ghostscript

Does anyone know about stamping PDF file to PDF file and also controls for positioning PDF file stamp? I have a file orginal.pdf and logo.pdf . I want to stamp logo.pdf file to file orginal.pdf at the top left of file original.pdf . How can it be done with Ghostscript or pdftk ? It can be done with Ghostscript plus pdftk, but it requires at least 2 different steps. AFAIK, you cannot directly control pdftk 's stamp placement. By default it puts the stamp on the center of the page, and at the same time does a 'scale-to-fit' operation. So, you have to fix your stamp first so it is placed on an

Just installed Ghostscript 8.54 for Windows. Does anyone know of the minimum parameters to pass to gswin32c.exe to make it convert, say, someFile.eps to someFile.eps.pdf ? Since the question was about the "minimum parameters to pass to gswin32c.exe to make it convert, say, someFile.eps to someFile.eps.pdf" , let me give an answer: c:/path/to/gswin32c.exe ^ -sDEVICE=pdfwrite ^ -o c:/path/to/output.pdf ^ c:/path/to/input.eps or even shorter: gswin32c ^ -sDEVICE=pdfwrite ^ -o output.pdf ^ input.eps This will use the builtin, default parameters for Ghostscript. The most important of which, from

I'm looking for a Linux command line tool to compare two PDF files and save the diffs to a PDF outfile. The tool should create diff-pdf's in a batch-process. The PDF files are construction plans, so pure text-compare doesn't work. Something like: <tool> file1.pdf file2.pdf -o diff-out.pdf Most of the tools I found convert the PDFs to images and compare them, but only with a GUI. Any other solution is also welcome. I've written my own script that does something similar to what you're asking for. The script uses 4 tools to achieve its goal: ImageMagick's compare command the pdftk utility (if you

I read this post about how to convert PDF to CMYK, but when I try the accepted solution gs \ -o test-cmyk.pdf \ -sDEVICE=pdfwrite \ -sProcessColorModel=DeviceCMYK \ -sColorConversionStrategy=CMYK \ -sColorConversionStrategyForImages=CMYK \ test.pdf I does not get a pdf with CMYK color space, if my original pdf does not contain an image. If I add an image to it, I get the right result (checked with identify ). For example, if I create a svg with inskcape with one rectangle, export it to pdf, and then use the ghostscript command, it still gets a pdf in sRBG color space. But, if I add an image in
