A graphical user interface (GUI) to check an existing jpg/png image for (possible) color constraints. The image will be converted to protanope vision, deuteranope vision, and a desaturated version (monochromatic vision). Allows a rapid check whether the colors used in the image show some constraints with respect to color deficiency or color blindness.
Used in cvd_emulator. Takes an image object and converts
the colors using deutan, protan,
tritan, desaturate functions. The image
will be written to disc as a PNG file.
