Reading a CMYK JPEG image

Post by FlashFan »

Hi guys

My program extracts images out of pdf files. There are many JPEG-images in pdf's that have cmyk colorspaces.
How can I read the image that the colors are correct?

convert -colorspace RGB -density XX image.pdf image.tiff

use the -density to set image quality/size for the output image

or you need to use profiles http://www.imagemagick.org/Usage/formats/#profiles
