matplotlib.backends.backend_mixed

class matplotlib.backends.backend_mixed. MixedModeRenderer ( figure, width, height, dpi, vector_renderer, raster_renderer_class=None, bbox_inches_restore=None ) [source]

Bases: object

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.

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 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.)

start_rasterizing ( ) [source]

Enter "raster" mode. All subsequent drawing commands (until stop_rasterizing is called) will be drawn with the raster backend.

stop_rasterizing ( ) [source]

Exit "raster" mode. All of the drawing that was done since the last start_rasterizing call will be copied to the vector backend by calling draw_image.
