Tilman Hausherr commented on PDFBOX-3214:
-----------------------------------------
This is still a "how to" question and not a bug. It works as intended. The
images you have attached are indeed not CCITT T4 or T6 compressed (also known
as "fax 3" and "fax 4", they are LZW compressed and with more than 2 colors, so
you can't use the CCITTFactory class. Instead use the LosslessFactory class,
which you already do for PNG:
{code}
BufferedImage bim = ImageIO.read(new File(str));
pdImage = LosslessFactory.createFromImage(document, bim);
{code}
The reason is that the CCITTFactory class uses the existing compression to put
the images inside the PDF with that compression.
There's currently no way to convert to CCITT compression from a BufferedImage.
This might come in the future (there is already an issue), but that one would
only be for bitonal images.
Please use the user mailing list
https://mail-archives.apache.org/mod_mbox/pdfbox-users/
for such questions. Better, use it always, as long as you're a newbie.
