Member Function Documentation

bool SkICC::isNumericalTransferFn

(

SkColorSpaceTransferFn *

fn

)

const

If the transfer function can be represented as coefficients to the standard equation, returns true and sets |fn| to the proper values.

If not, returns false. This indicates one of the following: (1) The R, G, and B transfer functions are not the same. (2) The transfer function is represented as a table that we have not managed to match to a standard curve. (3) The ICC data is too complex to isolate a single transfer function.

static sk_sp<SkICC> SkICC::Make ( const void *  , size_t    )

static

Parse an ICC profile.

Returns nullptr if the data is not a valid ICC profile or if the profile input space is not RGB.

bool SkICC::toXYZD50

(

SkMatrix44 *

toXYZD50

)

const

If the gamut can be represented as transformation into XYZ D50, returns true and sets the proper values in |toXYZD50|.

If not, returns false. This indicates that the ICC data is too complex to isolate a simple gamut transformation.
