Constructor.

WoopsiUI::Graphics::Graphics | ( | const Graphics & | graphics | ) | [inline, protected] |
Copy constructor is protected to prevent usage.
bool WoopsiUI::Graphics::clipBitmapCoordinates | ( | s16 * | x, |

) |
Copy a rectangular region from the source co-ordinates to the destination co-ordinates. Uses the DMA for speed.

Does not clip.
