An example may be a PDF writer, where most things are drawn with PDF vector commands, but some very complex objects, such as quad meshes, are rasterised and then output as images. NcCsN|durt}||_||_||_||_||_d|_||_|j|_||_ ||_ dS)a& Parameters ---------- figure : `~matplotlib.figure.Figure` The figure instance. width : float The width of the canvas in logical units height : float The height of the canvas in logical units dpi : float The dpi of the canvas vector_renderer : `~matplotlib.backend_bases.RendererBase` An instance of a subclass of `~matplotlib.backend_bases.RendererBase` that will be used for the vector drawing. raster_renderer_class : `~matplotlib.backend_bases.RendererBase` The renderer class to use for the raster drawing. If not provided, this will use the Agg backend (which is currently the only viable option anyway.)
