Tilman Hausherr commented on PDFBOX-1990: ----------------------------------------- I added writing bitonal and grayscale images as single color samples and improved the unit test in rev 1579990. I replaced the test image with one with some color. I had to disable the 256 grayscale part due to a bug for which I fill file a separate issue. > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
