animator.skia.Pixmap

class animator.skia.Pixmap

Bases: pybind11_builtins.pybind11_object

Pixmap provides a utility to pair ImageInfo with pixels and row bytes. The buffer protocol is supported. It is possible to mount Pixmap as array:

array = np.array(pixmap, copy=False)

Or mount array as Pixmap with ImageInfo:

buffer = np.zeros((100, 100, 4), np.uint8)
array = skia.Pixmap(skia.ImageInfo.MakeN32Premul(100, 100), buffer)

__init__(*args, **kwargs)

Overloaded function.

1. __init__(self: animator.skia.Pixmap) -> None

2. __init__(self: animator.skia.Pixmap, info: animator.skia.ImageInfo, addr: Optional[buffer], rowBytes: int = 0) -> None

   Creates Pixmap from info width, height, AlphaType, and ColorType, and a buffer addr.

3. __init__(self: animator.skia.Pixmap, array: numpy.ndarray, colorType: animator.skia.ColorType = <ColorType.kRGBA_8888_ColorType: 4>, alphaType: animator.skia.AlphaType = <AlphaType.kUnpremul_AlphaType: 3>, colorSpace: animator.skia.ColorSpace = None) -> None

Creates Pixmap backed by numpy array.
