BlitImage

data class BlitImage(val image: DrawImage, val source: IntRect, val destination: IntRect) : DrawCommand(source)

Copies an image source rectangle into a tree-coordinate destination rectangle.

The source is nonempty and contained in DrawCommand.BlitImage.image. The destination is nonempty and uses half-open tree coordinates. Backends execute this command in the supplied command order; core does not clip or sample it.

Throws

IllegalArgumentException
