The tkPDFViewer is python library developed by Roshan Paswan, which allows you to embed the PDF file in your tkinter GUI.

tkpdfviewer's Issues

How to use tkPDFViewer with an application written using grid manager?

Is there a way to use the library with an application written using grid manager?

New Users can use this if getpiximap broken.

Update - I just cloned this, made changes pushed by @brotherrobot, and created a pypi package called tkPDFViewer2. Feel free to download. I can remove this if @Roshanpaswan ever becomes active again.

Deprecation Warning

Hi! I'm encountering two deprecation warnings while using your library:

Deprecation: 'getPixmap' removed from class 'Page' after v1.19 - use 'get_pixmap'.
Deprecation: 'getImageData' removed from class 'Pixmap' after v1.19 - use 'tobytes'

Could you please solve this?

Anyway, thanks for your hard work 💪

Open multiple files

When I try to open multiple files in different ShowPdf instances, I get a concatenation of both documents in both frames. I would expect instead to get each document in a separate frame.

Code to reproduce the issue:

from tkPDFViewer import tkPDFViewer as pdf
from tkinter import Tk

root = Tk()

file1 = "/path/to/first/pdf"
file2 = "/path/to/second/pdf"

viewer1 = pdf.ShowPdf()
pdf_frame1 = viewer1.pdf_view(root, pdf_location=file1, width=150,height=50)
pdf_frame1.pack(side="left")
viewer2 = pdf.ShowPdf()
pdf_frame2 = viewer2.pdf_view(root, pdf_location=file2, width=150,height=50)
pdf_frame2.pack(side="left")
root.mainloop()

I know what is causing the issue (the img_object_li class attribute) and I will work on a fix on my fork of this project.

Hello,
I would like to offer you some improvements

`

class ShowPdf(threading.Thread, Frame):

img_object_li = []

def __init__(self, parent, width=1200, height=600, pdf_location="", bar=True, load="after"):
    threading.Thread.__init__(self)
    Frame.__init__(self, parent, width=width, height=height, bg="white")

    self.__flagKill = False
    self.__flagRefresh = True

    self.pdf_location = pdf_location
    self.bar = bar
    self.load = load

    scroll_y = Scrollbar(self, orient="vertical")
    scroll_x = Scrollbar(self, orient="horizontal")

    scroll_x.pack(fill="x", side="bottom")
    scroll_y.pack(fill="y", side="right")

    self.percentage_load = StringVar()

    if self.bar == True and self.load == "after":
        self.display_msg = Label(self, textvariable=self.percentage_load)
        self.display_msg.pack(pady=10)

        self.loading = Progressbar(self, orient=HORIZONTAL, length=100, mode='determinate')
        self.loading.pack(side=TOP, fill=X)

    self.text = Text(self, yscrollcommand=scroll_y.set, xscrollcommand=scroll_x.set, width=width, height=height)
    self.text.pack(side="left")

    scroll_x.config(command=self.text.xview)
    scroll_y.config(command=self.text.yview)

def run(self):
    while self.__flagKill is False:
        if self.__flagRefresh is True:
            precentage_dicide = 0

            with fitz.open(self.pdf_location) as open_pdf:
                for page in open_pdf:
                    pix = page.getPixmap()
                    pix1 = fitz.Pixmap(pix, 0) if pix.alpha else pix
                    img = pix1.getImageData("ppm")
                    timg = PhotoImage(data=img)
                    self.img_object_li.append(timg)
                    if self.bar == True and self.load == "after":
                        precentage_dicide = precentage_dicide + 1
                        percentage_view = (float(precentage_dicide)/float(len(open_pdf))*float(100))
                        self.loading['value'] = percentage_view
                        self.percentage_load.set(f"Please wait!, your pdf is loading {int(math.floor(percentage_view))}%")
                if self.bar == True and self.load == "after":
                    self.loading.pack_forget()
                    self.display_msg.pack_forget()

            index = 1.0
            self.text.configure(state='normal')
            for i in self.img_object_li:
                self.text.image_create(index, image=i)
                self.text.insert(index, "\n\n")
                self.text.image = i  #Very important, otherwise the thread gets blocked
                index += 1
            self.text.configure(state="disabled")
            self.img_object_li.clear()  #Avoid duplicates
            self.__flagRefresh = False

def refresh(self):
    self.__flagRefresh = True

def stop(self):
    self.__flagKill = True

`

If you want to add a pdf afterwards, you have to make these modifications:

`

            self.text.configure(state='normal')
            for i in self.img_object_li:
                self.text.image_create(END, image=i)
                self.text.insert(END, "\n\n")
                self.text.image = i  #Very important, otherwise the thread gets blocked
            self.text.configure(state="disabled")
            self.img_object_li.clear()  #Avoid duplicates
            self.__flagRefresh = False

def add_pdf(self, pdf_location):
    self.pdf_location = pdf_location
    self.__flagRefresh = True

`

Example of use:

`

self.pdfView = obdoTkShowPDF(self, pdf_location=pathPDF, width=50, height=30)
self.pdfView.grid(row=1, column=1)
self.pdfView.start()
#do stuff
self.pdfView.stop()
self.pdfView.join()

`
