Re: [pygame] Pygame, images, and Macs

[Thomas Kluyver]

I know very little about Macs, but one thing I hear from experienced
Python+Mac users is that you shouldn't really use the built-in Python for
any of your own code. That should be left for system tools which use it,
and you should install another copy of Python (either from Python.org, or
Anaconda, or Homebrew/Macports) to run your code with.

 The big snag seems to be image files. It doesn't seem to matter whether
 they are jpgs, pngs, etc. They sometimes display and sometimes don't.

 Our suspicion is that it is something in how either El Cap or Sierra
 processes image files that conflicts with pygame

 Has anyone found a solution?

Re: [pygame] Pygame, images, and Macs

[Bob Irving]

Sorry for the confusion. Here's what happens sometimes:

About 3/4 of the image shows, then shows a colored or vertical line. Rest
of image doesn't display.

We did a lot of searching about this, and it appears that Apple changed its
Python image handling system in between 10.10 and 10.11.

It makes sense.  But what we're wondering is if someone else has
encountered this and knows a simple fix. The one thing that is recommended
is to downgrade Python install, but we don't want to do that.

TIA,
Bob Irving

Yeah that's rather vague ... I'm on OSX 10.9.1 (forgot the name) and never
had a problem ... what about running from cmd line to see any output?

[pygame] Pygame, images, and Macs

[Bob Irving]

We're using pygame in our CS classes here and have found that the built-in
python (with Macs, which is what we use) works MOSTLY.

The big snag seems to be image files. It doesn't seem to matter whether
they are jpgs, pngs, etc. They sometimes display and sometimes don't.

Our suspicion is that it is something in how either El Cap or Sierra
processes image files that conflicts with pygame

Has anyone found a solution?
