A stupid question?

SDL Development

Hi!,

I’ve tried to make a SDL_Surface of 20000x18000 and SDL don’t want to make
it,
(well, maybe I am mad to make so big screen but why not ?)

What are the max size you use ?

um, that’s like 343 megs just for 8 bit…

hmm let’s see
20,000 x 18,000 x 8bits =2880000000 bits or 360,000,000 bytes or about 344
MB

multiply that by 4 to get the memory needed for a RGBA surface
1.3GB of memory is needed to make that surface.> ----- Original Message -----

SDL imposes no limit on the size of surfaces (except that some members
are 16-bit so keep the pitch under 32768 bytes). Of course, you need
enough memory. And a psychiatrist

big surfaces are imho integrated into "Desperados - Wanted Dead or Alive"
and they seem to serve a great job… but although i think they are some
kind of tiled so only the needed screen resolution(+?? pixel[for scrolling])
is always in memory

I think the time of complex tile engines is over … and we will see more of
the very detailed and different “new” engines
