Summary
Hey,
while investigating possibilities forsvg exports withEOmaps I realized that theFigureCanvasSVG class does not expose the renderer via a.get_renderer() method but initializes the renderer in.pring_svg().
matplotlib/lib/matplotlib/backends/backend_svg.py
Lines 1330 to 1338 in2f778fd
| dpi=self.figure.dpi | |
| self.figure.dpi=72 | |
| width,height=self.figure.get_size_inches() | |
| w,h=width*72,height*72 | |
| renderer=MixedModeRenderer( | |
| self.figure,width,height,dpi, | |
| RendererSVG(w,h,fh,image_dpi=dpi,metadata=metadata), | |
| bbox_inches_restore=bbox_inches_restore) | |
| self.figure.draw(renderer) |
Is this intentional or is this a API inconsistency that should be fixed?
- The same is also true for the
pdfbackend
Proposed fix
Implement.get_renderer() similar to theagg backend:
matplotlib/lib/matplotlib/backends/backend_agg.py
Lines 406 to 413 in2f778fd
| defget_renderer(self): | |
| w,h=self.figure.bbox.size | |
| key=w,h,self.figure.dpi | |
| reuse_renderer= (self._lastKey==key) | |
| ifnotreuse_renderer: | |
| self.renderer=RendererAgg(w,h,self.figure.dpi) | |
| self._lastKey=key | |
| returnself.renderer |
