BMP grid generator

Recommended Posts

Hi I am working on a program that will auto-generate a bmp with a grid. The program takes as input a number (for example, if you enter 8, it will make 8x8 cells). Anyway, my question is how do you actually go about writing the bmp file after I''ve done all the calculations?

Create an object of the BITMAPFILEHEADER and BITMAPINFOHEADER structure, and fill the data members in. See msdn for the meaning of each member. Than write the BITMAPFILEHEADER to the file and after that the BITMAPINFOHEADER. Than, if your uses a palette, write the palette, and after that, write the image bits to the file. Now close the file, and you have a bitmap.
