encoded images
[ https://issues.apache.org/jira/browse/PDFBOX-1990?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tilman Hausherr updated PDFBOX-1990:
------------------------------------
Affects Version/s: 2.0.0
> Support creating PDF from lossless encoded images
> -------------------------------------------------
>
> Key: PDFBOX-1990
> URL: https://issues.apache.org/jira/browse/PDFBOX-1990
> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 2.0.0
> 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.
