Installing IronPDF for Python

Before getting started with the code tutorial first let's see how you can Install IronPDF for Python.

First, make sure Python is installed in the system, and you have a good Python compiler in hand like PyCharm, also PIP should be installed to install IronPDF for Python.

1. First, create a new Python Project or open an existing one.

   2. Open the console and run the following command and press enter.

    pip install ironpdf

2. Just like that IronPDF for Python is integrated into your Python Project.

Reading Scanned PDF Files Using IronPDF For Python

In this section, we will see how you can extract text from scanned PDF files using IronPDF.

from ironpdf import *     License.LicenseKey = " Your License Ket "
# Load Scanned PDF document
pdf = PdfDocument.FromFile("C:/Users/buttw/INV_2023_00008.pdf")
# Extract text from PDF document
all_text = pdf.ExtractAllText()
print(all_text)

from ironpdf import *     License.LicenseKey = " Your License Ket "
# Load Scanned PDF document
pdf = PdfDocument.FromFile("C:/Users/buttw/INV_2023_00008.pdf")
# Extract text from PDF document
all_text = pdf.ExtractAllText()
print(all_text)

The above code example extracts text from scanned PDF files. below is the breakdown of the above code.

1. Import the IronPDF Module:

   from ironpdf import *

   from ironpdf import *

   PYTHON

   This line imports the necessary modules and classes from the IronPDF library. The asterisk (*) indicates that all classes and functions from the module should be imported.

2. Set the License Key:

   License.LicenseKey = " Your License Key "

   License.LicenseKey = " Your License Key "

   PYTHON

   This line sets the license key for IronPDF. You need to replace "Your License Key" with the actual license key you obtained from Iron Software.

   The license key is necessary for using IronPDF and is typically provided when you purchase the product.

3. Load a Scanned PDF Document:

   pdf = PdfDocument.FromFile("C:/Users/buttw/INV_2023_00008.pdf")

   pdf = PdfDocument.FromFile("C:/Users/buttw/INV_2023_00008.pdf")

   PYTHON

   This line loads a scanned PDF document located at the specified file path ("C:/Users/buttw/INV_2023_00008.pdf"). The PdfDocument.FromFile method is used to create a PdfDocument object from the given file.

4. Extract Text from PDF Document:

   all_text = pdf.ExtractAllText()

   all_text = pdf.ExtractAllText()

   PYTHON

   This line extracts all text content from the loaded PDF document using the ExtractAllText method from all the pages. The extracting text is then stored in the all_text variable.

5. Print Extracted Text:

   print(all_text)

   print(all_text)

   PYTHON

   Finally, this line prints the extracted text to the console. The all_text variable contains the text content of the scanned PDF document.

Input PDF

Output text
