It draws the layer geographic objects in the given canvas using the informed SRS.

The informed bounding box (bbox) is used to constraint the Layer objects to be drawn. The bbox coordinates must be in the Spatial Reference System given by srid.

Parameters
layerThe layer to be rendered.
canvasThe canvas were the layer objects will be drawn.
bboxThe interest area to render the map.
sridThe SRS to be used to draw the layer objects.

Implements te::map::AbstractRenderer.
