Thank you all for the interest,

anyway, after few tries I've seen that:

UNDER WINDOWS:

BitBlt procedure with the various cm_ modes -> fast, OK
Canvas.CopyMode together with Canvas.CopyRect -> blooody sloooow

UNDER LINUX:

BitBlt procedure with the various cm_ modes -> doesn't exist
Canvas.CopyMode together with Canvas.CopyRect -> fast, OK

So that I must use conditional defines to maintain sw portability...

Note:
The easy thing is that the cm_ commands used in BitBlt are the same of those 
to be used with Canvas.CopyMode; at least...


Cheers
