Display calibration and characterization.

dispcalGUIOverview

dispcalGUI is a graphical user interface for the display calibration and profiling tools of Argyll CMS, an open source color management system by Graeme Gill.

Calibrate and characterize your display devices using one of the many supported hardware sensors, with support for multi-display setups and a variety of available settings like customizable whitepoint, luminance, black level, and tone-response curve, as well as the option to create matrix and look-up-table ICC profiles, with optional gamut mapping.

Other features include:
  • Support of colorimeter correction for wide-gamut screens via correction matrices or calibration specral sample files (the latter only for specific colorimeters, i.e., i1 Display Pro, ColorMunki Display and Spyder 4).
  • Profile verification: Check the quality of profiles via measurements. Also supports custom CGATS files (e.g., FOGRA, GRACoL/IDEAlliance, SWOP) and using of reference profiles to obtain test values.
  • Test chart editor: Create charts with any amount of color patches, easy copy-and-paste from CGATS, CSV files (only tab-delimited) and spreadsheet applications.

NEW

Added:
  • "Auto" measurement mode for the ColorHug. This will automatically create a colorimeter correction with the reference based on EDID as part of the normal measurement process. This is a work-around for the red primary shift problem that some ColorHug users are experiencing (note that this will make ColorHug measurements closely match the gamut boundaries defined by the primaries and whitepoint from EDID). This mode should only be used as a last resort if no colorimeter correction with reference measurements from a spectrometer or other known accurate instrument can be obtained.
  • Auto-update functionality. Apply updates from within dispcalGUI under Mac OS X and Windows, or if using Zero Install.
Changed:
  • Improved Zero Install integration. Installation is now as simple as a standalone installation.
  • Switched "Smooth B2A tables" off and "Low quality B2A tables" back on for the madVR preset to save some time during profile generation.
  • The HTML-embedded X3D viewer will now by default try and load its components from the web, with a fallback to a locally cached copy (if available) and not anymore the other way around. This means generated HTML files will automatically use updated viewer components when an internet connection is available.
  • Choosing "Profile information" from the "File" menu will now always present a file dialog to pick a profile and no longer use the profile currently selected in the main window (this functionality is still available via the small blue "Info" button next to the settings dropdown).
  • Show profile information with right pane expanded by default.
  • Don't lock measurement mode for colorimeter corrections, instead set colorimeter correction to none if an incompatible measurement mode is selected.
  • Allow black point compensation if "low quality B2A tables" is enabled.
  • Windows: Limit profile name length so that the length of the path of the temporary directory plus the length of the profile name does not exceed 254 characters (which is the maximum useable length for Argyll CMS tools where an extension with a length of four characters is added automatically).
Fixed:
  • When using the ColorHug in "Factory" or "Raw" measurement mode in dispcalGUI (r1378 or later) with a colorimeter correction that was created with Argyll CMS 1.5 or later, the measurement mode was being locked to the wrong mode (a colorimeter correction created in "Factory" mode would lock to "Raw" and vice versa).
  • Transpareny rendering in the HTML-embedded X3D viewer: Transparency is now gamma-corrected.
  • Tone response curves plot: Removed the very slight interpolation offset error at zero input (around +0.5 RGB on a 0-255 scale for a synthetic 16-bit tone response curve following a gamma of 2.2 with no black offset) for tone response curves that have zero output at non-zero input.
  • Trying to open files with unicode characters in their filename or path in the standalone testchart editor, curve viewer, profile information, or VRML to X3D converter application from the commandline, via the desktop's "open with" functionality, or by assigning a supported filetype to be opened with the respective application failed (dragging and dropping the file onto the respective application window worked fine).
  • Correctly reflect in the GUI if black point compensation can be applied. Black point compensation is available for curves + matrix profiles and XYZLUT profiles with either "low quality B2A tables" or "smooth B2A tables" enabled.
  • Linux: Fixed a problem with unicode when querying colord for the current display profile (regression of r1832).
  • Windows: Report could not be saved after finishing display uniformity measurements due to the file dialog not receiving mouse clicks or keyboard input.
  • Windows: Work-around python issues with long pathnames (>= 260 characters).
