Hi Everyone, I'm having trouble saving plot images with the *Agg backends. I've tried TkAgg, GTKAgg, WXAgg, and get the following error message (here for WXAgg): Do not know how to handle extension *.jpg 14:48:54 Debug e:\Projects\wx2.4\src\msw\app.cpp(439): 'UnregisterClass(canvas)' failed with error 0x00000584 (class still has open windows) WX and GTK backends work. I'm using the precompiled 0.60.2 version of Matplotlib (congratulations on the new release), python 2.3.4, windows XP. I'm calling my program from a DOS prompt to get the error messages, working in non-interactive mode and trying to save the image using the save-button widget. Any suggestions? Thanks, Darren -- Darren S. Dale dd...@co... PGP public key available |

If one doesn't specify an extension, the saved image is of type PNG, which is fine. But specifying a .jpg extension to get a JPEG doesn't work with the Agg backends. |

The agg backend can only save png, ps, eps, and svg. jpeg is available from backend_wx and backend_gtk. Personally, I've never encountered a figure for which jpeg was a better output format than png, which is why I haven't worked to provide a jpeg output to agg, but it would be a good thing to add, at some point.
