It is unclear what you want. "PDFRenderer don't be extended by other package" -
it can be extended. PageDrawerParameters cannot be extended, see the class
javadoc why. ImageType.toBufferedImageType() cannot be extended but there is no
reason it should be.
If you want to render on "exotic" image types, then first render on RGB or
ARGB and then draw this image on the graphics device of your destination image.
