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.
Moreover, in convert(1) you suggest to "point your browser to file:///usr/share/doc/ImageMagick-6/www/convert.html", but the imagemagick-doc installs the documentation in "/usr/share/doc/imagemagick-doc/www" instead (imagemagick-doc instead of ImageMagick-6).
Now I don't know if these are Ubuntu only related problems, or ImageMagic's.
Further information on the first part of the issue can be found on UnixStackexchange.
Follow up question. Where do I find this information on my system (coming from here)?
-delay {time} Set the time delay (in 1/100th of a second) to pause after drawing the images that are read in or created after this setting has been defined.
You can specify a different scale for the time delay by specifying a 'x' scaling (giving in ticks per second). For example '10x1' is 10, 1 second ticks, while '10x100' is 10, one hundredth of a second ticks.
Basically the 'x' is equivalent to a fraction '/' sign. For example if you specify '1x160' will set a delay that is appropriate for 160 frames per second.
I am aware that online I can find everything.
I am reporting missing local documentation, which seems to be partially also a Debian (and Ubuntu) related problem.
Precisely,
there is no ImageMagick man page -> Debian issue;
command line options descriptions are missing in the local documentation (see "delay {time}" specification) -> ImageMagick's issue.
