Nice work! I made a similar program for the TI-89 named Kraphyko, but the 24K limit prevented me from going farther.

Faster image saving and loading.
I got it to load a new image. :P

More screenshots(doodles):

Looks quite nice! :)

I'm experimenting with trying to get it to save BMP. The problem is that I try to open it and it says that it is corrupt.

Here is my saving code:

--- Code: ---void saveBMP(char *filename, color_t *data, int width, int height){
    BMPHEAD bh;
    memset ((char *)&bh,0,sizeof(BMPHEAD)); /* sets everything to 0 */
    memcpy (bh.id,"BM",2);
    bh.reserved[0]  = 0;
    bh.reserved[1]  = 0;
    bh.headersize  = 54L;
    bh.infoSize  =  0x28L;
    bh.width     = width;
    bh.depth     = height;
    bh.biPlanes  =  1;
    bh.bits      = 24;
    bh.biCompression = 0L;
    int bytesPerLine;

    bytesPerLine = bh.width * 3;  /* (for 24 bit images) */
    /* round up to a dword boundary */
    if (bytesPerLine & 0x0003)
    {
        bytesPerLine |= 0x0003;
        ++bytesPerLine;
    }
    bh.filesize=bh.headersize+(long)bytesPerLine*bh.depth;
    int size = bh.headersize+(long)bytesPerLine*bh.depth;
    char * PATH;
    PATH = alloca(strlen("\\\\fls0\\")+strlen1(filename)+strlen(".bmp")+1);
    strcpy(PATH, "\\\\fls0\\");
    strcat(PATH, filename);
    strcat(PATH, ".bmp");
    unsigned short * pFile = alloca(2*(strlen(PATH)+1));
    Bfile_StrToName_ncpy(pFile, (unsigned char*)PATH, strlen(PATH)+1);
    Bfile_CreateEntry_OS(pFile, CREATEMODE_FILE, &size);
    int hFile = Bfile_OpenFile_OS(pFile, 2);
    Bfile_WriteFile_OS(hFile, &bh, sizeof(bh));
    char *linebuf;
    linebuf = (char *) malloc(bytesPerLine*sizeof(char));
    if (linebuf == NULL){
        Bfile_CloseFile_OS(hFile);
        return;
    }
    int line;
    for (line = height; line >= 0; line --){
        for(int i = 0; i < width; i++){
            linebuf[i] = data[line*width+i];
        }
        Bfile_WriteFile_OS(hFile, linebuf, sizeof(linebuf));
    }
    Bfile_CloseFile_OS(hFile);
    free(linebuf);
}

I don't think loading the data is going correctly. Can someone please help?

DJ Omnimaga:
This isn't the right sub-forum to ask for programming help. You should use the Lua or C programming help section for that, else only people who check Casio stuff will see your request.
