Member Function Documentation

void PLSDLBmp::Attach SDL_Surface *  pSurface  ) 

Attach to an existing SDL surface. After the attach, the bitmap object besomes the owner of the surface. Any previous contents are destroyed.

SDL_Surface* PLSDLBmp::GetSurface  ) 

Returns a pointer to the internal SDL surface. Using this pointer, you can bring SDL and paintlib data out of sync easily. Handle with care.

virtual void PLSDLBmp::internalCreate PLLONG  Width,
PLLONG  Height,
PLWORD  BitsPerPixel,
bool  bAlphaChannel,
bool  bIsGreyscale
[protected, virtual]

Create a new bitmap with uninitialized bits. (Assume no memory is allocated yet.)

Implements PLBmp.
