PdfCreationOptions.NotEmbeddedFontFamilies Property

Gets or sets a list of font families that are not embedded in a document.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v24.2.Core.dll

NuGet Package: DevExpress.Pdf.Core

#Declaration

public IList<string> NotEmbeddedFontFamilies { get; set; }

#Property Value

Type Description
IList<String>

A string list representing the collection of font families that are not embedded in a document.

#Remarks

Non-embedded fonts can contain only 256 unique Unicode characters each.

Glyph shaping does not work for non-embedded fonts.

The font names can be used with postfixes in the following format: “FontName,Postfix” (e.g., “Arial,Bold”). There are three postfixes: “Bold”, “Italic”, and “BoldItalic”.

If the postfix is specified, only fonts with the corresponding style will not be embedded in a document.

The white spaces in font names are ignored.

#Example

This example shows the PDF Document Creation API that is used to programmatically generate a document layout.

  • The custom DrawGraphics method draws content inside an empty PDF document.
  • The custom AddWatermark method generates a watermark with custom text and adds it to the created PDF document.

When you launch the app, the file is saved to your Documents folder (%userprofile%/Documents).
