Hi all

i am new to imagemagick and ghostscript

i am using imagemagick 6.5.4 and ghostscript 8.64 to convert the pdf to jpg and everything looks fine.

convert -density 150 -quality 85% -colorspace cmyk -type truecolor pdf jpg

the only probelm is there is image and text in the orginal pdf file. in the converted jpg file, the image is too large and cover the text.

does anyone can help me to fix this problem. Thanks a lot

is your pdf in cmyk or are you trying to create a cmyk jpg? are you trying to make the jpg with 150 dpi?

your syntax may be wrong? see http://www.imagemagick.org/Usage/basics/#why

most of the time you use

convert input.pdf options output.jpg

with cmyk pdfs, you may have change colorspace to rgb, so

convert -colorspace rgb input.pdf options output.jpg

which is done when reading in the input, so the -colorspace comes first.


You might post a link to your image so others can view it and test with it.
