CyBeRHQ.nl » iPhone PNG fixer-upper

General05 Jul 2007 04:47:51 by Marco

So if you happen to want to look at the images inside the iPhone, that is the bunch of PNGs no image viewer will shake a stick at, now you can. Just download my bit of code from svn://svn.poop.nl/pub/iphone-fixpng. Tested on OSX/Intel. There are instances where it will break, though you shouldn’t run into those with images from the iPhone.

You’ll have to compile it yourself. Install libpng into /usr/local and type ‘make’ in a shell.

Convert the PNGs into readable files by running fixpng input.png output.png. Then if you feel so inclined to make them pretty, you can flip the R and B channels around by running something along the lines of flipchannels input.png output.png.

Update: Also tested using a PowerPC Mac, so the Makefile in svn compiles to Universal Binaries now.

svn.poop.nl seems to be down. Is there a tarball somewhere else?

It’s up, but I’ve stuck a tarball here anyway: http://www.cyberhq.nl/files/iphone-fixpng.tgz

Can you publish the binary file?

However, I can not guarantee that they will work as they require a library that does not come with MacOS X. Also they’re PowerPC-only as I currently can’t generate Tiger binaries for intel. You might need to install this package, specifically the libpng one. Libjpeg is not needed.

Now…. wonder if I / you can modify this to reverse the process
On July 14th, 2007 at 18:49:55 Marco said:

Probably. The question is: is it necessary to do that?

That is, the fixpng part of it. The flipchannels part is reversible already and that would indeed be necessary.

When I try to run ./fixpng I get this error:
dyld: lazy symbol binding failed: Symbol not found: __NSSetProgramVars
Referenced from: /Users/danmarshall/Desktop/iPhone/iphone-fixpng/./fixpng
Expected in: /usr/lib/libSystem.B.dylib

dyld: Symbol not found: __NSSetProgramVars

Trace/BPT trap

I already ran make, and I got no errors. I have zlib (obviously, since it comes with OS X) and libpng installed. I am running 10.4.10

Any ideas? Please email me brutalentropy at gmail dot com. Thanks!

No idea, sorry :/ Did you try the binary version? (Don’t forget the libpng).

Can you post the source code? I am looking to make one for windows…thanks!

Um, I did post the source code.

Hi guys, I’ve coded a python script to normalize PNG files downloaded from the iPhone and iPod touch. As it’s python, it’s multiplatform, and it works for Windows users too.

Here is the code:

Enjoy!

thx for source, it’s really useful. one strange thing: if u take stock wi-fi signal bars from the iphone, only fixpng and flipchannel them then upload back, the bars will differ (u can see the difference on FSO image on lightgray background good)…
On July 27th, 2008 at 13:33:55 Marco said:

That’s probably because it might be expecting alpha premultiplied images. My tools just convert from weird pngs to readable normal pngs, but don’t do anything with the alpha channel.

Thanks a lot!!

Any ideas why this doesn’t work on the large texture atlas PNGs in many IPAs now a days? Example… PocketGod.

Likely it exceeds the buffer size. Send me one of the png? (e-mail via ‘contact’ link on front page)
