The whole image should not be needed for a MNP animation, just as the whole image is not needed for a GIF animation. Hmmm convert grf-logo.mng -deconstruct -set delay 20 grf-logo_2.mng Produces a much smaller image, though still larger than GIF. The size may be reduced further by playing with the -q...

I have not seen any such problems like this at all, and I have downloaded quite a few JPEG and PNG images off the net, so they were created in many ways.

The only time I have had major problems with images is for TIFF format, and generating ICO format images.

Not with IM. Also wether you can actually do it at all depends on the IM format. JPG images will probably not be simple, due to its speciallised compression, but if it is posible, remember the pixels may not be exactly the same colors as what you had when you saved the image. JPG is a lossy compress...

Only a rough guess can be extracted by any program, as it isn't stored in the JPEg image itself.

I think identify will report that rough guess

if you don't have a +clone you are NOT using version 6 of IM in which case parenthesis will also not work, and you will be stuck runing lots of separate convert commands creating temproary files and piple lines to pass images between them. See the basics page for details of the major changes and add...

There is something very strange about ICO files, sometimes it works sometimes they don't. Even ICO files generated by other applications have problems.

I have a summery of this bug on the IM example bugs/testing page

I'm not sure. I think Gimp and Photoshop has from special filters for creating news print like screens.

In IM it would be an artistic filter, and I have not even started to explore all those options (it is a masive set).

I suggest you mail cristy with that suggestion.

This -units probelm has come up before, and I am not sure why it isn't a default. Must be a reason though.

I can see what you mean.. the dashed arcs dissappear completely.

This looks like a different problem, though may be related.

I am not sure how to demonstrate this from the command line though as that is the interface I use.
