The bug seems to be fixed in upstream version 6.2.5. As a temporary workaround one can replace the third command (which was based on the online documentation for -draw) with
$ convert yellow.png -draw "image SrcOver 0,0 0,0 red.png" total.png to achieve the correct behavior. Regards, Reid -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
