Interface Renderer2D
public interface Renderer2D
Renderer draws a map on behalf on MapPane
. It determines what features to draw,
bounding box, size, and style from the context.

- TODO:
- REVISIT Renderer2D should extend Renderer once Renderer has been
cleaned up.
paint
void paint(Graphics2D graphics,
Rectangle paintArea,
AffineTransform transform)
- Render features based on the
org.geotools.map.LayerList
,
bounding box and Style
specified in
the context.
- Parameters:
graphics
- The graphics handler to draw to.paintArea
- The bounds of the output area in output units (usually pixels).
The upper left corner is (0,0) in most cases. However, a different value
is allowed if some widget area must be preserved, for example a margin on
the left and top size for painting a graduation.transform
- A transform which converts "World coordinates" to output
coordinates.
This transform will be concatenated to the graphics
transform (as of
graphics.transform
(transform)
)
before the rendering take place.
