draw to memory
hi,
i'm developing a software in dd.as we know,draw speed is very slow,every operation about view requires regenerating and the screen splashed seriously.in former viewkit library,we used a memory dc to buffer the rendering and only simply changed the real draw dc to memory dc,then draw the memory dc.but now,dd's rendering use only device,i cannot find a draw dc.who can show me a way to reuse the memory dc?at least,screen dislaying is sudeenly disappeared although wait some time same.
thanks a lot!
i'll try to get a look into that.
