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...

First if you mean the very corner pixel, than that is pixel 0,0 To make all pixels of that color transparent use.. convert image.gif -fill none -draw 'color 0,0 replace' output.gif To replace only pixels of the same color, connected to that pixel that colro use.. convert image.gif -fill none -draw '...

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

There is also info on handling really really really large images
on the IM example page...

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
http://www.cit.gu.edu.au/~anthony/graph ... s/testing/

This information is given on the very top level page of the IM Examples. EG: PC Windows users: All examples are written for use on UNIX, and specifically Linux systems, however with care they should be usable on Windows and in DOS scripts. Caution is recommended however. Window users should specific...

You could just draw the rectange with a 50% transparent white. Current that is specified as -fill '#FFFFFF80' For an example see Annotation Images, Label Overlays... http://www.cit.gu.edu.au/~anthony/graphics/imagick6/annotating/#label_on Their is a request however to allow something like a white_50...

But it is needed for postscript conversion. The PNG was just the output result.

IM montage concatinate does not center align images. Though you can do it without resorting to concatenate mode. EG vertical append centered montage images... -geometry '1x1+0+0<' -tile 1x output.png I have noted this in IM examples at http://www.cit.gu.edu.au/~anthony/graphics/imagick6/montage/#app...

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.
