Hi! Since I'm migrating my rendering code to OpenGL ES for iPhone, I need to change the calls to the methods that belong to the E2DSurface "buffer" (the one from ecd.dsp->buffer) so that they make use of ClassEDisplay directly.
The only function calls I haven't been able to port are the ones that make use of the "flags" and "property" parameters from E2DSurface::BltFast (for example, in those cases where I need to blit an image with a certain opacity by using the EFX_OPACITY flag). How can I write equivalent code for a semi-transparent blit when using OpenGL?
Thanks for your reply,
