> The default imageType for PDFImageWriter.writeImage() is 8, which is TYPE_USHORT_565_RGB. I suggest to use TYPE_INT_RGB instead. The current default might create a poor user experience.
> I also suggest that the type and the resolution ("screen resolution or 96 if not detected") be added to the javadoc.
> Finally, the variable "imageType" is used with two different meanings in that file: once as a string for the format, once as int for the BufferedImage type.
