[magick-users] Convert CMYK PDF to RGB

[Thomas Arildsen]

I need to convert a CMYK PDF file to RGB color space in stead.
I have tried the following:
   convert -colorspace RGB infile.pdf outfile.pdf

This gives me two problems: the original file is vector graphics, but 
the converted file is rasterized (low, ugly resolution) and apparently 
has a completely different page size; and, the converted file does not 
have fonts embedded.
Can I fix these problems? If someone knows of other solutions than 
ImageMagick, I am open to those as well. The color conversion quality is 
not important as long as black remains black - the PDF files are all 
black-and-white images.
Best regards,
