    Please help, is there any WIN32 program for convert JPG,BMP or any other pictures to pixel byte? One Byte is one pixel of 0 to 255, where the number is the color of pixel. I have this on my old Dos comp,but i need this on WIN32.

    Picture of resolution 6x3 of 3 color become a file

    Inside the file

    I have no progam with this functionality, but I think simple BMP conversion will be enough to you.
    Thats it because BMP in 256-colour mode have picture content encoded in this manner you like - 1 pixel is 1 byte. Pixel byte is index of colour in palette.
    BMP format is quite simply - look at ->link<- and search "BMP" (I can't paste link to BMP because wotsit is protected against spam automatas).

    You can load BMP file to Graph2Font and save it as data file. That's not what you exactly expected but better than nothing.

    Yeah, but in G2F is no resolution. If I need onyl 32x50 or bigger as 319 x 196 and soo....

    You can get smaller pictures in G2F but they size is always multiplicity of 8, i.e. 32 pixels, 160 pixels.

    PS. Have you tried save option in pc pictures viewers like XnView and IrfanView?

    There are so many formats in extended load/save menu that it was pointless for me :). However you should take a look.

    as mono mentioned BMP file should be the file type you`re looking for. You can view the content of the 8bit per pixel BMP file by using some simple tool(for example BIN2ASM by Vega).At the beggining goes the header then data pixel by pixel,line by line.

    Its not bad, but not correct program,there symbol , and so.. I need better program to do this DAT BYTE file.
    If a have BMP picture of 256 color, resolution of 320x200 then that must do a DAT file 64.000 where 1 byte has number from 0 to 255. Than a can it load do disk ATR image an load to GR8 :D ok? has anybody this program???

    maybe just convert your BMP to RAW file (using IrfanView).RAW (in 8bpp mode) is simply BMP minus header and array of colors,just pure data.

    Ou yeah, I think that it. Questeion to this, when I have BMP, can I do it only with 4 or 16 color? That the byte become number from 0 to 0F ?? Thx.
