[PD] bitmap sequencer and flext png library wrapper

Hi some,

I watched the thread about trackers and pd and since i still had not found a sequencer software to fit my needs (shaketracker won't compile, jazz is not quite what i want) i decided to use bitmaps for sequenceing.

My favorite mapping is like this: (using hsv conversion) x->freq y->bar h->waveshape-index s->intensity v->velocity A=aux-param

As i somehow missed gridflow until now, i wrote a little png library wrapper using flext. Now gridflow is just too nice but if anyone is still interested in these 400 lines of code, just email me a note and i will put it online somewhere.

It can read 8 or 16-bit CLUT-mapped, RGB, RGBA, Grayscale, Grayscale+A png files. Until now it can not write files or modify a loaded bitmap. It was implemented on a linux box so porting is untested but IMO should be trivial.

I just started using gridflow so i may decide to continue developing pngread later.

BTW: I would like to implement flext-threads, but how? Am i yet again missing the flext docs or aren't there any beyond the source? Why do the flext tutorial makefiles have references to thread examples but i cannot find them?

Happy patching
