ProjectOne - JPG convertion to certain colors
Hi,
I have made a JPG picture consisting of only 2 colors (dark grey and light grey).
Now, I want to convert this to a koala paint picture by using ProjectONE.
In the import to ProjectOne, I choose to have background as black. Which works fine.
However, I want the 2x colors to be only mapped to the ScreenRAM colors ($4000-43e8), and not use the colormap in $d800-dbe8. That way, I can in code use a fixed #$xx value to get the colors out on screen, instead of using more memory for both the screenmap AND colormap.
After all, it's about saving memory...
Is there a feature in ProjectOne that allows to set the convertion to only map to screenmap colors?
If not, someone start implement it! ;)

@Magnar: I'm not able to answer your question but i have a quick advice for you. don't use lossy compression formats like JPEG for this kind of a case. they ruin exact pixel colors. use PNG like formats instead. |

for this kind of specialised stuff my advice would be to knock up a small konverter in your favourite programming language.
that said, i think you can do what you want using timanthes. no idea how though =) |

Vicpack (vicpack V0.10) will first use the screen RAM only and only start using color RAM when there are more than 2 colors. So the output should be fine for what you need. |

Ya, in Timanthes use the remap function, you may set bitpairs per colour, so you can use simple lda #$bf sta screen,x code to poke your screenram. (But I'm sure Amica Paint and Boogie Down Paint can convert like that too using a Koala picture) |
