Display.py opens non-existing simplecv.png

[hadzibanov-kostadin]

I had an issue when setting up a display or running the show() method on an Image. The display class tries to open "simplecv.png" when initialising even if there is no "sampleimages" folder. I downloaded SimpleCV from SourceForge and the Ubuntu store, which hosted the version without sample images, however I noticed the faulty code is the same in the Github repository. Should I try and make a fix?

Here is the stack trace:

This issue has already been resolved. #213

I thought the developers wanted the sample images and tests to be opt-outs.
If I understood the code right, this is the Icon for the window, so if the sample images are optional, maybe it would make more sense to reside in a separate permanent folder, or at least the Display class to check if the file exists and possibly leave it empty if it doesn't.

So you blew away the samples folder? That was the root of the issue?

[hadzibanov-kostadin]

No, this issue happens when there is no sampleimages folder (which was the case with the Ubuntu store and SourceForge versions)

Sorry if I was unclear.

@hadzibanov-kostadin Ubuntu Store version? What version of Ubuntu are you on?

[hadzibanov-kostadin]

Ubuntu 12.04 LTS

[xamox]

Did you install from the .deb package?

[hadzibanov-kostadin]

Yes, the .deb package form SourceForge

Still the same from Ubuntu 14.04LTS !!
