MVG -- path closed if joinstyle is "round"

[wolfdieter]

This command generates "bild.gif" with opened triangle:

Code: Select all

convert -size 400x300 xc:wheat\
	-fill white\
	-stroke red\
	-strokewidth 10\
	-draw "stroke-linejoin miter\
		path 'M 10,10 L 50,100 90,10'"\
	bild.gif

If you switch to "stroke-linejoin: round", then the triangle is closed.
This happens also with arbitrary, program-generated bezier paths.
Any workaround known?

(Platform: Ubuntu)

what is the question? how to close a triangle? one solution is to just add another point that is the same as the first. do I misunderstand? see http://www.w3.org/TR/SVG/ or http://www.imagemagick.org/script/magic ... aphics.php

To close the path add a 'z' to the end of the SVG path string...

Code: Select all

 convert -size 120x120 xc:wheat   -fill white   -stroke red   -strokewidth 10  \
      -draw "stroke-linejoin round  path 'M 10,10 L 50,100 90,10 z'" \
       bild_closed.gif

that produces a nice closed figure with rounded ends. The third line being provided by the 'z'.


What is NOT correct is that your code draws three lines when only two were specified
and no 'closer was given!!!!!!

Code: Select all

  convert -size 120x120 xc:wheat   -fill white   -stroke red   -strokewidth 10  \
      -draw "stroke-linejoin round  path 'M 10,10 L 50,100 90,10'" \
       bild.gif

THIS IS A BUG -- three lines draw but only two specified.


This may also be related to a bug previously reported but unfixed.
