I tried to open an EPS image with Pyzo, I have installed PIL and Ghostscript (as I saw that it is necessary on some other websites'topics), my code is:

from PIL import Image
im = Image.open('''myimage.eps''')
im.show()

but when I run the code, Pyzo return me:`

OSError: Unable to locate Ghostscript on paths

I tried to look into it on several websites but it seems pretty complicated for a novice coding student.

I am working on Python 3

Thanks for help guys,

(oh, and I'm French, so maybe my English is not really perfect !)

In case someone else encounters this issue: It seems that Ghostscript has not been added to the paths properly. For those running Win7, here is a fix:

Go to: Control Panel -> System -> Advanced system settings -> Environment Variables...

Find the variable "PATH" -> Edit... -> add the path to your ghostscript binary folder, e.g.

C:\Program Files\gs\gs9.22\bin\;

to the end of the variable. It should be separated from the previous entry by a semicolon.

I had to restart for the changes to take effect.
