libpng defeated!

Hah! Turned out there were two problems with libpng on the nds:1. png_zalloc(), which allocates memory for zlib, was refusing to allocate any memory, thinking it was too much. I just removed that check and it works. Boy this was annoying to track down.
2. I forgot a FAT_fclose() in there, so the file was 0 bytes (since it never got flushed to disk)

Latest update — now no more confusion over .bin or .rle, since it directly spits out png’s!

  1. Yay! for some reason no more gaps! Also it didn’t matter if they were fast or slow, light or hard, the gaps appeared in 90% of lines I drew in R6… but now in R7 they only appear on about 5% of the lines! GJ whatever you did :)

    To celebrate, I drew a lil more featured pic…

    Keep up the good work! (Please oh please add in a swatch for black and white… it’s so hard to select 0,0,0 and 31,31,31)

  5. Can’t get it to work on Supercard CF– the top screen with instructions loads, but the bottom screen remains black and undrawable. Looks cool though!

  6. To digicide:
    Can you tell me the last few lines of text on the top screen?
    There should be a line “fat…OK” and then below it, some lines like “Line Size: 1″ and “Color: …”

  7. Wowow! Nice! Those lines are quite smooth, nice job. How far are going to push this project?? It would be nice to have some more tools…. u_uU

  8. Yeah, my top screen’s text ends with

    L – color picker

    X – save to img.png (best)

    FAT. . .

    then the rest of both screens is black.

  9. Hmm…I had reports from other people as well who say it doesn’t work on Supercard CF. I’ll have to look into it…it seems to be a problem with the fat lib, since it is failing in FAT_InitFiles().

    For now, here are two more images:
