                                           org.opengis.referencing.operation.TransformException

gets a shapefile reader with the custom shaperenderer shape handler.

Parameters:

ds - the datastore used to obtain the reader

bbox - the area, in data coordinates, of the viewed data.

mt - The transform used to transform from data->world coordinates->screen coordinates

hasOpacity - the transform from screen coordinates to world coordinates. Used for decimation.

Returns:

Throws:

java.io.IOException
