display ghostscript version number through PHP in ubuntu

由 寵の児 提交于 2019-12-23 23:42:44

" --version"); print "$ver"; print "A"; ?> </body> </html> I can get the A printed, but not the version number why?

问题 Given a PDF, how can one get the layout mode of a PDF (or relative width/height) using a PHP lib or linux command line tool?

Thought of converting pdfs to ps, or using gs in some other way - like converting it to an image first, and getting the width and height of that. Is this the best way? 回答1: The solution I'm using is to use ghostscript to print

Ghostscript suppress output windows when called by command line

由 …衆ロ難τιáo~ 提交于 2019-12-23 08:04:35
问题 This is my scenario: I'm converting PDF files to PNG images calling Ghostscript by C#. This is the argument string I use: -dNOPAUSE -dBATCH -dFirstPage=1 -q -r300 -sDEVICE=png256 -sOutputFile=... But, in this way, when I call Ghostscript it shows a window where (before I've added -q ) there were output messages. I've tried adding -dNODISPLAY after -r300 . But in this way Ghostscript doesn't work and doesn't create images. Question: In which way can I suppress the output window? 回答1: If you
