GimpUi.Preview.prototype.draw_buffer

function draw_buffer(buffer: ByteArray, rowstride: Number(gint)): void {
    // Gjs wrapper for gimp_preview_draw_buffer()
}
  

Calls the GimpPreview::draw_buffer method. GimpPreview itself doesn't implement this method so the behaviour is determined by the derived class implementing this method.

Since 2.2

buffer

a pixel buffer the size of the preview

rowstride

the buffer's rowstride
