Convert from HEX color to RGB struct in C

Question

How do you convert from color HEX code to RGB in pure C using C library only (without C++ or templates)? The RGB struct may be like this:

Answer 1

Assuming that your hex value is a 32-bit 'int' type, and that we use the RGB struct described above, then maybe do something like:

struct RGB colorConverter(int hexValue)
{
  struct RGB rgbColor;
  rgbColor.r = ((hexValue >> 16) & 0xFF) / 255.0;  // Extract the RR byte
  rgbColor.g = ((hexValue >> 8) & 0xFF) / 255.0;   // Extract the GG byte
  rgbColor.b = ((hexValue) & 0xFF) / 255.0;        // Extract the BB byte

  return rgbColor; 
}
