If I defined a struct like this:
struct rgb
{
double r;
double g;
double b;
};
And each element is a percentage.
How to get these values from a .bmp file in C or C++?
Thanks!
The wikipedia entry for BMP files has a nice description of the file format. At the bottom of that page there is a link to this file bitmap.h which I’ve used before to read BMP files.
Basically, once you’ve read your BMP file, you should just divide each Red, Green and Blue value in the RGBA structs by 255 to get a percentage.
