Hello, I just thinkig... Is there a way to apply an effect to inserted images? Say, I need to make a shadow around all of screenshots included, and it is too laborous to apply the shadow to them in an editor just in order to have screenshots changed in next document version. Is think there is a lot of circumstances when some automatic effect can be needed. Best, Vyatcheslav

you should ask yourself, if there is not a simpler way to do so. see http://www.imagemagick.org/Usage/convolve/#shadow_montage best wishes, peter

ImageMagick does support such effects; probably you could update and enhance or at least get inspiration from the degrade module: http://modules.contextgarden.net/t-degrade Greetlings from Lake Constance!

And of course, today you should use rather lua than bash scripting! To use ImageMagick, there is always os.execute(...). Cheers, Peter -- Contact information: http://pmrb.free.fr/contact/
