Today, I would like to share with you how C# applies a variety of different fonts in PDF documents. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Introduction of dll

Spire.Pdf.dll is introduced in this program, and the introduction method is as follows:

[method 1] install through NuGet.

You can open solution Explorer in Visual Studio, right-click "references", "manage NuGet packages", then search for "Free Spire.PDF" and click "install".

You can also copy the following to the PM console installation:

Install-Package FreeSpire.PDF-Version 7.8.9

[method 2] manually install.

You can download the Free Spire.PDF for .NET package manually, and then extract it to find the Spire.Pdf.dll under the BIN folder. Open solution Explorer in Visual Studio, right-click "reference" and "add reference" to add a reference to the dll file under the local path BIN folder.
