◆ Equals()
If both are null, we return true.
If one is null and the other is not, we return false. If both are non-null, we do a deeper compare.
◆ gammaCloseToSRGB()
| bool SkColorSpace::gammaCloseToSRGB |
( |
| ) |
const |
Returns true if the color space gamma is near enough to be approximated as sRGB.
◆ gammaIsLinear()
| bool SkColorSpace::gammaIsLinear |
( |
| ) |
const |
Returns true if the color space gamma is linear.
◆ gamutTransformTo()

◆ isNumericalTransferFn()
| bool SkColorSpace::isNumericalTransferFn |
( |
skcms_TransferFunction * |
fn | ) |
const |
Sets |fn| to the transfer function from this color space.
Returns true if the transfer function can be represented as coefficients to the standard ICC 7-parameter equation. Returns false otherwise (eg, PQ, HLG).
◆ isSRGB()
| bool SkColorSpace::isSRGB |
( |
| ) |
const |
Returns true if the color space is sRGB.
Returns false otherwise.
This allows a little bit of tolerance, given that we might see small numerical error in some cases: converting ICC fixed point to float, converting white point to D50, rounding decisions on transfer function and matrix.
This does not consider a 2.2f exponential transfer function to be sRGB. While these functions are similar (and it is sometimes useful to consider them together), this function checks for logical equality.
◆ Make()
◆ makeColorSpin()
Returns a color space with the same transfer function as this one, but with the primary colors rotated.
In other words, this produces a new color space that maps RGB to GBR (when applied to a source), and maps RGB to BRG (when applied to a destination).
This is used for testing, to construct color spaces that have severe and testable behavior.
◆ makeLinearGamma()
Returns a color space with the same gamut as this one, but with a linear gamma.
◆ MakeRGB()
| static sk_sp<SkColorSpace> SkColorSpace::MakeRGB |
( |
const skcms_TransferFunction & |

|
) |
| |
|
static |
Create an SkColorSpace from a transfer function and a row-major 3x3 transformation to XYZ.
◆ MakeSRGB()
Create the sRGB color space.
◆ makeSRGBGamma()
Returns a color space with the same gamut as this one, but with the sRGB transfer function.
◆ MakeSRGBLinear()
Colorspace with the sRGB primaries, but a linear (1.0) gamma.
◆ ref()
◆ refCntGreaterThan()
◆ serialize()
Returns a serialized representation of this color space.
◆ toProfile()
| void SkColorSpace::toProfile |
( |
skcms_ICCProfile * |
| ) |
const |
Convert this color space to an skcms ICC profile struct.
◆ toXYZD50()
| bool SkColorSpace::toXYZD50 |
( |
skcms_Matrix3x3 * |
toXYZD50 | ) |
const |
Returns true and sets |toXYZD50|.
◆ toXYZD50Hash()
| uint32_t SkColorSpace::toXYZD50Hash |
( |
| ) |
const |
|
inline |
Returns a hash of the gamut transformation to XYZ D50.
Allows for fast equality checking of gamuts, at the (very small) risk of collision.

◆ writeToMemory()
| size_t SkColorSpace::writeToMemory |
( |
void * |

const |
If |memory| is nullptr, returns the size required to serialize.
Otherwise, serializes into |memory| and returns the size.
