[Lazarus] Write array of byte data to TImage

[noreply at z505.com]

Is there any way to write array of bytes to a TImage?

LoadFromStream doesn't appear to work, as it does not contain, AFAIK the 
bitmap header information that would be stored in a file...

i.e. is there any way to write raw array data to a bitmap or TImage.

Sorry, I haven't worked with images much... I assume the problem could 
be that load from stream must accept properly formed bitmap file, 
whereas I may be trying to just write the byte array itself that is not 
a properly formed bitmap/jpeg/png file with header information or image 
information.

RawImage.Data (PByte) is read only and cannot be written to AFAICT.
