[jira] [Commented] (PDFBOX-3844) Is there jpeg-compression of
images?
[ https://issues.apache.org/jira/browse/PDFBOX-3844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16069744#comment-16069744 ]
Tilman Hausherr commented on PDFBOX-3844:
-----------------------------------------
Have a look at {{JPEGFactory}}, it allows both BufferedImages and streams. CMYK is not supported in 2.0.6, will be supported in 2.0.7 if you pass jpeg stream.

> If you add large images in PDF, the resulting document becomes large. I've added about 80 images in size 2100x2100px in the document, and got about 400-500mb in the PDF file.
> From the document analysis (attached screen shot from Acrobate Pro DC), you can see that zip / flate compression is used for added images. I would like to be able to compress images in a document using jpeg compression (something like industry-standard compression filters). Is there such an opportunity now? Can it be add in the future?
> P.S. RGB and CMYK images are used.
> Thanks.
