Python3: Add a line to to a slide
New here? Learn about Bountify and follow @bountify to get notified of new bounties! x

Looking for a simple solution for adding a line to power point slide using the current pptx library.
Must be able to:

1) set color,

2) set line width,

3) set transparency,

4) set line end style,

5) set positions

Something like:

from pptx import Presentation

prs = Presentation("template_Fred.pptx")

line = shape.line

line.color.rgb = RGBColor(255, 30, 100).

line.left = Inches(1).

....# set other stuff....

prs.save('Fred Clone.pptx')

what do you mean by line end style?

Example of adding line:

from pptx.enum.shapes import MSO_CONNECTOR, MSO_SHAPE
from pptx.oxml.xmlchemy import OxmlElement
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor

def SubElement(parent, tagname, **kwargs):
  element = OxmlElement(tagname)
  element.attrib.update(kwargs)
  parent.append(element)
  return element

def _set_shape_transparency(shape, alpha):
  """ Set the transparency (alpha) of a shape"""
  ts = shape.fill._xPr.solidFill
  sF = ts.get_or_change_to_srgbClr()
  sE = SubElement(sF, 'a:alpha', val=str(int(alpha * 100000)))

prs = Presentation()

slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(slide_layout)

shapes = slide.shapes

# position: top, left, width, height
line = shapes.add_connector(MSO_CONNECTOR.STRAIGHT, Inches(4), Inches(2), Inches(1), Inches(7))
# set solid fill
line.line.fill.solid()
# set red color
line.line.fill.fore_color.rgb = RGBColor.from_string("FF0000")
# set width to 10pt
line.line.width = Pt(10)
# set transparency
_set_shape_transparency(line.line, 0.35) # alpha can be any value starting from 0.0 to 1.0

prs.save('example.pptx')

Needs to demonstrate how to change the other attributes: color, thickness/width....
