    Default Hex editor

    Is there a simple windows based hex editor for looking at .bmp files on disk that someone could reccomend?
    I need it to find where the image data begins in a file, either on hard disk or an SD card. Freeware would be good!
    Thanks
    Ron

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Thanks Steve,
    I'm just dubbing now and I hate to invest substantially in a piece of software for a project that may have no practical application.

    I bought the Hex workshop. It is inexpensive, and should be bug free.

    GOOD! Smart choice!

    I use it often to edit/create Text EEPROMs. Easy to figure out how your LCD scren (of any type) will looks like.

    The only issue is there seems to be a lot of data bytes that appear to do nothing before the image file. I need to find the file format to find out what it all does!

    Well, the first link i've posted was for an old BMP format i think, sure there's other info on much recent format such as 24, 32 bits one somewhere.

    Post Psc

    You should be able to find some info a long with source code on PSC that explains the file structure of a Bitmap. I don't think the format of them is terribly
    complex, nothing anywhere near as difficult as a jpeg or animated gif. Happy searching! http://www.planetsourcecode.com

    Post BMP format

    Here is a link for the BMP format..

    http://www.odec.ca/projects/2004/chi...mpresearch.htm

    Anyone have any ideas for code to extract the pixel data? I would suspect it to be something like open the .BMP for read, then open an ASCII file for write, and then stream the data through the PIC...
    I have an application coming up where I need to determine the randomness of dots in a balck and white BMP image. I'll post anything I come up with here... stay tuned
