[licensing] command-line conversion pdf>jpg in my software

Post by narzissm »

Hi,

I developed a scan-tool that uses imagemagick to convert scanned pdfs into jpeg format for viewing the pages before sending them to a dms. I know that as long as I include the license of IM in my software I'm allowed to use it under any license.
Besides that I read, that IM uses Ghostscript for conversion, which is licensed under GPL. If that is true, do I have to license my scan-tool under GPL because of the so called "viral-effect" of that license?

Best regards

ImageMagick can link to the Ghostscript library or it can call GS from the command line. You can avoid the GPL requirements by calling GS from the command line. Simply add --without-gslib to the configure script command line when you build ImageMagick. In general we can answer questions concerning the ImageMagick license. Contact the Ghostscript development group for questions pertaining to their license.
