Thread: [Matplotlib-users] [matplotlib-users] Is it possible to set .pdf as defaut when saving an image?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Is it possible to set the extension .pdf as defaut when I save an
image using the matplotlib bar. My coworkers are always saving the
image in png and it's really ugly!

Thx,

Fab

Interesting request.  Looking through the backends, it appears that only
the Cairo backend currently supports a configurable rcParam for the default
filetype ('cairo.format').  All backends implement a
"get_default_filetype()" method for their canvases, but most of them have
that default hard-coded as "png".  This really only makes sense for
backends like agg, pdf, ps and such.

Devs - Maybe we should consider fixing this for the non-fileformat specific
backends?  Do we want an rcParam for each backend? Or a single rcParam for
default filetypes and deprecate 'cairo.format'?

Cheers!

I would definitely lean toward the latter -- unify it under a single 
rcParam.

Sorry for posting to an old thread, but I just submitted a pull request that 
implements this, AFAICT:
