Currently the MapnikRasterizer will not render lines/polygons if the output raster dataset exceeds ~32,800 columns - text and points will render normally regardless of the size.

For example, if I try to process a dataset that spans 40000 x 45000 pixels, the output will be missing the rasterized lines past column 32,768.

The current workaround is to use a RasterTiler before the MapnikRasterizer. You can then use a RasterMosaicker following the MapnikRasterizer to combine the tiles into a single mosaicked dataset.
