makeBufferedImageback to summary
private BufferedImage makeBufferedImage(Image img, Color bgColor, int type, int sx1, int sy1, int sx2, int sy2)

Return a non-accelerated BufferedImage of the requested type with the indicated subimage of the original image located at 0,0 in the new image. If a bgColor is supplied, composite the original image over that color with a SrcOver operation, otherwise make a SrcNoEa copy.

Returned BufferedImage is not accelerated for two reasons:

  • Types of the image and surface are predefined, because these types correspond to the TransformHelpers, which we know we have. And acceleration can change the type of the surface
  • Image will be used only once and acceleration caching wouldn't help
