How to set single font in PDF using C# and .NET
Working with PDF documents in .NET applications is becoming increasingly popular. One popular tool for this purpose is the component PDF Metamorphosis .NET from SautinSoft API — a powerful and flexible component that allows you to convert, edit, and create PDF files programmatically.
One of the most common tasks in automated PDF processing is the need to set a single font for the entire document. This is important for consistent design, eliminating compatibility issues, and improving the readability of the resulting file.
Setting a single font is the process of programmatically specifying a font that will be used to display all text elements in a PDF document, regardless of the original text sources or default settings.
Advantages of using this code:
- Ensures a consistent visual style for the document.
- Improves readability through appropriate font selection.
- Unify the design of reports, forms, and emails automatically.
- Provides support for languages and characters that use specialized fonts.
An interesting aspect: automatic insertion of uniform fonts also helps when generating multilingual documents, ensuring support for all necessary characters if the correct font is selected.
