pngtools is a suite of commands that I needed to make PNG easier to use in my own development. I have been coding TIFF images with libtiff for some time, and the tiffinfo, tiffdump, and tiffcp commands are quite useful for that code. I have therefore implemented similar commands for libpng.

Wow, this is a blast from the past. When I wrote the pngchunks command in 2003, I had never seen a 64 bit machine, and knew enough to check that an int was the right size, but not enough to just use the guaranteed-to-be-32-bit version from day 1. I'd pretty much forgotten about this code until I got pinged about this Debian bug. The bug reporter is entirely right, this was lame.
PNGtools 0.4 should be 64 bit safe. The pngchunks command works on my 64 bit machines at least.

Version 0.2 is now available. This implements the pngcp command, which can be used to edit the characteristics of PNG files. You can download the source from here.

In line with the maxim "release early, release often", here is the initial public viewing of my work on pngtools. At the moment, the only command that is implemented is pnginfo, which is pretty much there (apart from the command line options, which are rarely used).
I would welcome comments on the code, which can be sent to mikal@stillhq.com. The code is (c) Michael Still 2001, and is released under the GNU GPL version 2.
