Tilman Hausherr commented on PDFBOX-2700:
-----------------------------------------

Funny thing is that the file you send me rendered correctly with the pre-change 
version. Maybe a bug in JDK6?

Btw. the DCTFilter work around with the color space codes solved most of the 
image problems I've reported earlier on developer mailing list (2014-08-26).

I didn't keep that one; maybe open an issue on the case that haven't been 
solved. I'm currently evaluating the twelvemonkeys jpeg plugin (PDFBOX-2694) as 
a possible alternative to the sun jpeg plugin.

> support JPEG color space code 11 (JCS_YCCK)

> In DCTFilter we have a work around for 4-component images which handles 
> certain color space codes to decide for YCCK and CMYK color space. I have a 
> document (C&EN journal issue, http://cen.acs.org/index.html) with some images 
> returning color space code 11 which should be JCS_YCCK. Adding this code for 
> YCCK type the images display fine.
