#Splitting files
#
#Splitting PDF files with pdftk was an interesting experience. The burst option breaks a PDF into #multiple files -- one file for each page:
#
# To test the conversion try these commands: (I have better luck with TextBridge Conversions)
# convert -monochrome -density 300 pg_0001.pdf pg001.tif
# tesseract pg001.tif pg001 -psm 6
# OR Use Textbridge to convert tif files to TXT as spreadsheet or table
#
#
PAGES=24 # set to the number of PDF pages to process
SOURCE=MOSS22.pdf # set to the file name of the multipage PDF
#OUTPUT=moss22.txt # creates the final "output file"
RESOLUTION=400 # set to the resolution the scanner used (the higher, the better)
#
touch $OUTPUT
for i in `seq 1 $PAGES`; do
convert -monochrome -density $RESOLUTION $SOURCE\[$(($i - 1 ))\] page$i.tif
# tesseract page$i.tif page$i -psm 6
# cat $OUTPUT page$i.txt > temp.txt
# rm $OUTPUT
# rm page$i.tif
# rm page$i.txt
# mv temp.txt $OUTPUT
#
# OR Use Textbridge to convert tif files to TXT as spreadsheet or table
