Convert a Specific PDF Page to an Image in Python
Spire.PDF for Python offers the PdfDocument.SaveAsImage(int pageIndex) method to convert a particular page into an image stream. The stream can be then saved as a JPEG, PNG, BMP or EMF image file. The following are the detailed steps.
- Create a PdfDocument object.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Convert a specific page into an image stream using PdfDocument.SaveAsImage(int pageIndex) method.
- Save the image steam as a JPG file using Stream.Save() method.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF document
pdf.LoadFromFile("template.pdf")
# Convert a specific page to an image
with pdf.SaveAsImage(2) as imageS:
# Save the image as a JPG file
imageS.Save("PageToPNG.jpg")
pdf.Close()
Convert an Entire PDF to Multiple Images in Python
To save each page in a PDF document as a separate image, you just need to put the conversion part inside a loop statement. The following are the detailed steps.
- Create a PdfDocument object.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Loop through the pages in the document and convert each of them into an image stream using PdfDocument.SaveAsImage() method.
- Save the image steam as PNG files using Stream.Save() method.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF document
pdf.LoadFromFile("template.pdf")
# Iterate through all pages in the document
for i in range(pdf.Pages.Count):
# Save each page as an PNG image
fileName = "Output\\ToImage-{0:d}.png".format(i)
with pdf.SaveAsImage(i) as imageS:
imageS.Save(fileName)
pdf.Close()
