Methods' Details |
getContentCanvas
- Description
- Query a render canvas for this sprite's content.
Whatever is rendered to this canvas will become visible on the
screen only after a XSpriteCanvas::updateScreen() call at the
associated sprite canvas. This canvas is not equivalent to the
host canvas of the sprite. At the very least, all output
happens relative to the sprite's upper left corner, i.e. the
origin of the sprite's canvas device coordinate system will
move with the sprite across the screen.
- Returns
- the canvas the sprite content can be rendered into.
