(*.bmp)

Let's say we have an image file in an arbitrary format. The way to load it
is to write a function

/*
fname - bmp file to open.
width - return pointer for image width.
height - return pointer for image height.
returns - malloced pointer to 24 bit rgb data, NULL on fail.
*/
unsigned char *loadimagebmp(char *fname, int *width, int *height)

The problem comes when the image format, like JPEG, is so complex that you
can't reasonably be expected to decipher it yourself. Here you have to use
non-standard library functions, which may ship with the compiler or you may
cut and paste from the web.

Often you want to embed images in an executable. This is only practical
using some sort of automated tool. Such tools are included in MSVC++, but
are not topical here.

If I am understanding your requirements correctly, 010 Editor (an
inexpensive Windows application) can do this interactively or
programmatically.

See http://www.sweetscape.com/010editor/

For example, the tool exported a .bmp file exported to a C source
file:

//------------------------------------------------------------
//----------- Created with 010 Editor -----------
//------ www.sweetscape.com/010editor/ ------
//
// File : C:\WINNT\Blue Lace 16.bmp
// Address : 0 (0x0)
// Size : 1272 (0x4F8)
//------------------------------------------------------------
unsigned char hexData[1272] = {

In fact, the example screenshots are of an opened BMP file.

For example, the tool exported a .bmp file exported to a C source

Sure, I googled for "bmp information" and found this:

incredible.

If that is what he wants he can do it with debug, which AFAIK
still comes with every Windoze installation, and a little
massaging in any text editor. drdebug, which is available with
drdos, is a little better.
