Since I mentioned it in Izobalax's journal here: [link] I decided I should mention it here too. The following example can be used to make a script that will automate resizing for your icon themes. You should use the biggest iconss you have and resize them downwards with it. I don't exactly remember where I found the script, but trust me, this saves alot of time.

Here's the bash script:

#!/bin/bash

for file in `ls -R *.png`
do
FILENAME=`basename $file .png`
EXTENSION=".png"
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/16x16/status/$FILENAME$EXTENSION --export-width=16
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/24x24/status/$FILENAME$EXTENSION --export-width=24
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/32x32/status/$FILENAME$EXTENSION --export-width=32
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/48x48/status/$FILENAME$EXTENSION --export-width=48
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/64x64/status/$FILENAME$EXTENSION --export-width=64
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/72x72/status/$FILENAME$EXTENSION --export-width=72
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/96x96/status/$FILENAME$EXTENSION --export-width=96
inkscape --file="$file" --export-png=/home/thinker/.icons/Amora-Mod/128x128/status/$FILENAME$EXTENSION --export-width=128
done

Now, this script resizes every single icon from my status folder to every other necessary size under it (so scalable with 128, resizes down to 128, 96, 72, 64, 48, 32, 24, and 16). You can also make a big script that does this for every folder all together, so you just need to copy the corresponding lines over and over again and replace "status" to "apps", for example.

If anyone has any questions, just ask and I'll try to answer the best that I can.
