             Summary: PDFImageWriter default BufferedImage type makes output looks bad
                 Key: PDFBOX-1839
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1839
             Project: PDFBox
          Issue Type: Bug
         Environment: XP, JDK7 45
            Reporter: Tilman Hausherr
            Priority: Minor
         Attachments: Kommunikationsbedingungen-Einlagen_FIDOR-Bank.pdf, Kommunikationsbedingungen-Einlagen_FIDOR-Bank.pdf-1-bad.png, kommunikationsbedingungen-einlagen_fidor-bank.pdf-1-good.png

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.
