void gcn::AllegroGraphics::_beginDraw | ( | ) | [virtual] |
Initializes drawing.
Called by the Gui when Gui::draw() is called. It is needed by some implementations of Graphics to perform preparations before drawing. An example of such an implementation would be OpenGLGraphics.
NOTE: You will never need to call this function yourself. Gui will do it for you.
Reimplemented from gcn::Graphics.

References mTarget, and pushClipArea().
void gcn::AllegroGraphics::_endDraw | ( | ) | [virtual] |
Deinitializes drawing.
Called by the Gui when a Gui::draw() is done. done. It should reset any state changes made by _beginDraw().
NOTE: You will never need to call this function yourself. Gui will do it for you.

int | height | |||
) | [virtual] |
Draws a part of an Image.
NOTE: Width and height arguments will not scale the Image but specifies the size of the part to be drawn. If you want to draw the whole Image there is a simplified version of this function.

drawImage(myImage, 10, 10, 20, 20, 40, 40);
