Hi,
Could you tell me why vncserver doesn't support 24bit-per-pixel depth?
Are you going to implement this depth in newer versions of vnc?
I'm not sure but there are many reasons to not implement 24 bits colordepth.
- It is covered by using 32 bits colordept, just not using the upper 8 bits.
- It takes additional time to implement.
- It results in additional code, including additional bugs.
- 24 bits is not a native integer width, 32 bits is.
- 24 bits needs special care in most handling.
- 24 bits numbers are sometimes optimized to 32 bits anyway
- 24 bit colordepth is sometimes using 32 bits numbers anyway
On the other hand, 32 bits colordepth isn't always 32 bits colordept as
you'd expect: It is 3 bytes for the 3 major colors (red, green and blue)
and an additional byte for something else. This can be brightness (with
video stuff), depth (with 2,5 D), layer, fogginess, opacity or other
sutff. I donnot know what VNC does with it.
Hence, no I donnot think 24 bits colordepth will be implemented...
... However, I'm not a VNC specialist, I'm just using my software
development knowledge.
