Re-Download and try again, please. I think I posted the wrong build originally.

I tried this with the new version (just downloaded) and got the same result. See attached images (note: the splash image was a screen dump from the .nb converter program -- could not figure out how to save it as a .bmp).

Ok, turns out it was broken for both converters, and I had only fixed one before. New build has been posted.

For the curious, it's actually a bug based on the low order Red color bits. Windows manipulated the pixel value on my behalf in order to distribute accumulated error when moving from a low color depth to a higher color depth. My logic assumed the pixel value I put in would be the pixel value I got out (sounds reasonable, doesn't it?), so when it wasn't things went awry. You see the artifact as green because the low order red bits were writing on top of the high order green bits. By pure chance, green does not write on blue because of an election I took in the code. Blue doesn't have a color after it to overwrite. So, the only color getting messed up is green, which explains why all the artifacts were green.

Fixed!

Thanks gguru.

For the record, I AM "the curious"...

Excellent work on this program by the way. =D>

No change. I don't know if this helps isolate the problem, I accidentally choose Qwest.nb and it looked ok in the BuildOS\temp folder. Rebuilt with HTC.NB and it again had the green artifacts in the BuildOS\temp folder.

I'm guessing this only affects certain colors, which is why the mostly grayscale or white screens come out okay and photos get totally messed up.
