Hello friends,
I'm on the road to port the BarsnPipes for OS4.1 FE MIDI-sequencer to MOS 3.17.
This will be also an upgrade to the "old" MOS-version 1.05.
Some issues were already solved (tasks, processes, interrupts, hooks).
Now I've the idea to create new ARGB32-Pointers for the program,
because the recoloring with LoadRGB32() does not work like expected.
The problem is, for this I need to convert the png images to ARGB32
colortables.
In the example for ARGB-Pointers, which is included in the SDK 3.16
I found a comment: "... converted from a png file with png2c

I found the source for this tool in the OS4-version.
Than I tryed it to compile it for MOS 3.17 - failed - no libpng.a.

Seached the libpng.a - found the sources - compiled it.
Tryed again to compile png2c - succes - BUT the program doesn't work.

So I would go the easier way: Is there any programmer which is
already using the png2c, and would give me a copy for my work to create
new ARGB-Pointers for BarsnPipes ?

Kindly thanks

Weird, I have always thought it to be part of the MorphOS SDK in someway as it also used for Ambient, but can't find it anywhere "public".

I do remember that I had 2 versions and only one would work to compile Ambient.


I just emailed you the one that lives in my c:

Hi, MorphOS currently has shared version of png/jpeg/z libraries. To add support of png just add -lpng_shared during linking stage. It will open png.library automatically.

Dear Alfred,
You can find png2c-1.1-ixemul.tgz at SourceForge.
