Managing Color With ColorSync


Video Card Gamma Storage Type

New in ColorSync 2.5

A video card gamma profile tag can store gamma data either as a formula or as a table of values. You use a storage type constant to specify which data storage type the tag uses.

IMPORTANT

If the video card uses a different format than the format you specify (for example, the card uses data in table format and you supply data in formula format), ColorSync will adapt the data you supply to match the format the card expects.

enum
{
    cmVideoCardGammaTableType = 0,
    cmVideoCardGammaFormulaType = 1,
};
