YUVAPixmaps

class YUVAPixmaps

Helper to store Pixmap planes as described by a YUVAPixmapInfo. Can be responsible for allocating/freeing memory for pixmaps or use external memory.

Methods

`Allocate`	Allocate space for pixmaps' pixels in the `YUVAPixmaps`.
`FromData`	Use storage in `Data` as backing store for pixmaps' pixels.
`FromExternalMemory`	Use passed in memory as backing store for pixmaps' pixels.
`FromExternalPixmaps`	Wraps existing `Pixmap`.
`__init__`
`isValid`	Does have initialized pixmaps compatible with its `YUVAInfo`.
`numPlanes`	Number of pixmap planes or 0 if this `YUVAPixmaps` is invalid.
`plane`	Get the ith `Pixmap` plane.
`planes`	Access the `Pixmap` planes.
`yuvaInfo`

Methods

static YUVAPixmaps.Allocate(yuvaPixmapInfo: skia.YUVAPixmapInfo) → skia.YUVAPixmaps: Allocate space for pixmaps’ pixels in the YUVAPixmaps.

static YUVAPixmaps.FromData(yuvaPixmapInfo: skia.YUVAPixmapInfo, data: skia.Data) → skia.YUVAPixmaps: Use storage in Data as backing store for pixmaps’ pixels. Data is retained by the YUVAPixmaps.

static YUVAPixmaps.FromExternalMemory(yuvaPixmapInfo: skia.YUVAPixmapInfo, memory: typing_extensions.Buffer) → skia.YUVAPixmaps: Use passed in memory as backing store for pixmaps’ pixels. Caller must ensure memory remains allocated while pixmaps are in use. There must be at least YUVAPixmapInfo.computeTotalBytes() allocated starting at memory.

static YUVAPixmaps.FromExternalPixmaps(yuvaInfo: skia.YUVAInfo, pixmaps: collections.abc.Sequence[skia.Pixmap]) → skia.YUVAPixmaps: Wraps existing Pixmap. The YUVAPixmaps will have no ownership of the Pixmap’ pixel memory so the caller must ensure it remains valid. Will return an invalid YUVAPixmaps if the YUVAInfo isn’t compatible with the Pixmap array (number of planes, plane dimensions, sufficient color channels in planes, …).

YUVAPixmaps.__init__(self: skia.YUVAPixmaps) → None

YUVAPixmaps.isValid(self: skia.YUVAPixmaps) → bool: Does have initialized pixmaps compatible with its YUVAInfo.

YUVAPixmaps.numPlanes(self: skia.YUVAPixmaps) → int: Number of pixmap planes or 0 if this YUVAPixmaps is invalid.

YUVAPixmaps.plane(self: skia.YUVAPixmaps, i: SupportsInt | SupportsIndex) → skia.Pixmap: Get the ith Pixmap plane. Pixmap will be default initialized if i >= numPlanes or this YUVAPixmaps is invalid.

YUVAPixmaps.planes(self: skia.YUVAPixmaps) → Annotated[list[skia.Pixmap], 'FixedSize(4)']: Access the Pixmap planes. They are default initialized if this is not a valid YUVAPixmaps.

YUVAPixmaps.yuvaInfo(self: skia.YUVAPixmaps) → skia.YUVAInfo
