BitmapPainter

Cmn

BitmapPainter(
    image: ImageBitmap,
    srcOffset: IntOffset = IntOffset.Zero,
    srcSize: IntSize = IntSize(image.width, image.height)
)

Parameters

Parameters
`image: ImageBitmap`	The `ImageBitmap` to draw
`srcOffset: IntOffset = IntOffset.Zero`	Optional offset relative to `image` used to draw a subsection of the `ImageBitmap`. By default this uses the origin of `image`
`srcSize: IntSize = IntSize(image.width, image.height)`	Optional dimensions representing size of the subsection of `image` to draw Both the offset and size must have the following requirements: Left and top bounds must be greater than or equal to zero Source size must be greater than zero Source size must be less than or equal to the dimensions of `image`

image: ImageBitmap

The ImageBitmap to draw

srcOffset: IntOffset = IntOffset.Zero

Optional offset relative to image used to draw a subsection of the ImageBitmap. By default this uses the origin of image

srcSize: IntSize = IntSize(image.width, image.height)

Optional dimensions representing size of the subsection of image to draw Both the offset and size must have the following requirements:

Left and top bounds must be greater than or equal to zero
Source size must be greater than zero
Source size must be less than or equal to the dimensions of image
