#
- 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
Figure
The figure instance.
- widthscalar
The width of the canvas in logical units
- heightscalar
The height of the canvas in logical units
- dpifloat
The dpi of the canvas
- vector_renderer
RendererBase
An instance of a subclass of
RendererBase
that will be used for the vector drawing.- raster_renderer_class
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.)
- figure
- 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.
