New features:

• Support multiple monitors. It will pick the monitor where the mouse cursor is.

Other:

• Support Ubuntu >= 22.04

New features:

• Add a HSVTransform filter with saturation boost, hue shifting and quantization.
• New help window, shown by default on startup.
• Merge the daltonize filters into a single one with a persistent setting for the deficiency kind.

UX improvements:

• Fix the color pointer overlay with small images by moving it to the controls window.
• Fix the Shift key behavior when the controls window has the focus.
• Show the perceptual distance to the two closest color names.
• Calling the global pointer while an image is already open won't close it, so the output of filters can be inspected.
• Better support of Spaces

Bug fixes:

• Fix the HSV range display in the highlight similar pixels filter.
• Fix the HSV transforms, wrongly applied in linearRGB instead of sRGB.
• Fix the RGB to LMS conversion to use the Judd-Vos correction XYZ space. No significant perceptual change, but should be more correct.

Changes since 2.4rc1:

• Add a HSVTransform filter with saturation boost, hue shifting and quantization.

• Better support of Spaces on macOS.

Fixes:

• High-dpi monitors are now supported on Windows and Linux.
• Fixed the hard-to-read text background on bright colors.

macOS specific:

• Improved the font quality on retina displays.
• Help dialog to notify about Screen Recording permissions.

Changes:

• The tritanopia filter is now using the much more accurate Brettel, Viénot and Mollon 1997 algorithm.
• Added a severity slider for the simulation / daltonization modes.
• Added a menu entry + Ctrl-S to save the filtered image.

First cross-platform version of DaltonLens (macOS, Windows, Linux/X11).

Main changes:

• The UI has been reworked to add a separate controls window with more info, a menu, etc. This is also a way to avoid using ImGui viewports as they are still experimental on Linux.

• Fix the daltonize filters to use the proper math from Viénot, Brettel & Mollon 1999 adapted to sRGB. Also fixed the tritanopia projection along the way.

• New option to only simulate color vision deficiencies instead of a full daltonize

• The color pointer has been improved to be more compact and support the 'c' shortcut to copy the information to the clipboard

• The image window can now be freely resized.

• Significant refactoring under the hood to make it easier to add new filters and unit test them.

First cross-platform version of DaltonLens (macOS, Windows, Linux/X11).
