When will hardware transparent be avaible

Can we allocate hardware if we only have surface less than 128x128 and less on
1 mb of data on a 2 mb video card and hope all with go withouh errors ? Or will
SDL look after all this problems ? And why do you suddenly get thoses problems,
hardware worked on win 32 no ? I don’t udnerstand why transparent bring all
thoses problems.

Before, SDL supported hardware acceleration of hardware surfaces, and
system surfaces to hardware on those rare boards that support it.
I just verified that it worked. I didn’t test it thoroughly enough
to make it really useful.

The problem I’m having is that on almost every test platform I’ve used,
either hardware transparency is not supported, or it’s so slow accessing
the video memory that the hardware acceleration isn’t worth the effort.
I’m trying to figure out when it’s appropriate to use hardware accelerated
tranparency.

I think for now I will remove hardware transparency support.

See ya!

You mena, that if I my game uses a lot of transparency, I’ll have to use
software ?>

See ya!

I figured something out. I’ll test it when I get home.
