iPhone: NSFileManager/NSDirectoryEnumerator Crash?

Hi All, I've got a method that refreshes a list of files in a directory. The code executes properly on the first invocation, but crashes on the second invocation. The cause of the crash is walker = [fileManager enumeratorAtPath:directory]. Any ideas on the cause? I experience the crash with both

Re: Reading RGBA pixel values from image on disk

Hi Quincey, if I re-open the same TIF file with Photoshop, I can quite see the half-a-transparent pixels. So, it seems that the alpha information has been properly saved within the TIF file. I would like to know how to manage a file like this and retrieve the transparency (alpha) of those pixels.

Reading RGBA pixel values from image on disk

Hi, I have to read all the RGBA values of every pixel of an image on the disk, as tif, png, jpgŠ I read the imageRep with imageRepWithContentsOfFile and get the RGBA values with "colorAtX: y:" It works quite well with png images with "non alpha premultiplied" bitmap format. In this case I get a bit
