koala otpimizing
Hi Everyone,
I know there's a c64 tool out there that helps with optimizing koala pictures for packing, but no idea what it is called. Anyone knows?:) Timanthes would do the job for me aswell with its nibble swapper tool, but is there a way to load/save a native c64 koala format picture with it ? *.prg doesnt works, what format does it expect to be .prg anyway ?:) |

charmem $3f40-$4327

hires or multicolor?
I've got a pretty nice tool to optimize Hires bitmaps (commandline tho).
BTW, Timanthes can also optimize by itself, there's an auto-option built in if you know where to look ;) |

Timanthes can't load .prg, it's one of the many flaws :)
I suggest you use WVL's little tool (or wait for ninja's, as he seems to have something aswell... it will probably use lots of illegal opcodes, though ;) |

but my little tool only works for hires, since I made it especially for Trans*Form.
I think it's a must for Timanthes to load .prg's, or at least be able to convert VICE-screenshots to restricted mode, without having to recolor all the colors. (just a new c64-colorramp option, to convert pixels to the nearest c64 color will be enough, me thinks)
I think I'm getting RSI just from doing all that recoloring.
Now that I think of it.. I also have a tool to optimize multicolor bitmaps :D It's part of the PDtool, to optimize the backgrounds of Pinball dreams :) |

@Mirage:
If you need something to load/save Koala pictures (and Amica Paint while you're at it) take a look at my gfxpack functions: gfxpack-20070308.tar.bz2
There's a function `read_file()` which will load a file and (re)allocate memory dynamically while loading. It also has the option to skip the load-address of a .prg file.
Not finished at all, many more file formats should be added. I'm actually writing this so hopefully Tao's cbmplugs can load/save Amica Paint and other packed files ;)
Ofcourse it's all written in ANSI-C, not C#, but I think it should be easy enough to write a wrapper for it.

to make the data more compressible but keeping the data structure intact, some type of routine can be used to swap col nybbles, 2bit mcol pixel pairs, etc until thedata compresses to a smaller size than usual

Try this one:
GFX Transformer 1.0
Just load & save a koala. Every image will be cleaned after loading. |
