ImageMagick Examples Preface and Index
Known and Fixed Bugs Index
These examples are quick tests, with little or no explanation, to check on
whether a specific known, but simple, bug has been fixed or not in the last
version of IM. As such whenever a new release of IM is downloaded, this page
is automatically re-generated to test the current status of the bug in
question.
No short-term bug testing at this time
Long Term Minor Bugs and Problems
These are known bugs, that will probably take some time to figure out and fix.
Semi-transparent, round end caps
Semi-transparent strokes with end caps produce a extra overlay when it
shouldn't.
convert -size 100x60 xc:skyblue \
-fill white -stroke '#0004' -strokewidth 16 \
-draw "stroke-linecap round path 'M 60,30 L -10,30'" \

The line in the middle is the white fill for this single line.
I could not find any other problems for other end caps, or for
round linejoins.
round end caps with stroke greater than 2
With a stroke of 2 this is fine.
convert -size 80x60 xc:white -fill white \
-draw "stroke black stroke-width 2 stroke-linejoin round \
polyline 14,53 30,5 71,14 51,41" draw_line2.png

But with a stroke of 3 it goes wrong.
convert -size 80x60 xc:white -fill white \
-draw "stroke black stroke-width 3 stroke-linejoin round \
polyline 14,53 30,5 71,14 51,41" draw_line3.png

MVG: diagonal lines are too thick!
A slanted diagonal line appears to be a reasonable thickness
convert -size 100x60 xc:skyblue -fill white -stroke black \
-draw "path 'M 10,10 L 90,10 L 90,50 Z'" \

But the line appears to be much thicker when drawn as a dashed line.
convert -size 100x60 xc:skyblue -fill white -stroke black \
-draw "stroke-dasharray 3 3 33 3 3 3 \
path 'M 10,10 L 90,10 L 90,50 Z'" \
