class matplotlib.backends.backend_mixed.MixedModeRenderer(figure, width, height, dpi, vector_renderer, raster_renderer_class=None, bbox_inches_restore=None)
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.
The figure instance.
width : scalar
The width of the canvas in logical units
height : scalar
The height of the canvas in logical units
dpi : scalar
The dpi of the canvas
An instance of a subclass of
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.)
Enter “raster” mode. All subsequent drawing commands (until stop_rasterizing is called) will be drawn with the raster backend.
If start_rasterizing is called multiple times before stop_rasterizing is called, this method has no effect.
Exit “raster” mode. All of the drawing that was done since the last start_rasterizing command will be copied to the vector backend by calling draw_image.
If stop_rasterizing is called multiple times before start_rasterizing is called, this method has no effect.
