Mikhail Semionenko updated PDFBOX-3844:
---------------------------------------
Description:
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.
