Function Documentation

◆ SkColorTypeBytesPerPixel()

SK_API int SkColorTypeBytesPerPixel ( SkColorType ct )

Returns the number of bytes required to store a pixel, including unused padding.

Returns zero if ct is kUnknown_SkColorType or invalid.

Returns: bytes per pixel

◆ SkColorTypeIsAlwaysOpaque()

SK_API bool SkColorTypeIsAlwaysOpaque ( SkColorType ct )

Returns true if SkColorType always decodes alpha to 1.0, making the pixel fully opaque.

If true, SkColorType does not reserve bits to encode alpha.

Returns: true if alpha is always set to 1.0

◆ SkColorTypeValidateAlphaType()

SK_API bool SkColorTypeValidateAlphaType	(	SkColorType	colorType,
		SkAlphaType	alphaType,
		SkAlphaType *	canonical = `nullptr`
	)

Returns true if canonical can be set to a valid SkAlphaType for colorType.

If there is more than one valid canonical SkAlphaType, set to alphaType, if valid. If true is returned and canonical is not nullptr, store valid SkAlphaType.

Returns false only if alphaType is kUnknown_SkAlphaType, color type is not kUnknown_SkColorType, and SkColorType is not always opaque. If false is returned, canonical is ignored.

Parameters

canonical storage for SkAlphaType

Returns: true if valid SkAlphaType can be associated with colorType
