| FrameBuffer (const FrameBuffer &bitmap) | |
Bitmap subclass designed exclusively as a way to wrap the framebuffer in a bitmap object. It can then be treated as any other bitmap - it can be drawn to with setPixel(), blit() and blitFill() methods, and it can produce a Graphics object for more complex drawing functions.
The FrameBuffer class automatically switches from using the DS' framebuffer (more accurately, a 16-bit background) to using an SDL surface if Woopsi is compiled in SDL mode.

Destructor.
| WoopsiUI::FrameBuffer::FrameBuffer | ( | const FrameBuffer & | bitmap | ) | [inline, protected] |
Copy constructor is protected to prevent usage.
