The code for writing data files is now completely finished. A GNU-style configure script and new Makefile have also been added, as well as some other general changes. The code is now available via anonymous CVS; see the project summary for details.
Some of the data file handling code has been written. This includes the low level stuff for reading and writing to files. The next logical step is to formalize a data structure for pcm to internally store the data. Basic documentation for this has been added to the Docs section.
After the internal data storage stuff is taken care of, and possibly after some more graphics code (namely thumbnail handling), it'll actually be time to start working on the GTK+ GUI. Yay! ;-)
Two technical documents have been added to the Docs archive. The first is the planned specification of the pcm data file format. The second is pseudocode for the resampling algorithm to be used for resizing images in pcm.
Welcome to the pcm project page. pcm is still in the planning phase. Please feel free to use the Forums to get involved, and help decide what directions the project should take!
