This is very helpful indeed, thank you. Awe-inspiring.
It occurred to me that I could edit the PIL/ImageShow.py, replacing
‘xv’ (in five places) with the utility of my choice and using
‘executable’ as the command.
Or, is this just not done?
It becomes a maintenance problem.
Alternatively you could:
Just write your own show function which accepts an Image and displays it
with your program of choice. You might need to write some equivalent
code which saves the Image to a file first, and removes it afterwards.
You could copy the show() code into a function of your own (i.e. in your
own codebase) modify that to suit, then monkeypatch the class:
Image.show = your_personal_show_function
when your programme starts. That way the code changes are not in the PIL
code.
I think this is a bug/misfeature in the PIL code. On all 3 major
platforms there is a way to invoke the standard program for a given file
or URL. On Windows, it is "cmd.exe /c start ...", on OSX it is "open
...." and on Linux it is "xdg-open ...". That way the file is opened by
whatever the user has set in his desktop environment.
Technically, xdg-open needs not to be present on Linux, though it is
usually installed.
