=== Manually Convert to png/eps for one xmgrace file===
Add this to the end of the xmgrace file
For PNG
<pre>
#Print out to
@PRINT TO "/sbinlab2/tlinnet/output.png"
@HARDCOPY DEVICE "PNG"
@DEVICE "PNG" FONT ANTIALIASING on
# Make white background transparent
#@DEVICE "PNG" OP "transparent:on"
@DEVICE "PNG" OP "compression:9"
@PRINT
</pre>
For EPS
<pre>
#Print out to
@PRINT TO "/sbinlab2/tlinnet/output.eps"
@HARDCOPY DEVICE "EPS"
@DEVICE "EPS" OP "level2"
@PRINT
</pre>
Then issue an "HARDCOPY" with xmgrace
xmgrace -hardcopy xmgracefile.agr
== In bash ==
bash ;
for agr in `ls *.agr`;do bn=`basename ${agr} .agr`;gracebat ${agr} -hdevice PNG -printfile ${bn}.png;done
== Script to make both png and eps for a folder with xmgrace files ==
<source lang="bash">
#!/bin/bash
for gracefile in *.agr; do
filename=$(basename "$gracefile")
extension="${filename##*.}"
filename="${filename%.*}"
TMPPNG=${filename}_png.tmp
cat $gracefile > $TMPPNG
echo "#Print out to" >> $TMPPNG
echo '@PRINT TO "'"${PWD}/${filename}.png"'"' >> $TMPPNG
echo '@HARDCOPY DEVICE "PNG"' >> $TMPPNG
echo '@DEVICE "PNG" FONT ANTIALIASING on' >> $TMPPNG
echo '# Make white background transparent' >> $TMPPNG
echo '#@DEVICE "PNG" OP "transparent:on"' >> $TMPPNG
echo '@DEVICE "PNG" OP "compression:9"' >> $TMPPNG
echo '@PRINT' >> $TMPPNG
xmgrace -hardcopy $TMPPNG
TMPEPS=${filename}_eps.tmp
cat $gracefile > $TMPEPS
echo "#Print out to" >> $TMPEPS
echo '@PRINT TO "'"${PWD}/${filename}.eps"'"' >> $TMPEPS
echo '@HARDCOPY DEVICE "EPS"' >> $TMPEPS
echo '@DEVICE "EPS" OP "level2"' >> $TMPEPS
echo '@PRINT' >> $TMPEPS
xmgrace -hardcopy $TMPEPS
echo "$filename $extension"
#eps2png -resolution 200 $TMPEPS
#epstopdf $TMPEPS
done
</source>
== Batch eps to PNG/PDF conversion ==
<pre>
bash ;
for epsfile in *.eps; do eps2png -resolution 200 $epsfile; epstopdf $epsfile; echo "Making pdf/png: $epsfile"; done
</pre>
