Reading CMYK jpeg images
Hi,
I am unable to read CMYK jpeg images from coldfusion 10. Below are my server configuration.
Coldfusion 10 (update 14),32 bit and windows 2008 r2 64 bit,jre(1.6)
i found below code in java and implemented in coldfusion,but the code is working fine in coldfusion 10 64 bit,but not coldfusion 32 bit.
Shall i get any help on this?
