[jira] [Created] (PDFBOX-1990) Support creating PDF from lossless encoded images

Tilman Hausherr created PDFBOX-1990:
---------------------------------------

             Summary: Support creating PDF from lossless encoded images
                 Key: PDFBOX-1990
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1990
             Project: PDFBox
          Issue Type: Improvement
            Reporter: Tilman Hausherr
            Priority: Minor


Currently we support the insertion of TIFF and JPEG into a PDF, but not PNG. We can pass a BufferedImage, but this one will be JPEG compressed which is not a good thing for graphics with sharp edges. I suggest that we support PNG as well. It is possible because the Flate Filter supports both directions.

My implementation (coming in a few minutes) is just an RGB based start that begs for improvement.
