[jira] [Commented] (PDFBOX-4081) Image with JPXDecode filter not
render perfectly
[ https://issues.apache.org/jira/browse/PDFBOX-4081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16339503#comment-16339503 ]
Tilman Hausherr commented on PDFBOX-4081:
-----------------------------------------
This is a problem with the JP2 decoder, see PDFBOX-1819. Try this
- with PDFDebugger save the image into PDFBOX-4081.jp2 (attached)
- view it with your favourite viewer, see that it looks ok
- read this image file with ImageIO
- save it as png
- cry when seeing the result.
I'll reporting this on github later, but there's nothing we can do, except write our own decoder.
