Figures 5, 9: Worst-case scenario for glyphs

The paper relies on LaTeX to arrange the individual glyph renderings into one row. Note that my reliance on using a simple shell for all the commands is stretched here, as I essentially want a procedure call, implemented with subworst.txt.

subworst.txt:

SOID -sh $SH -os 1.00 -sc 0.70 0.45 0.19 -p 0.00 0.00 -0.04 \
 | OFF2EPS $FR -o worst-${GL}-1${L}.eps 
SOID -sh $SH -os 1.02 -sc 0.70 0.45 0.30 -p 0.00 0.00 -0.02 \
 | OFF2EPS $FR -o worst-${GL}-2${L}.eps 
SOID -sh $SH -os 1.02 -sc 0.70 0.44 0.44 -p 0.00 0.00 -0.01 \
 | OFF2EPS $FR -o worst-${GL}-3${L}.eps 
SOID -sh $SH -os 1.02 -sc 0.70 0.44 0.51 -p 0.00 0.00 -0.01 \
 | OFF2EPS $FR -o worst-${GL}-4${L}.eps 
SOID -sh $SH -os 1.03 -sc 0.70 0.43 0.60 -p 0.00 0.00  0.01 \
 | OFF2EPS $FR -o worst-${GL}-5${L}.eps 
SOID -sh $SH -os 1.02 -sc 0.70 0.41 0.70 -p 0.00 0.00  0.00 \
 | OFF2EPS $FR -o worst-${GL}-6${L}.eps 
SOID -sh $SH -os 0.99 -sc 0.70 0.39 0.91 -p 0.00 0.00  0.04 \
 | OFF2EPS $FR -o worst-${GL}-7${L}.eps 
SOID -sh $SH -os 0.94 -sc 0.70 0.34 1.16 -p 0.00 0.00  0.10 \
 | OFF2EPS $FR -o worst-${GL}-8${L}.eps

The "-sc" and "-p" parameters were found manually, via trial-and-error, no doubt there is a more mathematical way of doing this.

Then the main commands:

setenv CAM "-up 1 2 0 -rh"

setenv FR "-fr 1.5 1.5 -5.5"
