The bits in …
WebTo create the header you can use the BITMAPFILEHEADER, BITMAPINFOHEADER and RGBQUAD structures from GDI defined in the header WinGDI.h Here is an example on how to fill the header data:
WebAIMTools operations also fully initialize the BITMAPINFOHEADER fields. Windows allows some fields to be 0 if the correct value can then be computed using other fields. … http://studyofnet.com/972234633.html
WebThe first of these headers, called BITMAPFILEHEADER, is 14 bytes long. (Recall that 1 byte equals 8 bits.) The second of these headers, called BITMAPINFOHEADER, is 40 bytes long. Immediately following these headers is the actual bitmap: an array of bytes, triples of which represent a pixel’s color.
