Interface GraphicsContext

All Known Implementing Classes:

GDXRenderer, Java2DGraphicsContext, TeaGraphicsContext

public interface GraphicsContext

Provides access to the renderer's drawing operations. The renderer only allows drawing operations at the end of a frame updates, when the frame is rendered.

All drawing operations use X and Y coordinates that are relative to the canvas, with the (0, 0) coordinate representing the top left corner. When drawing objects, the X and Y coordinates indicate where the object's center will be drawn. There is no explicit Z coordinate, depth ordering is based on the order in which the graphics are drawn.
