Transforming a PDF page typically involves applying various operations to change the appearance or layout of the content on that page. These transformations can include scaling (resizing the page) and translating (moving the content to a different position).

Quickstart: Transform PDF Pages Effortlessly

Learn how to easily transform PDF pages using the IronPDF library in .NET. With just a few lines of code, you can scale and translate page content without affecting the original page dimensions. This quick guide demonstrates how to apply these transformations to enhance your PDF documents seamlessly.

Transform PDF Pages

Two transform features can move and resize the content. This only affects the appearance of the content displayed on the page and does NOT change the physical page dimensions. Let's try the Transform method on a basic PDF document example.

:path=/static-assets/pdf/content-code-examples/how-to/transform-pdf-pages-transform-pdf.cs
using IronPdf;

PdfDocument pdf = PdfDocument.FromFile("basic.pdf");

pdf.Pages[0].Transform(50, 50, 0.8, 0.8);

pdf.SaveAs("transformPage.pdf");

  • Scalable Transformation: This part of the code scales down the PDF content to half its original size by setting the scale factors to 0.5 for both width and height dimensions.
  • Translation Transformation: The content of the PDF page is moved 100 units to the right and 200 units down, effectively repositioning it within the page.
  • Saving the Transformed PDF: After transformations are applied, the document is saved as a new file.
