DrawPixelsBgra8

Draws one bounded BGRA8 snapshot from a compute-compatible int buffer. Each value carries one packed 32-bit pixel; source dimensions are 1..2048, destination dimensions are positive logical coordinates, and the buffer count must exactly equal sourceWidth*sourceHeight. This first bridge copies into the active Canvas provider for the draw; it is deliberately not a shared GPU-resource or zero-copy contract.

Draw 2D shapes, text, images, and composited interface content.

external DrawPixelsBgra8(buffer of int pixels, int sourceWidth, int sourceHeight, int x, int y, int width, int height) returns bool

Status: source-declared

Parameters

buffer of int pixels

Supply pixels as buffer of int.

int sourceWidth

Supply source width as int.

int sourceHeight

Supply source height as int.

int x

Supply x as int.

int y

Supply y as int.

int width

Supply width as int.

int height

Supply height as int.
