Hi, An idea to test the final output: # Create PDFs for all tests. cd $REGRESSION for i in *.tex; do context-beta $i done # Convert all PDF pages to images. for i in *.pdf; do convert $i $(basename $i .pdf)%0d.png done # Note any differences between images. for i in *.png; do if diff $i $ORIGINAL/$i >/dev/null ; then echo "pass" else echo "fail" > $i.log fi done
