    How to output an JPEG/GIF image in MSDOS

    I want to output a JPEG or GIF image in MSDOS mode by C/C++. I'm using Win-98 and turbo-C V3 compiler. I would like to know how to output a JPEG or GIF image in MSDOS Command prompt mode. If some URLs regarding the topic is available, will be better for further reference. Remember, I just want to output the JPEG or GIF image in MSDOS mode only, no Windows resource or API.

    Assuming you've mastered enough of graphics.h to plot pixels in a colour of your choice, the next step is to get to grips with the file formats

    GIF is pretty easy and only has 256 colours max (just like DOS). JPG is much more involved, and you're going to have to figure out how to reduce the 24 bit colour space in JPG down to 8 bits.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Shifting the colors right by 3 will fix the color space problem. Go to www.wotsit.org for the JPEG and about a trillion other file formats.

    Graphics.h sucks. You need a 256 color BGI driver and even it is slower than death.

    Go here for better/easier graphics.
