STEPS

Republishing is separated into 6 steps:

1. Move the book from the webserver to a work directory

1.1 Replacing all spaces with underscores

2. Creating the watermark from the gathered form in Tactical Watermarks

2.1 Create the watermark in pdf with reportlab

2.2 Convert to a png

3. Append the watermark to the pdf

3.1 Burst the pdf cover

3.2 Rotate the watermark with PIL

3.3 Overlay the watermark with PIL

3.4 OCR the new cover

3.5 Resize the OCRed cover to fit the book

3.6 Merge the cover and the pdf into one

4. OCR the pdf if not OCRed already
5. Delete all the unwanted traces
6. Save the file in a directory open to Library Genesis Staff

FLOW

RUN.SH

To activate the stream I use ./run.sh

for i in {1..5}
do
  ./movebookfolder.sh
  ./watermarkformtxt.sh
  ./appendwatermarktopdf.sh
  ./deletetraces.sh
  ./republish.sh
done

1. Moving the book from the webserver to a work place

cd /home/psc/tacticalbooks/republish/
for name in *; do mv "$name" "${name// /_}"; done
cd `ls -td -- /home/psc/tacticalbooks/republish/* | head -n 1`
for name in *; do mv "$name" "${name// /_}"; done
mv `ls -td -- /home/psc/tacticalbooks/republish/* | head -n 1` /home/psc/scripts/autorepublish/inprogress

2. Creating the watermark from the gathered form in Tactical Watermarks

Bash

cd `ls -td -- /home/psc/scripts/autorepublish/inprogress/* | head -n 1`
mv `ls -td -- *.txt | head -n 1` watermark.txt
mv `ls -td -- *.txt | head -n 1` /home/psc/scripts/autorepublish/watermark
cd /home/psc/scripts/autorepublish/watermark
python3 watermark.py
rm watermark.txt
convert -density 300 -trim watermark.pdf -quality 100 watermark.png
mv /home/psc/scripts/autorepublish/watermark/watermark.png `ls -td -- /home/psc/scripts/autorepublish/inprogress/* | head -n 1`

for line in textLines:
    text.textLine(line)

# Draw
pdf.drawText(text)

# Save the pdf
pdf.save()

3. Append the watermark to the pdf

Bash

cd `ls -td -- /home/psc/scripts/autorepublish/inprogress/* | head -n 1`
cp `ls -td -- *.pdf | head -n 1` /home/psc/scripts/autorepublish/overlay
cp `ls -td -- *.png | head -n 1` /home/psc/scripts/autorepublish/overlay
cd /home/psc/scripts/autorepublish/overlay
mv `ls -td -- *.pdf | head -n 1` target.pdf
python3 burstcover.py
python3 rotatelogo.py
python3 overlaylogo.py
tesseract page1.png out pdf
python3 resizecover.py
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=name.pdf cover.pdf target.pdf
var1=`ls -td -- /home/psc/scripts/autorepublish/inprogress/*/*.pdf | head -n 1`
mv name.pdf $var1

3.1 Burst the pdf cover

from pdf2image import convert_from_path

dpi = 300
pdf_file = 'target.pdf'
pages = convert_from_path(pdf_file ,dpi )

page = pages[0]
page.save('page1.png'.format(0), 'PNG')

3.2 Rotate the watermark with PIL

from PIL import Image
import PIL.ImageOps

#open both the watermark
logo = Image.open('watermark.png')

#rotate the watermark
rotatedlogo = logo.rotate(10, expand=True)
rotatedlogo.save('rotated.png')

3.3 Overlay the watermark with PIL

3.4 OCR the new cover

from PIL import Image
import os

filepath = 'page1.png'
basewidth, height = Image.open(filepath).size
basenumber, ext1 = os.path.splitext(str(basewidth*0.6))
base = int(basenumber)

#rescaling the logo
finallogo = Image.open("rotated.png")
wpercent = (base/float(finallogo.size[0]))
hsize = int((float(finallogo.size[1])*float(wpercent)))
finallogo = finallogo.resize((base,hsize), Image.ANTIALIAS)

finallogo.save('rotatedwatermark.png')

background = Image.open("page1.png")
foreground = Image.open('rotatedwatermark.png')

background.paste(foreground, (40, 70), foreground.convert('RGBA'))
background.save("page1.png")

3.5 Resize the OCRed cover to fit the book

from pdfrw import PdfReader
from PIL import Image
import os
from time import sleep
from pdf2image import convert_from_path
import cv2
import numpy as np
from PyPDF2 import PdfFileReader, PdfFileWriter

pdf = PdfReader('target.pdf')
measures = pdf.pages[0].MediaBox
basenumberwidth, ext1 = os.path.splitext(measures[2])
basenumberheight, ext2 = os.path.splitext(measures[3])
basewidth = int(basenumberwidth)
baseheight = int(basenumberheight)
print(basewidth)
print(baseheight)

fileName = ("out.pdf")

pdfFile = PdfFileReader(open(fileName, 'rb'))
# Getting only first page!
newPage = pdfFile.getPage(0)

newHeight = baseheight
newWidth = basewidth

newPage.scaleTo(newWidth, newHeight)

writer = PdfFileWriter()
writer.addPage(newPage)

with open('cover.pdf', 'wb') as f:
    writer.write(f)

4. OCR the pdf if not OCRed already

5. Delete all the unwanted traces

cd /home/psc/scripts/autorepublish/watermark/
rm watermark.pdf
cd /home/psc/scripts/autorepublish/overlay/
rm watermark.png rotated.png rotatedwatermark.png target.pdf cover.pdf out.pdf
now=$(date +%d-%b-%H_%M_%S)
mv page1.png /home/psc/tacticalbooks/covers/"$now".png

6. Save the file in a directory open to Library Genesis Staff

cd `ls -td -- /home/psc/scripts/autorepublish/inprogress/* | head -n 1`
rm watermark.png
mv `ls -td -- /home/psc/scripts/autorepublish/inprogress/*/*.pdf | head -n 1` /home/libgen/books
rm -r `ls -td -- /home/psc/scripts/autorepublish/inprogress/* | head -n 1`
