How does one convert 16-bit RGB565 to 24-bit RGB888?

Question

I’ve got my hands on a 16-bit rgb565 image (specifically, an Android framebuffer dump), and I would like to convert it to 24-bit rgb888 for viewing on a normal monitor.

Answer 1

There is an error jleedev !!!

unsigned char green = (buf & 0x07c0) >> 5;
unsigned char blue = buf & 0x003f;

the good code

unsigned char green = (buf & 0x07e0) >> 5;
unsigned char blue = buf & 0x001f;
