Re: Higher priority.
Def: The later an image is drawn, the higher the priorty.
For example, the first call to BltBitMap draws the Carrier onto
the transparent background. (image looks as defined in dpaint).
Next, a Jet is drawn on top of the Carrier. So the Jet appears to be
on the deck of the Carrier (has the higher priority, because we
*see* it *on_top_of* all other images. Simply, the the last image drawn
has the highest priority.) Now, wherever the Jet image is defined
as other then transparent, its colors are changed when drawn on
top of the Carrier. Actually, as I think about it, no priority is
taking place other than conceptually. From the facts you have
stated in the past, it would appear that altering when an image is
drawn will just change the way the pixel color defintions are
modified. So, from what you have said, the only way to get *real*
priority is to blit into seperate planes.(?)
it's getting late, ah, 5:08 am. need to put in some dream time...
thanks once again for all the support.
