o iF@s2ddlZddlmZddlmZGdddZdS)N) RendererAgg)process_figure_for_rasterizingc@s6eZdZdZ  d ddZddZddZd d ZdS) MixedModeRenderera& A helper class to implement a renderer that switches between vector and raster drawing. 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. NcCsV|durt}||_||_||_||_||_d|_d|_||_| |_ ||_ ||_ dS)a* Parameters ---------- figure : `matplotlib.figure.Figure` The figure instance. width : scalar The width of the canvas in logical units height : scalar 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.)
