Quiet Gimp script to make screenshots

[Gerhard Kulzer]

As manual writers we generate a lot of nice screenshots, a task which can be
quite tedious. To make life a (little) bit easier I updated my Gimp script-fu
to this:

http://digikam3rdparty.free.fr/Tools/kde-screenshot-dropshadow.scm

The script creates a dropshadow conforming to KDE standard. I runs without
dialog and flattens the layers at the end. So the only action it to call it
(from 'Script-Fu'->Utils) and save the screenshot.

This is an update of my previous scripts, which it replaces. It runs fine on
Gimp 2.3.14 and should be backwards compatible at least down to Gimp 2.0
(because the parser of the recent version is stricter)

And, since I'm at it...
The following command compresses the produced PNG file considerably (that's
nice for smaller packages) without visible quality loss:

$ pngnq -s 3 ./*.png && optipng *-nq8.png && rename -f s/-nq8\.png/.png/
*-nq8.png
Just run it in the screenshot directory from a shell.

Of course you need to have optipng and pngnq installed.

Regards
Gerhard

P.S.
Project: shell script using Imagemagick with optipng to do it all at once
without Gimp

I wrote IM script for that long time ago. Should be in archives of the
list.

OK, found it. Looks like -fx changed between 6.2 and 6.3, after
necessary fixes it is here:

Commented version is for images which don't require 1pixel frame around
them, I use it rarely and not useful for Digikam manual photos.

I'm still stuck with 6.2.4 (Debian experimental). I guess that's the problem.
Will try to upgrade.

Thanks Mikolaj

Strange. To make it work with 6.3 I had only slightly change argument
of -fx option. -draw worked as it should.

Another idea - maybe file name is a problem (space, special character,
etc.)? Try it with asdf.png ;)

BTW - in 6.3 you can make it in one line:

convert from.png -bordercolor black -border 1x1 \
        \( +clone -background black -shadow 80x3+7+7 \) \
        +swap -background none -mosaic to.png

A little bug corrected in my gimp script: the last command must be 'merge
layers' and not 'flatten layers'.

The online script is corrected.
