A practical guide
Keep the screenshot set together.
- Choose the PNG files and set their page order.
- Use original preparation to preserve transparency, then choose page size and margins.
- Create the PDF and inspect transparent edges and text.
Try this example
Choose three transparent PNG form screenshots in screen order. Keep original preparation, create a three-page PDF and check that transparent margins look right in your PDF viewer.
