composite is nearly deprecated and less functional that convert. See
http://www.imagemagick.org/Usage/compose/#compose
try (unix syntax)
Code: Select all
convert 2388.jpg \( banquan.png -background none -rotate XX \) -gravity center -compose over -composite banquan.png2388_bq.jpg
windows syntax
Code: Select all
convert 2388.jpg ( banquan.png -background none -rotate XX ) -gravity center -compose over -composite banquan.png2388_bq.jpg
Please always provide your IM version and platform when asking questions, since syntax differs. Please read the top most post in this forum at
