Legacy ImageMagick Discussions Archive

Cheese(https://wiki.gnome.org/Apps/Cheese) is a gnome software for webcams. It has some interesting effects including the "dice" effect. Is there something similar in IM?

I tried looking for something similar in imagemagick to apply on already captured images but did not find it.

Following your link did not take me to any examples or descriptions of those "interesting effects".

I think I found some examples on Google images and I would say you will have to write your own Imagemagick code for most of the effects.

Some of the simpler effects are built into Imagemagick; see this page

I do not know what effects are provided by cheese. Perhaps you could provide a link to some examples.

In the meantime, if you are on Linux, Mac OSX, Windows w/Cygwin or Windows 10, see my bash unix imagemagick scripts at the link below.

EDIT: OK, I found some similar examples here http://effectv.sourceforge.net/

Here is some Unix-based code to produce the dice effect. It is a bit slow. It took about 15s on my Mac Mini INTEL duo-core vintage 2010.

I will make a formal script for this shortly.

Wow, looks great,

Thanks
