    Direct edit if palette entry in PNG?

    i have made a B/W picture into a png file and optimized it with ~800 iterations of pngout).
    the png file is 1bit palette entry

    however now i can se that the palette entry is wrong. the black is only 11,11,11 (decimal) and not 00,00,00

    i now wish to just edit the palette value without losing the optimized compression.

    is there a tool for that or do i need to run my 800 iterations again ?

    the reason i wnat to change is because i want to run another 200 iterations with 1bit grayscale instead of 1bit palette to see if it improves compression
