Custom colour profile handling on image conversion

PSD

• If the image is multilayered, we check the first layer to get the colour profiles and colourspace info. Then:
  • If a profile contains the word “GRACoL”, we apply the following profiles:
    • GRACoL2006_Coated1v2.icc
    • sRGB_IEC61966-2-1_black_scaled.icc
  • If a profile contains the word “Coated”, we apply the following profiles:
    • sRGB_IEC61966-2-1_black_scaled.icc
  • If the profile is empty and the colour space is CMYK, we apply the following profiles:
    • ISOcoated.icc
    • sRGB_IEC61966-2-1_black_scaled.icc
  • Otherwise, we use the provided colour profile.

AI, EPS

• When AI and EPS are RGB, and converted to "png", "gif", "tiff", "webp", we do not change the colour profile and use what is provided in the file.
• When AI and EPS is converted to “jpg”, we create an intermediate jpeg file with sRGB applied to source. Then the colourspace from advanced option is only applied to the final image if it is any colourspace other than `RGB`.
• When AI and EPS is CMYK and converted to "png", "gif", "tiff", "webp", we apply sRGB profile on the source file as these are web / digital formats which support transparency, that we can thus maintain in the output.
