Command Line Tool crashes in

[psineur]

Original message by Davewise from cocos2d-iphone.org forum:

I think something is going on with the latest version of tileCutter and png files. I grabbed the latest cocos2d-iphone-extensions 0.2 and opened up the cocos2d-extensions-ios.xcodeproj. I looked in the CCBigImageTest folder and noticed that the png files pointed to in the xcodeproj are replaced with jpg files. So I saved them as png files and changed prepareTiles.sh so that it would point to the png files. tileCutter will crash if you do this. Note that it didn't crash in the past when I tried this. You can try this yourself to see the results. Here is the output from my terminal:

./prepareTiles.sh

@alexeylang, you have Snow Leo, can you try to reproduce this on it please?
You just need to got to the extensions repo and then execute this from it's root:

cd Tests/CCBigImageTest/preparingResoures/
./prepareTiles.sh 

There might be bash errors about no texturePacker installed, but it shouldn't crash like in message above.
Thanks!

More info to add. This happens only when my input file is png and my output format is png. If I change my input file to something else. The crash goes away.

I had the crash happen as well, using Lion, SDK 5.1 in XCode 4.3.2

According to the debugger, the crash happens here, in TileOperations.m:

143: NSData *bitmapData = [NSBitmapImageRep representationOfImageRepsInArray:representations
            usingType:fileType properties:nil];

It seems to only happen when output is PNG.
Also I noticed that if setting the output to JPG OR commenting out the actual creation of the images, the "plist" file that is produced contains NO sizes, just {{nan,nan},{nan,nan}}, this might be related to #4 no?

My images are DPI 72 tho...

I fiddled with it for a few hours but couldn't figure out the problem. Now that I know about the sizes (and #4), maybe I'll give it another go...

Edit: probably nothing to do with the previously mentioned #4, I did at one point get the following error:

libpng error: invalid zlib compression method or flags in idat
