I'm trying to create an expander for each page in a PDF, but I'm unable to achieve this using the following code. Can you help me?
for page in range(1, get_page_count(ss.pdf_ref.getvalue())+1):
page_expander = st.expander(f"Page {page}", expanded=False)
page_expander.write(pdf_viewer(
input=ss.bytes_data, pages_to_render=[1], key=f"pdf_viewer_{page}"
))

[lfoppiano]

What is the issue?

have you tried adding the width when you call the pdfviewer?

[lfoppiano]

you cannot write the pdf_viewer in the expander, maybe you can try with

with st.expander....: 
     pdf_viewer(.....)

[drnihalmehta]

Great component. However, the scroll_to_page doesn't work when height is specified.
Is there any way to scroll to a page when height and width are specified?
Thank you.
Nihal

hi @drnihalmehta, can you share me the code you're using where the scroll_to_page does not work?

Alternatively you can avoid specifying the height and wrap the component into a st.container:

with st.container(height=xyz):
   pdf_viewer(....

[lfoppiano]

@drnihalmehta is it working?

[drnihalmehta]

Hi Luca, I’ll try wrapping within container. Here’s my test code: import streamlit as st from streamlit_pdf_viewer import pdf_viewer # Path to the PDF file folder = "pdfs" filename = "77_yr_breathing_swallowing_difficulty.pdf" pdf_path = f"{folder}/{filename}" # Streamlit app title st.title("PDF Viewer - Using Binary Data") st.write(f"{pdf_path}") # Read the PDF as binary data try: with open(pdf_path, "rb") as pdf_file: pdf_bytes = pdf_file.read() # Pass the binary data directly to pdf_viewer # pdf_viewer(pdf_bytes, scroll_to_page=3, width=700, height=700) except FileNotFoundError: st.error(f"File not found: {pdf_path}") Thanks and best regards, Nihal

Sorry can't you please take some time to format it properly? I can't read it

[drnihalmehta]

Ok. I’ll send you the .py file itself shortly where it’s properly formatted. I cut and pasted into the email and it’s showing up nicely on my end. Sorry about that. Thanks and best regards, Nihal

Here's the sample test file I'm using. Also, it doesn't work when using a URL for the location of the PDF location. Both cases are in this file. Thanks for your help. Thanks and best regards, Nihal Nihal J. Mehta, Ph.D. ***@***.***

[lfoppiano]

URL location is not supported, it's well explained in the documentation.

I could not see the code. Please paste it with markdown directly in github instead of answering by email.

[drnihalmehta]

Here is the code. Thanks again.

import streamlit as st
from streamlit_pdf_viewer import pdf_viewer

# Path to the PDF file
folder = "pdfs"
filename = "test.pdf"
pdf_path = f"{folder}/{filename}"

# Streamlit app title
st.title("PDF Viewer - Using Binary Data")
st.write(f"{pdf_path}")
# Read the PDF as binary data
try:
    with open(pdf_path, "rb") as pdf_file:
        pdf_bytes = pdf_file.read()
        pdf_viewer(pdf_bytes, scroll_to_page=3)
  
except FileNotFoundError:
    st.error(f"File not found: {pdf_path}")

[drnihalmehta]

I got it to work using st.container as you suggested. Thanks and best regards, Nihal

Hi, I am trying to render a pdf and scroll to a specific page.
The pdf is shown properly but the scroll action is not happening.
This is my code:

if st.session_state['references']:
        for i, source in enumerate(st.session_state['references']):
            if st.button(f"{source['file_name']}"):
                # Fetch and display the PDF
                #
                modal = Modal(key = "modal key", title=f"""{source['file_name']}
                Page of Interest: {source['page']}""" , max_width=1000)
                with modal.container():
                    pdf_viewer(get_signed_url(source["url"], url, headers), width=1000, height=1000, scroll_to_page=int(source["page"]))

I also tried without Modal, but it's still the same.
I noticed that if I resize the browser Windows it actually scrolls down to the desired page.
How can I fix it?

[lfoppiano]

It's probably a bug, we need to investigate, if you use version 0.0.18 it should work, see another report here #83
