problem with rgb and cmyk colorspaces.

[raouf123]

Hi,
I am converting PDF to Images. I use -colorspace rgb but it creates a black background for the jpg.
In case I use cmyk, it converts the image with proper background but the jpg is not displayed by I.E. Please help.

What is your exact command? What version of IM and platform are you using (presumably Windows?). Can you post a link to your image? I believe this is a common problem with IE, but will defer to others on this as I am not a Windows users. However, if you provide a link to your image, then others can test with it.

Provide a link to the PDF. And give information on the versions of Windows, ImageMagick and GhostSrcipt. Tell us the exact command line you are using. Then we might narrow the problem. I have done lots of conversions PDF --> JPG under Windows and rarely met problems. (However, I remember there being a probelm with GhostScript version 9 ...)

If you pdf has transparency, then you will get a black background when using jpg for your output as jpg does not support transparency. Other issues may be the ghostscript device you are using. I believe it should be set to pngalpha (for saving transparent png), but am not 100% certain. But this may not allow multipage pdf conversion. This is all guesswork until you provide more information as requested above.
