what is the pixel format of EColor16MU?

[slinx]

how rgb component are packed in EColor16MU format.

(i) 1st byte -> unspecified, that means the value here need not to be take account while converting to other formats?

(ii) (2nd, 3rd, 4th byte) -> (RGB value) , in which order rgb values are stored?

(iii) any details about the format?

(iv) how this format differs from EColor16M format?

Thanks

It is RR, GG, BB, UU in the memory or 0xUUBBGGRR when read as little-endian.

(i) 1st byte -> unspecified, that means the value here need not to be take account while converting to other formats?

Actually it is the last byte. And yes, it is unused.

(ii) (2nd, 3rd, 4th byte) -> (RGB value) , in which order rgb values are stored?

See above. But you can also try it in 3 minutes in fact.

(iii) any details about the format?

Details?

(iv) how this format differs from EColor16M format?

EColor16M is packed, there is no unused byte between. Just 24-bit number formats are rare in C-like languages. While 32-bit integers are usually available.
