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?

public class CMYKTiffToJpegConvertor {

I gave up using ColdFusion-related image functions. I've still identified CMYK images that can't consistently be read by ColdFusion 10.  I also still have some apps running on ColdFusion 9 and needed a solution that was backwards compatible.

I started using CFX_OpenImage, but it hasn't been updated in a while.  I recently wrote a ColdFusion Custom Tag to access GraphicsMagick.  It can be installed on pretty much any 32-bit or 64-bit operating system.  It supports 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF.  This method is faster than CFImage and often generates much smaller files.

Here's the link to the custom tag if you are interested.:

Converting any JPG to a non-CMYK JPG can be done by:
<CF_GraphicsMagick action="Optimize" Infile="#ImageIn#">
