Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
In IM v6.8.5-0 (on Windows 7), "caption:" clips words where 6.8.4-0 didn't. I don't know if this is a new bug or a fix of an old bug. In other words, I don't know if 6.8.4 or 6.8.5 is correct. Examples:
rem These two clip the long word:
convert -size 50x200 -pointsize 20 caption:"abc defghijklmnop" c1.png
convert -size 50x -pointsize 20 caption:"abc defghijklmnop" c2.png
Its working. ImageMagick only computes splits if height is not defined. We assume the user knows what they are doing if each of width / height / pointsize are defined. This is a similar behavior with labels.
