Add support for lines and connector shapes about python-pptx HOT 9 CLOSED

Seconded. This would be an extremely helpful feature.

from python-pptx.

I have python code that generates connector shapes. If it would help you with this library, I can send you a copy.

Sure, want to fork and then send a pull request? I'll be happy to take a look :)

Checking on this one as we need to be able to draw a polygon on a slide (Outlining areas of a picture) and I don't see a way to do this without it.

Thanks!

If a normal-ish polygon will do the trick, you could pick a suitable AutoShape (rectangle, circle, pentagon, etc.) and set its fill to no-fill and set its outline color and width to suit. That would certainly be a lot less work that forming it from individual lines. Note that with adjustment handles you can exercise quite a bit of control over shapes that have them.

Lines/connectors are not on the immediate roadmap, although they are relatively high up in the backlog sequence/priority.

Something like this will work

from pptx import Presentation
from pptx.util import *

from lxml import objectify
from pptx.oxml.ns import nsdecls



title_only_slide_layout = prs.slide_layouts[5]
slide = prs.slides.add_slide(title_only_slide_layout)
shapes = slide.shapes
self._add_line_sp(shapes,2284189,1701577,0,3959671)

    line_tmpl = """

@scanny @thomasysliu are you interested in working on this? I'd be interested in funding it. We have a requirement for loading a networkx json file into a .pptx slide showing nodes and edges. The nodes would be images/icons provided by references in the JSON.

@johnrfrank Yes, we have a mechanism for sponsored features. If you contact me at the email on my profile page https://github.com/scanny if you like and we can set up a quick call.
