Hi!
Assuming that I hope to understand the difference in bit deph
existing between a RGB image (24bit of color depth or 16.5M
colors) and a RGBa image (24bit of color depth plus 8bit
alpha channel).
I'd like to know whether 24/32bit , in a graphic card/PC
monitor loop , works the same way or not?
Pratically , my question is:
In a Pc monitor , does 24bit color depth generate the same
amount of colors as for 32bit color depth or not?
And if yes what is the difference?
Bye Luca
Welcome to HWC. :)
The accepted terminology seems to be "colour mode". For example, you have a "32-bit colour mode" or "32-bit display mode"... this can consist of 10-bits per colour component (10R + 10G + 10B) and a 2-bit alpha channel. In fact, this is what Matrox do with the Parhelia. The same 32-bit mode could also consist of 8-bits per component and 8-bit alpha. Alpha channel information is never sent to a monitor - it is always combined with the colour components.
There's a pretty good write up on it here if you're interested.
