The version of Gimp for Windows is nothing more than a port of the most complete version for Linux. By itself Gimp on Windows has nothing to envy to the Linux version, it was not for some small additional packages that are enabled natively on Linux. One of these is Ghostscript.
Ghostscript is a collection of free programs based on an interpreter of page description languages PostScript and Portable Document Format, both of the Adobe.
Regarding the file EPS, always from the same source:
Encapsulated PostScript, the EPS, is a document PostScript DSC-comply with additional restrictions intended to make EPS files usable as a file format for images. In other words, EPS files are more or less self-contained PostScript documents and reasonably predictable that describe an image or drawing, that can be placed within another PostScript document.
In short, an EPS file is a vector graphics file, and as such also by increasing its size does not lose image quality.
The problem for Windows users occurs when attempting to open an EPS file with Gimp. To open it you need Ghostscript, Gimp but does not include, you need to install it separately from official website. Even after downloading and installing the file is not immediately recognized, but you need to add an environment variable in Windows, so that the EPS file can first be converted by Ghostscript to paths and then switched to Gimp.
The variable that we will create is called “GS_PROG”, and will have to call the executable Ghostscript “gswin32c.exe”.
After installing Ghostscript executable is placed in this location: “C:\Programmi gs gs8.53 bin gswin32c.exe“.
To add the environment variable we go on “Control Panel” – “System” – “Advanced” – “Environment Variables“. The name to assign to the variable is “GS_PROG“, the path is the one found earlier “C:\Programmi gs gs8.53 bin gswin32c.exe“.
Let's OK to all the windows open so far, restart Gimp if we left it open and we try to import an EPS file. This should open a terminal window, and import should be successful in a moment.
