Where to install additional plug-ins
Executables of the plug-ins must be copied to the plug-ins directory of GIMP.
On UNIX this is usually /opt/gnome/lib/gimp/<version>/plug-ins.
On Windows this is usually c:\programs\GIMP-<version>\lib\gimp\<version>\plug-ins.
All current installations of GIMP include the PostScript/PDF plug-in
which is required to read PostScript/PDF files with GIMP.
The plug-in uses GhostScript or a GhostScript-library to do this.
On Linux systems GhostScript is usually installed.
For Windows, at least the installer from V 2.8.4 on, installs
PostScript-support automatically. So GhostScript does not need to be installed
For older Versions of Gimp, here is how to install GhostScript:
Now you should be able to read PostScript and PDF files with GIMP.
- Go to
- Look for package GPL Ghostscript or AFPL Ghostscript
(non-commercial use only)
- Download a prepared Windows distribution like gs904w32.exe
- Start the executable and follow the instructions of the
- Copy the executable gswin32c.exe (not the gswin32.exe) from the
directory bin of the ghostscript installation to the Windows directory
(e.g. c:\windows or c:\winnt).
Or copy it to any other directory that is contained in the
environment variable PATH.
As an alternative, advanced users can set an environment variable GS_PROG
to point to gswin32c.exe (e.g. c:\gs\gsX.YY\bin\gswin32c.exe)
- Restart GIMP to activate the changes.
Please note that you must not move the directories of ghostscript once
the installation has finished.
Registry entries have been created that allow ghostscript to find
