Usage

import gradio as gr
from gradio_simpletextextractfrompdf import SimpleTextExtractFromPDF

def first_200_chars(text):
    return text[:200]


demo = gr.Interface(
    fn=first_200_chars,
    inputs=SimpleTextExtractFromPDF(),
    outputs=gr.Textbox(label="First 200 characters of the extracted text"),

## Component Description
This space is to demo the usage of the SimpleTextExtractFromPDF component.
This component provides a simple interface to extract text from a PDF file. The extracted text can be submitted as a string input to a function for further processing.
- **Text Extraction Only:** Only the text content is extracted from the PDF. Images and table structures are not preserved.
- **Flexible Upload Options:** Users can upload a PDF file from their device or provide a URL to the PDF.
- **Input Component:** The component is primarily designed to be used as an input, allowing users to submit the extracted text to other functions.
- **Output Display:** When used as an output component, the extracted string content is displayed in a textarea.
The demo app here uses the SimpleTextExtractFromPDF component as an input component to extract the text from a PDF file and then show the first 200 characters of the extracted text.

Events

User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

• When used as an Input, the component only impacts the input signature of the user function.
• When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

• As output: Is passed, passes the extracted text into the function - string.
• As input: Should return, expects a {string} returned from the function and sets component value to it.

def predict(
    value: str | None
) -> str | None:
    return value
