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
