patheffects for Line2D objects

_Slavin_Jonathan · December 19, 2011, 9:21pm

Hi,

It seems that patheffects are not supported for Line2D objects currently
- only for Text and Patch objects. Is there any fundamental reason they
couldn't be extended to support Line2D objects? I'm interested in this
because I draw grid lines for some hammer projection plots and those
lines are Line2D objects. For certain images, it'd be nicer to have the
grid lines use patheffects so that any color of the image would still
allow the grid line to show clearly.

Jon

I just opened a pull request that implements the requested feature.

This patch implements path_effects for Line2D objects. Here is a related reques…t on the mailing list http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg22954.html The current change modifies the Line2D class to take a single path_effects argument. However, there are two paths involved with a single Line2D instance. - a path for the line - a path for the marker edge & face And currently, same path_effects is applied to both paths. I'm not sure if there is a need to apply separate path_effects for those two. We may need an optional argument (e.g., marker_path_effects).

If you're familiar with Git, please test it and see if it works for your need.
I believe I will merge this PR to the master branch in a few days
unless there is any objection.

Regards,

-JJ
