PDF Viewer for Python Tkinter
!!! ATTENTION !!!
!!! THIS ONLY WORKS FOR PYTHON 2 !!!!
I am currently working on an update for python3
viranthas pypdfocr is not working properly with python 3.
For use with python 2, happily use the version below.
Finally I came to a solution I can work with.
Using pypdfocr and its pypdfocr_gs library I call
pypdfocr.pypdfocr_gs.PyGs({}).make_img_from_pdf(pdf_file)
to retrieve jpg images and then I use PIL to get ImageTk.PhotoImage instances from it and use them in my code.
ImageTk.PhotoImage(_img_file_handle)
Will add a proper example as soon as I can.
Edit:
As promised here comes the code
import pypdfocr.pypdfocr_gs as pdfImg
from PIL import Image, ImageTk
import Tkinter as tk
import ttk
import glob, os
root=tk.Tk()
__f_tmp=glob.glob(pdfImg.PyGs({}).make_img_from_pdf("\tmp\test.pdf")[1])[0]
# ^ this is needed for a "default"-Config
__img=Image.open(__f_tmp)
__tk_img=ImageTk.PhotoImage(__img)
ttk.Label(root, image=__tk_img).grid()
__img.close()
os.remove(__f_tmp)
root.mainloop()
Edit:
Using viranthas pypdfocr version there seems to be a bug inside the handling of Windows 10 and pythons subprocess:
# extract from pypdfocr_gs:
def _run_gs(self, options, output_filename, pdf_filename):
try:
cmd = '%s -q -dNOPAUSE %s -sOutputFile="%s" "%s" -c quit' % (self.binary, options, output_filename, pdf_filename)
logging.info(cmd)
# Change this line for Windows 10:
# out = subprocess.check_output(cmd, shell=True)
out = subprocess.check_output(cmd)
# end of extract
