This quick tutorial explains how to resize images in PDF using Python. It has details to set the IDE, a list of steps, and a sample code for developing a PDF photo resizer using Python. You will learn various techniques to enhance the process and create the desired output in different ways.

Steps to Resize PDF Picture using Python

1. Set the environment to use Aspose.PDF for Python via .NET to resize images in a PDF
2. Import necessary classes and load the source PDF file into the Document class object
3. Access the first page and fetch the collection of images from it
4. Get the first image in the collection and save it to a memory stream for further processing
5. Remove the original image placement from the page
6. Create an ImageStamp object using the image stream and set the new height and width
7. Set the position of the ImageStamp at the bottom-left corner of the original image
8. Save the image stamp to the page and save the PDF

These steps summarize how to reduce image size in PDF using Python. Load the source PDF file into the Document class object, access the first page using the 1-based index, access the collection of images from the target page, fetch the desired image and save it in a temporary memory stream. Hide the placement of the original image, create an ImageStamp class object, set the original position of the image, set a new size for the image, and save the stamp into the page before saving the PDF.

Code to Resize PDF Photo using Python

The above code demonstrates how to change image size in PDF using Python. Along with changing the size of the image, you may use the ImageStamp to set a new background, opacity, rotate the image, change the zoom level, and quality of the image. You may also add bounds checking to avoid crossing the page margins and change the image type, or compress the image to create a smaller-sized output file.
