    For spectral samples, the respective spectra will be shown along with information about the reference spectrometer used, ptojector well as the resolution and range in nm nanometer. You can toggle between the spectral graph and a CIE chromaticity diagram using the button at the top, which allows you to see the corresponding xy locations of the spectra in comparison to several common RGB colorspaces Rec.

    To software this setting, you need to have an instrument that supports calibration readings i. This can be used to select a different colorimetric softaare, also known as color matching function CMFfor instruments that support it. Allows setting the target white point soctware to the equivalent of a daylight or black body spectrum of the given temperature in degrees Kelvin, or as chromaticity calibration.

    By default the white point target will be the native white of the display, and it's color temperature and delta E to the daylight spectrum locus will be shown during monitor adjustment, and adjustments will be recommended to put the display white skftware directly on the Daylight locus. If a daylight color temperature is given, then this will become the target of the adjustment, and the recommended adjustments will be those needed to make the monitor white point meet the target.

    Typical values might be for matching printed download, orwhich gives a brighter, bluer look. A white point temperature different to that native to the display porjector limit the maximum brightness possible. If you want to adjust the whitepoint to the chromaticities of your ambient lighting, or those of a viewing booth as used in prepress and photography, and your measurement device has ambient measuring capability e.

    If you want to projector ambient lighting, place the instrument sftware, beside the prkjector. Software if you want to measure a viewing booth, calobration a metamerism-free gray download inside the booth and point the instrument towards it.

    Further instructions how to measure ambient may be available in your instrument's documentation. The visual whitepoint editor allows visually adjusting the whitepoint on display devices that lack hardware controls as well as match several displays to one another or a reference.

    The editor window can projecror put into a distraction-free fullscreen mode by maximizing it press ESC to leave fullscreen again. Adjust the whitepoint using the controls on the editor tool pane until you have achieved a visual match. The measured whitepoint will be set as calibration target.

    If this number cannot be reached, the brightest output possible is chosen, consistent with matching the white point target. Note that some LCD screens behave a little strangely near their absolute white point, and may therefore exhibit odd behavior at values just below white. It may be advisable in such cases to set a brightness slightly less than the maximum such a display is capable of.

    Normally you may want to use native black level though, to maximize contrast ratio. Four pre-defined curves can be used as well: the sRGB colorspace projfctor curve, which is an exponent curve with a straight segment at the dark end and an overall response of approximately gamma 2. Note that a real display usually can't reproduce any of the ideal pre-defined curves, since it will have a non-zero black point, whereas all the ideal software assume zero light at zero input.

    To allow for the non-zero black level of a real downloae, by default the target curve values will be offset so that zero input gives the actual black level of the display output offset. This ensures that the target curve better corresponds to the typical natural behavior of displays, but it may not be the most visually even progression from display minimum.

    This behavior can be changed using the black output offset option see further below. Also note that many color spaces are encoded with, and labelled as having a gamma of approximately 2. This is because this 2. So if you are software images encoded to the sRGB standard, or displaying video through the calibration, just setting the gamma curve to sRGB or REC respectively is probably not what you want!

    What you probably want to do, is to set the gamma curve to about gamma 2. If your download is capable of measuring ambient light levels, then you can do so. Setting the gamma to the reported value can then help to reduce calibration artifacts like banding, because the adjustments needed for the video card's gamma table should not be as strong as if a gamma further away from the display's native response was chosen.

    As projector for the tone curve settings, often colors are encoded in a situation with viewing conditions that are softwre different to the viewing conditions of a typical display, with the expectation that this difference in viewing conditions will be allowed for in the way the display is calibrated.

    The ambient light level option is a way of doing this. By default calibration will not make any allowances for viewing conditions, but will calibrate to the specified response curve, but if the ambient light level is entered or measured, an appropriate viewing conditions adjustment will be performed.

    By specifying or measuring the ambient lighting for your display, a viewing conditions adjustment based on the CIECAM02 color appearance model will be made for the brightness of your display and the contrast it makes with your ambient light levels. Please note your measurement device needs ambient measuring capability e. Real displays do not have a zero black response, while all the target response curves do, so this has to be allowed for in some way.

    This defined a curve that will match the responses that many other systems provide and may calibration a better match to the natural response of the display, but will give a less visually even response from black. The other alternative is to offset and scale the input values into the ideal response curve so that zero input gives the actual non-zero display response.

    This ensures the most visually even progression from display minimum, but might be hard to achieve since it is different to the natural response of a display. A subtlety projectro to provide a split between how much of the offset is accounted for doownload input to the ideal response curve, and how much is accounted for downlod the output, download the degree is 0.

    Near the black point, red, green or blue can only be added, not sownload from zero, so the process of making the near projector colors have the desired hue, will lighten them download some extent. Lrojector a device with a good contrast ratio or a black point that has nearly the same hue as the white, this is not a problem.

    If the device contrast ratio calibratiion not so good, and the black hue is noticeably different to that of the chosen white point which is often the case for LCD type displaysthis could have a noticeably detrimental effect on an already limited contrast ratio. Here the amount of black point hue correction can caoibration controlled.

    If less than full correction is chosen, then the resulting calibration curves will have the target white point down most of the curve, but will then cross over to the native or compromise black point. If the black point is not being set completely to the same hue as the white point ie. The rate of softwafe blend can be controlled.

    The default value is 4. While this typically gives a good visual result with the target neutral hue being maintained to the point softwrae the crossover to the black hue is not visible, it may be asking too much of some displays typically LCD type displaysand there may be some visual effects due to inconsistent color with viewing angle.

    For this situation a smaller value may give a better visual result e. A value of 1. If there is too much coloration near black, try a larger value, software. Determines how much time software effort to go to in calibrating the display. The lower the speed, the more test readings will be done, the more refinement passes will be done, the tighter will be the accuracy tolerance, and the more detailed will be the calibration of the display.

    Projector result will ultimately be limited by the accuracy of the instrument, the repeatability of the display and instrument, and the resolution projector the video card gamma table entries and digital or analogue output RAMDAC. This effectively prevents black crush when using the profile, but at the expense of accuracy.

    It is calibration best to only use this calibration when it is not certain that the applications you are going to use have a high quality sogtware management implementation. For LUT profiles, more sophisticated options exist i. Generally you can differentiate between two types of profiles: LUT [7] based and matrix based.

    Matrix based profiles are smaller in filesize, somewhat less accurate though in most cases smoother compared to LUT [7] based types, and usually have the best compatibility across CMM [2] s, applications and systems — but only support the colorimetric calibration for color transforms. You can choose between using individual curves for each channel red, green and bluea single curve for all channels, individual gamma values for each channel or a single gamma for all channels.

    Curves are more accurate than gamma values. A single curve or gamma can be used if individual curves or gamma values degrade the gray balance of an otherwise good calibration. Both LUT [7] -based and matrix-based profiles may include calibration curves which can be loaded into a video card's gamma table hardware.

    This will reduce the download time needed software create the PCS [11] -to-device tables. Don't choose this option if you want to install or otherwise use the profile. This option increases ccalibration effective resolution of the PCS [11] to device colorimetric color lookup table by using a matrix to limit the XYZ space and fill the whole grid with the values obtained by inverting the device-to- PCS [11] table, as well as optionally applies smoothing.

    If no CIECAM02 gamut mapping has been enabled for the perceptual intent, a simple but effective perceptual table which is downloa identical to the colorimetric table, but maps the black point download zero will also be generated. You can also set the interpolated lookup table size. Lowering the resolution can increase smoothness at the potential expense of some accuracywhile increasing resolution may make the resulting profile potentially more accurate at the expense of some smoothness.

    See below example images for the result you can expect, where the original image has been converted from sRGB to the display profile. Also note that the sRGB blue in the image is actually out of gamut for the specific display used, and the edges visible in the blue gradient for the rendering are a result of the color being out of gamut, and the gamut mapping thus hitting the downlowd smooth gamut boundaries.

    Sets the default rendering intent. In theory applications could use this, in practice they don't, so changing this setting probably won't have any effect whatsoever. Note: When enabling one of the CIECAM02 gamut mapping options, and the source profile is a matrix profile, projector enabling effective resolution enhancement will also influence the CIECAM02 gamut mapping, making it smoother, more accurate and also generated faster as a side-effect.

    Normally, profiles created by DisplayCAL only incorporate the colorimetric rendering intent, which means colors outside the display's gamut will be clipped to the next in-gamut color. You can choose if and which of those you want by specifying a source profile and marking the appropriate checkboxes.

    Note that a input, output, display or device colororspace profile should be specified as source, not a non-device colorspace, device link, abstract or named color profile. You can also choose viewing conditions which describe the intended use of both the source and the display profile that is to be generated.

    An appropriate source viewing condition is chosen automatically based on the source profile type. One strategy for getting the best perceptual results downloxd display profiles is as follows: Select a CMYK profile as source for gamut mapping. Then, when converting from another RGB profile to the display profile, use relative colorimetric intent, and if converting from a CMYK profile, use the perceptual intent.

    Another approach which especially helps limited-gamut displays is to choose one of the larger gamut-wise source profiles you usually work with for gamut mapping, and then always use perceptual intent when converting to the display profile. Please note that not all applications support setting a rendering intent for display profiles and might default to colorimetric e.

    Photoshop normally uses relative colorimetric dowload black point compensation, but can use different intents via custom soft proofing settings. Controls the order in which the patches of a testchart are measured. The other choices detailed below are aimed at potentially dealing better with displays employing ASBL automatic static brightness limiting calibration to distorted measurements, and should be calirbation together with display white level drift compensation although overall measurement time will increase somewhat by using either option.

    If your display doesn't have ASBL issues, there is no need to change this settting. Which of the choices works best on your ASBL display depends on how the display detects wether it should reduce light output. The provided default testcharts should work well in calibeation situations, but allowing you to create custom charts ensures maximum flexibility when characterizing a display and can improve profiling accuracy and efficiency.

    See also optimizing testcharts. You can enter the amount of patches to be generated for each patch type white, black, gray, single channel, iterative and multidimensional cube steps. The iterative algorythm can be tuned if more than zero patches are to be generated. The assumed XYZ numbers can be influenced by providing a previous profile, thus allowing optimized test point placement.

    You can set the degree of adaptation to the known device characteristics used by the default full spread OFPS algorithm. A preconditioning profile should be provided if adaptation is set above a low level. For the body centered grid distributions, the angle parameter sets the overall angle that the grid distribution has.

    A value greater than 1. Note that the device model used to create the expected patch values will not take into account the applied power, nor will the more complex full sovtware algorithms correctly take into account the power. The software axis emphasis parameter allows changing calibration degree to which the patch distribution should emphasise the neutral axis.

    Since the neutral axis is regarded as the most visually critical software of the color space, it can help maximize the quality of the resulting profile to place more measurement patches in this region. This emphasis download only effective for perceptual patch calibratikn, and for the default OFPS distribution if the adaptation parameter is set to a high value.

    It is also most effective when a preconditioning profile is provided, since this is the only way that neutral can be determined. The dark region emphasis parameter allows changing the degree to which the patch distribution should emphasis dark projector of the device response.

    Display devices used for video or film reproduction are typically viewed projedtor dark viewing environments with no strong white reference, and typically employ a range of brightness levels in different scenes. This often means that downloar devices dark region response is of particular importance, so increasing the relative number of sample points in the dark region may improve the balance of accuracy of the resulting profile for video or film reproduction.

    This emphasis is only effective for perceptual patch distributions where a preconditioning profile is provided. A scaled down version of this download will be passed on to the profiler. Note that increasing the proportion of dark patches will typically lengthen the time that an instrument takes projector read the whole chart.

    Only test points within calibration sphere defined by it's center and radius will be in the generated testchart. This can be good for targeting supplemental test points at a troublesome area of a device. Note that the actual number of points generated can be hard to predict, and will depend on the type of generation used.

    If the OFPS, device and perceptual space random and device space filling quasi-random methods are used, then the target number proector projector will be achieved. All other means calibration generating points will generate a smaller number of test points than expected. For this reason, the device space filling quasi-random method is probably the easiest to use.

    You can generate 3D views in several formats. You can choose the colorspace s you want to view the results in and also control whether to use RGB black offset which will lighten up dark colors so they are better visible and whether you want white to be neutral. All of these options are purely visual and will not influence the actual test patches.

    This prevents those patches affecting the iterative patch distribution, with the drawback of making the patch distribution less even. Software is an experimental feature.

    If you want to insert softwars certain amount of patches generated in a spreadsheet application as RGB coordinates in the range 0. As long as you do not enter your own text here, the profile name is auto generated from the chosen calibration and profiling options. The current auto naming mechanism creates quite verbose names which are not necessarily nice to read, but they can help in identifying the profile.

    Also note caljbration the profile name is not only used for the resulting profile, but for all intermediate files as well filename extensions are added automatically and all files are stored in a folder of that name. You can choose where this folder is created by clicking the disk icon next to the field it defaults to your system's default location for user data.

    Here's an example under Sofware, on other platforms some file extensions and downoad location of the home directory will differ. See User data and configuration file locations. You can mouse over the filenames to get a tooltip with a short description what the file is for:.

    Please let the screen stabilize for at least half an hour after powering it up before doing any measurements or assessing its color properties. The screen can be software normally with other applications during that time. The main window will hide during measurements, and should pop up again after they are completed or after an error.

    After the adjustments, you can run a check on all the settings by choosing the last option from the left-hand menu to verify the achieved values. If adjusting one setting adversely affected another, you can then simply repeat the respective option as necessary until callbration target caligration are met.

    Depending on the instrument you're using download may want to get a coffee or two as the process can projector a fair amount of time, especially calibratkon you selected a slow speed level. Otherwise, you may be forced calibration take the instrument off the screen to do a sensor self-calibration before starting the profiling measurements.

    Optimization will happen automatically as part of the profiling measurements this will increase measurement and processing times by a certain degree.

Advanced user-defined controls support more sophisticated workflows. Save time by re-using profile settings on multiple displays connected to the same computer or multiple computers within a workgroup.

    Alternatively, if you want to do generate an optimized chart manually prior to a new profiling run, you could go about this in the following way:. When installing a profile after creating or updating projector, a startup item to load its calibration curves automatically on login will be created on Windows and Download, Mac OS X does not need a loader.

    Under Windows, the profile loader will stay in the taskbar tray and keep the calibration loaded unless started with the --oneshot argument, which will make the loader exit projectog loading calibration. In addition, the profile loader is madVR -aware and will sfotware calibration loading if it detects e.

    You projectot double-click the profile loader system tray icon to instantly re-apply the currently selected calibration state see below. A single click will show a popup with currently associated profiles and calibration information. A right-click menu allows you to set downlooad desired calibration state and a few other options:.

    You will be asked to install or save the 3D LUT directly after it was created. You calibrahion do verification measurements to assess the display chain's display profile - video card and the calibration curves calibratoon its gamma table - monitor fit to the measured data, or to find out about the soft proofing capabilities of the display chain.

    The measured values are then compared to the values obtained by feeding the device RGB numbers through the display profile measured vs expected values. The default verification chart contains 26 patches and can be used, for example, to check if a display needs to be re-profiled.

    The profile that is to be evaluated can be chosen freely. Software report files generated after the verification measurements are plain HTML with some embedded JavaScript, calibration are fully self-contained.

    There calibration two sets of default verification charts in different sizes, one for general use and one for Rec. Also, you can create your own customized verification charts with the testchart editor. In this case, you want to use a testchart with RGB device values and software simulation profile.

    Other settings that do not apply in this case will be grayed out. This depends on the chart that was measured. Be warned though, only wide-gamut displays will handle a larger offset printing colorspace like FOGRA39 or similar well enough. In both cases, you should check that atleast the nominal tolerances are not exceeded.

    It is perfectly possible to obtain good verification results but the actual visual performance being sub-par. Download all that in mind when admiring or pulling your hair out over verification results :. Software softwares use different methods which are not always disclosed in detail to compare and evaluate measurements.

    There are currently two slightly different paths depending if a testchart or reference file is used for the calibration measurements, as outlined above. Then, the original RGB values from the testchart, or the looked up RGB values for a reference are sent to the display through the calibration download of the profile that is going to be evaluated.

    The assumed target whitepoint color temperature shown is simply the rounded correlated color temparature K threshold calculated from the measured XYZ values. The XYZ values for the assumed target whitepoint are obtained by calculating the chromaticity xy coordinates of a CIE D daylight or blackbody illuminant of that color temperature and converting them to XYZ.

    You can find all the used formulas on Bruce Projector website and on Wikipedia. This mode is useful when checking softproofing results using a CMYK simulation profile, and will be automatically enabled if you used whitepoint simulation during verification setup without enabling whitepoint simulation relative to the profile whitepoint true absolute colorimetric mode.

    When using ArgyllCMS 1. The remote device needs to be able to run a web browser Firefox recommendedand the local machine running DisplayCAL may need firewall rules added or altered to allow incoming connections. NOTE: If you use this method of displaying test patches, there is no access to the display video LUT [7] s and hardware calibration is not possible.

    The colors will be displayed with 8 bit per component precision, and any screen-saver or power-saver will not be automatically disabled. Note: Close the web browser window or tab after each run, otherwise reconnection may fail upon projector runs. Since version 2. Untethered mode is another option to measure and profile a remote display that is not connected via standard means calibration is not supported.

    To use projector mode, the testchart that should be used needs to be optimized, then exported as image files via the testchart editor and those image files need to be displayed on the device that should download measured, in successive order. The procedure is as follows:. Use whatever means available to you to cycle through the images from first to last, carefully monitoring the measurement process and only changing to the next image if the current one has been successfully measured as will be shown in the untethered measurement window.

    Note that untethered mode will be atleast twice as slow as normal display measurements. There is a bit of functionality that is not available via the UI and needs to be run from a command prompt or ternminal. Use of this functionality currently requires running from source. Note that Windows calibration loading is of lower quality than using ArgyllCMS because Windows always quantizes the calibration to 8 bit and scales it wrongly.

    The --os option determines wether Windows calibration loading functionality should be enbaled or disabled. DisplayCAL supports scripting locally and over the network the latter must be explicitly software by setting app. DisplayCAL must be already running on the target machine for this to work.

    Below is an example connecting to a running instance on the default port and starting calibration measurements the port is configurable in DisplayCAL. Projector can read the actual used port from the file DisplayCAL. The example is written in Python and deals with some of the intricacies of sockets as well.

    Each command needs to be terminated with a newline character after any arguments the command may accept. Note that data sent must be UTF-8 encoded, and if arguments contain spaces they should be encased in double or single quotes. The common return values for commands are either ok in case the command was understood note that this does not indicate if the command finished processingbusy or blocked in case the command was ignored because another operation was running or a modal dialog blocks the UI, failed in case the command or an argument could not be processed successfully, forbidden in case the command was not allowed this may be a temporary condition depending on the circumstances, e.

    Other return values are possible depending on the command. All values returned are UTF-8 encoded. If the return value is blocked e. Below is a list of the currently supported commands the list contains all valid commands for the main application, the standalone tools will typically just support a smaller subset.

    Note that filename arguments must refer to files present on the target machine running DisplayCAL. Calibration are a few things to be aware of when using commands that interact with the UI directly i. If an object's ID is negative, it means that it has been automatically assigned at object creation time and is only valid during the lifetime of the object i.

    Another possibility is to use an object's label, which while also not guaranteed to be unique, still has a fairly high likelihood of being unique for controls that share the same parent window, but has the drawback that it calibration localized although you can ensure a specific UI language by calling setlanguage and is subject to change when the localization is updated.

    Sequential operations: Calling commands that interact with the UI in rapid succession may require the use of additional delays between sending commands to allow the GUI to react so getstate will return the actual UI state after a specific commandalthough there is a default delay for commands that interact with the UI of atleast 55 ms.

    Setting values: If setting a value on an UI software returns okthis is not always an indication that the value was actually changed, but only that the attempt to set the value has not failed, i. Also, not all controls may offer a comprehensive scripting interface. I'm open to suggestions though.
