We were able to perform the visuals for the last song of the night. It was our first time doing this – it was fun and nerve racking to do. All of the footage and motion was computed and directed in real-time and rendered stereoscopically. Thanks everyone including to Morgan Page & 3dLive for letting us do this.
Okay. So it’s disk cleanup time. Over the years I’ve accumulated a fair amount of images, not all of them have been saved with compression – which vastly reduces their file size.
In my case I’m looking at TIF and SGI files. Many time Flame operators forget to click the ‘compression’ button when they save out these formats due mostly to ignorance. What they don’t realize is that it’s loss-less compression. I digress.
So let’s reclaim disk space! Here is one stab at it using a bash script. Requires imagemagick. This will recursively descend from the current working directory.
*this code could be modified to deal with SGI’s, or targa (TGA) files. Make sure to check that convert’s -compress option is valid for those types!
#!/bin/bash
tifs=$(mktemp)
utifs=$(mktemp)
utifsizes=$(mktemp)
echo "Finding TIF files... (Please wait) > $tifs"
find . -iname "*.tif" -exec du {} \; > $tifs
echo -n "Disk usage of tif files "
awk 'BEGIN { sum = 0 } {sum = sum + $1} END {print sum " MB"}' $tifs
echo "Finding uncompressed TIF files... (Please wait) > $utifs"
cut -f2- $tifs | while read line ; do
identify -quiet -format "image-compression %C %d/%f" "$line" | grep None >> $utifs
done
echo -n "Number of uncompressed TIF files... "
count=$(wc -l $utifs | cut -d' ' -f1)
echo $count
if [ "$count" -ne "0" ] ; then
echo -n "Computing disk space used by uncompressed TIF files... > $utifsizes"
cut -f2- $tifs | while read line ; do
du -m "$line" >> $utifsizes
done
awk 'BEGIN { sum = 0 } {sum = sum + $1} END {print sum " MB"}' $utifsizes
echo "Compressing TIF files... (Please wait) "
cut -d' ' -f3- $utifs | while read line ; do
echo convert -compress lzw \""$line"\" \""$line"\"
convert -quiet -compress lzw "$line" "$line"
done
