This script pro­duces an adver­tis­ing that was pub­lished in neural mag. As usual we start by defin­ing some global variables.

TMPDIR=i/tmp
LOGODIR=i/free/v/logos/layered/chmod+x_logo_100105/
LOGOLIST=$TMPDIR/vektor.list
TEMPTEX=neural.tex
PDFDIR=$TMPDIR
LAYERS=$TMPDIR/layers.list 
PDFS=$TMPDIR/pdfs.list 
OUTPUTDIR=o/free/neural
 
rm $TMPDIR/*

We use a pro­cess­ing sketch that takes a svg file and draws on the path infor­ma­tion given by this file. We define the para­me­ters to exe­cute the pro­cess­ing sketch as usual.

ren­der­ing

The chmod+x logo was sep­a­rated into lay­ers. The pro­cess­ing sketch now runs on every file (=layer) in the direc­tory. The out­put file­names are unique for each file (=layer) so they can be eas­ily sorted and rearranged later on. The pro­cess­ing script is called inside a for–loop, the input file­names are writ­ten into a textfile which is read by pro­cess­ing.

for PDF in `find $LOGODIR -name "*.svg" | sort`
 do
  echo $PDF > $LOGOLIST
  java  -Djava.library.path="$APPDIR" \
        -cp "$LIBS" \
    chmod_x_shodo4neural_02 
 done   

select­ing

Pro­cess­ing has ren­dered ten dif­fer­ent frames for each file/layer and out­put as pdf file. These pdf files get sorted and ref­er­enced in a list.

CNT=0
 
while [ $CNT -lt 10 ]
 do
     ls $PDFDIR/*.pdf | \
     cut -d "_" -f 1  | \
     cut -d "-" -f 1  | \
     sort | uniq      > $LAYERS
     rm $PDFS

I wanted lay­ers to be treated dif­fer­ent. Some to appear more often, and for cer­tain lay­ers only cer­tain frames (egrep '0001|00002|00003').

IMPORTANTLAYERS="5 6 6 2 2 7 7 7 8 8 8"
VIPLAYERS="5 6"
 
COUNT=1
for LAYER in `cat $LAYERS`
 do
     ls $LAYER* | \
     grep -v 00000 | \
     egrep '0001|00002|00003' | \
     rl --count=1 >> $PDFS
 
        for L in $IMPORTANTLAYERS; do
         if [ $COUNT -eq $L ]; then 
 
          ls $LAYER* | grep -v 00000 | rl --count=2 >> $PDFS
 
         fi
        done
        for L in $VIPLAYERS; do
         if [ $COUNT -eq $L ]; then 
 
          echo $PDFDIR/99_`find $PDFDIR -name "${LAYER##*/}*" |\
          grep 00000 |\
          xargs -l basename` >> $PDFS
 
         fi
        done
            COUNT=`expr $COUNT + 1`
 done

lay­out­ing (=overlaying)

Layouting/Overlaying of pdf-files is done with LaTeX. Because some of the LaTeX code needs to be gen­er­ated by a script any­way, I decided to let the script write the whole tex file. Most of the LaTeX code is sta­tic, only a small sec­tion is writ­ten each time, because there need dif­fer­ent graphic files to be ref­er­enced. This is done with a for–loop.

for PDF in `cat $PDFS | sort | sed 's/99_//'`
    do
       echo  "\put(0,0){\graphic{"$PDF"}}"       >> $TEMPTEX
    done

This loop pro­duces the fol­low­ing LaTeX Code:

Finally the gen­er­ated LaTeX-file is com­piled with with pdflatex, given a unique file­name and moved to a directory.

UNIQUE=`date +%s`
pdflatex -output-directory $OUTPUTDIR $TEMPTEX
mv $OUTPUTDIR/${TEMPTEX%%.*}.pdf $OUTPUTDIR/neural--$UNIQUE-$CNT.pdf
rm $TEMPTEX
CNT=`expr $CNT + 1`
 
done
 
exit 0;

The script cre­ates 10 dif­fer­ent pdfs from which one can be selected accord­ing to per­sonal taste.
