I try to convert a PDF file into images, and this command works with other PDF files.
Doesn't create any images:
Code: Select all
convert -strip -profile USWebCoatedSWOP.icc -density 117.32 mamoetMagazine.pdf -resize 970 -profile sRGB.icm mamoetMagazine\big\img.jpg
Code: Select all
convert -strip -profile USWebCoatedSWOP.icc -density 72 mamoetMagazine.pdf -resize 406x570! -profile sRGB.icm mamoetMagazine\pages\img.jpg
What can be wrong? As I said the first command works with all other PDF-files I have tried.

PDF (12,7mb)

Your PDF appears corrupt or Ghostscript 7.07 or 8.15 are not sufficient. Both return errors when attempting to render the document.

With IM 6.3.1 and GS 8.53 I got both commands to render the pages if -density is moved after the input filename:
Code: Select all
convert -strip -profile USWebCoatedSWOP.icc mamoetMagazine.pdf -density 117.32 -resize 970 -profile sRGB.icm mamoetMagazine\big\img.jpg

We converted your PDF image to JPEG without any problems with Ghostscript 8.54.

I suggest you.... read the image before stripping and profiling!
Otherwise it is undefined if the strip is done first or the profile is done first.
See IM Examples... Legacy Command Line Style

Thanks for the replys. I tried to change my command and ended up with this:
Code: Select all
convert Wiseguide.pdf -strip -profile USWebCoatedSWOP.icc -density 117.32 -resize 970 -profile sRGB.icm img.jpg
The convert works but the images I get now is not as sharp as the images with the last command, what am I doing wrong?
Old image
New image
Regards!

-density is a input setting.. It needs to be defined before the image read.
The other options are operators and need to be applied AFTER the image has been read, in the order you want to apply them.
