Double pixel combination fixer

I need some tool to fix double pixel combinations. I was drawing a hires logo with project one under wine/linux. It didn't save my hires drawing (the file was there but actually 0 bytes). Therefore i saved it as koala (I know that it is the wrong format but what could i do else) and got it rescued to disk.
Unfortunately the bitmap got pixel combinations in double pixels exchanged. 00 -> 01, 11 -> 10, 01 -> 11, 11 -> 00
Is there a crossplatform tool to fix that?

PicConv if done correctly... Runs in Windows and under Wine.

Otherwise let me take a look at it :)

Thank you for hinting me on the pretty useful PicConv. I was not aware of this tool.

Managed it, but needed to remadd some pixels again. Hires information was already lost. Thank you, again.

Maybe I'm too oldschool, but couldn't this be fixed by some 6510-code
...
ldy bitmapbyte
lda correct_byte_tab,y
sta bitmapbyte
...
wrapped up in a loop?


But yeah, it's 2021 already and PicConv is without doubts a really nice toy :)

The issue is not with project one.
I stumbled over the same issue with Pixcen. I think sth does not work with WINE which results in a 0 byte bmp.
Why on earth this only happens with the bmp file format, i don't know.
However, my data is save, now.
