You could add a public byte/word property of TBitmap, say DepthConversion, and let the component/application decide whichever it needs :
0 .. for default color depth (of the file),
1-32 for specific color depth (your second case)
$FF for screen color depth
This may also be an enumerated type, whatever.

While reading the BMP file, i can translate them to the following color
depth :
1) use the color depth of the BMP file
2) a standard (say 32 bits) whatever the color depth of the BMP and of the
screen
3) use the color depth of the screen
NB : Delphi use the resolution of the screen. I think they did so because
under windows, if you use the color depth of the screen it work quicker
than any other color depth (M$ says so in the API description).
using the color depth of the screen seem to me a bad choice because if you
want to edit a BMP without displying it, you should be able to work with at
least the BMP resolution.
Which solution do think i should use?
