DXFontRepository.AddFont(Stream) Method

Loads a font from a stream.

Namespace: DevExpress.Drawing

Assembly: DevExpress.Drawing.v25.2.dll

NuGet Package: DevExpress.Drawing

Declaration

C#

public void AddFont(
    Stream fontStream
)

VB.NET

Public Sub AddFont(
    fontStream As Stream
)

Parameters

Name	Type	Description
fontStream	Stream	A stream from which to load the font.

Remarks

The AddFont method supports the following font formats:

• TrueType fonts (.TTF)

• OpenType fonts that use CFF (Compact Font Format) glyph outlines (.OTF)

• OpenType Font Collections (.TTC, .OTC) that contain multiple fonts in a single file

To avoid excessive layout recalculations, add the required fonts to DXFontRepository before you load a document, report or dashboard that uses these fonts.

Loaded fonts are not saved to the document, report or dashboard. They are used to display, print, or export the document, report or dashboard to PDF.

The code sample below adds custom fonts to DXFontRepository. This example uses the following Google fonts:

• Advent Pro
• Roboto

C#

using DevExpress.Drawing;
using System.IO;
//...

using (FileStream font1 = new FileStream(@"Fonts\advent-pro.regular.ttf", FileMode.Open))
    DXFontRepository.Instance.AddFont(font1);
using (FileStream font2 = new FileStream(@"Fonts\Roboto-Light.ttf", FileMode.Open))
    DXFontRepository.Instance.AddFont(font2);
//...

DXFontRepository.Instance.Dispose();

VB.NET

Imports DevExpress.Drawing
Imports System.IO
'...

Using font1 As New FileStream("Fonts\advent-pro.regular.ttf", FileMode.Open)
    DXFontRepository.Instance.AddFont(font1)
End Using
Using font2 As New FileStream("Fonts\Roboto-Light.ttf", FileMode.Open)
    DXFontRepository.Instance.AddFont(font2)
End Using
'...

DXFontRepository.Instance.Dispose()
