Hi guys,
I found a bug in the -draw "polyline..." function.
Example:
Code: Select all
convert -size 640x480 xc:white -stroke black -strokewidth 10 -fill transparent -draw "polyline 582,114 582,115 580,118" polyline_error.jpeg
Has anybody an idea or workaround?

What do you think it is doing wrong?
It's also helpful if you state your platform and IM version.

An example of your "bad" results might be useful also. Post it on some free image hosting service and put a link to it here.

Sorry, but I'm a little bit confused now.
I've tried this command on my computer at work with Ubuntu 12.10 and ImageMagick version 6.8.0-4.
Now I've tried it again at my home computer with Ubuntu 12.10 and the same ImageMagick version and the image is ok.
On monday I can post the bad image here.

Hallo again,
I found out, that I've got a self-compiled ImageMagick version at home, because the original version on Ubuntu 12.10 is 6.7.7.
I've compiled the newest ImageMagick version 6.8.2-3 on my work computer and the image looks good.
For the sake of completeness I post the bad image:

polyline has other problems which had been reported a long time ago.
