animator.skia.Bitmap

class animator.skia.Bitmap

Bases: pybind11_builtins.pybind11_object

Bitmap describes a two-dimensional raster pixel array.

Bitmap supports buffer protocol. It is possible to mount Bitmap as array:

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

Or mount array as Bitmap with ImageInfo:

buffer = np.zeros((100, 100, 4), np.uint8)
bitmap = skia.Bitmap()
bitmap.setInfo(skia.ImageInfo.MakeN32Premul(100, 100))
bitmap.setPixels(buffer)
