Question

Is it possible to convert depth (measured z-distance in BYTE) to color (8 bit Grayscale) in Qt? My input is only a BYTE. I need to convert it to color. Please help

Answer 1

I assume BYTE is a typedef as follows :

typedef unsigned char BYTE;

As a BYTE can represent values from 0 to 255, you can use it directly to create a `QColor object, using the value stored in the byte as the intensity for the red, green and blue values :

BYTE depth = 128;

QColor color(depth, depth, depth); // greyscaled color
