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 ?:)

I normally use Pico v1.3. How good is that compared to the other options mentioned in this thread?

I tried out Pico, it looks like a great tool, but what I understood is that you have to make some decisions to make it sorting? I only tried out the kill color function (CBM+K) which didn't give a good result yet.

Compress all 3 together as I could easily get 18580 bytes without any tricks:

Awesome! I saw that you had optimized Koalas in your solution - which program did you use for Koala cleaning/optimization?

That must be a side effect as I was lazy to rip the pictures and converted from screenshots instead.

A very positive side effect :-) - the resulting version is well suited for packing. What software or cartridge did you use to rip it?

Here's an easy one png2prg 0.1. converts 320x200 and vice screenshots to koala. It should optimize a bit automatically, but your miles may vary..

ps: only works if the screenshot contains a multicolor bitmap

Your png2prg is a great tool! I tested it with PNG version of the three reference images and it got everything right, including that the background in the "Short Circuit N0.5 alive" pic is white.

It seemd, however, that the tool used by Soci was a different one, since the result is less compressable than Soci's version, so I would be still interested in what he used.

Anyway, I bookmarked your png2prg for future use. Also, the golang code looks very tidy - gotta learn this language one day!

so am I, it could be interesting to see what method it uses, so I can build it into png2prg as well.

so Soci, spill the beans :)

Time to un-necro this thread again. I just released png2prg 0.8 which should be quite a bit better on optimizing images, especially compared to png2prg 0.1.

The recently released SPOT - Sparta's Picture Optimizing Tool V1.1 will probably give you the best size-optimized result, while my tool focuses on normalization, ease-of-use for demo-coders and supporting all standard graphics modes.
