Ctor.
public MemoryFontSource(byte[] fontData)
Parameter | Type | Description |
---|---|---|
fontData | Byte[] | Binary font data. |
Examples
Shows how to use a byte array with data from a font file as a font source.
byte[] fontBytes = File.ReadAllBytes(MyDir + "Alte DIN 1451 Mittelschrift.ttf");
MemoryFontSource memoryFontSource = new MemoryFontSource(fontBytes, 0);
Document doc = new Document();
doc.FontSettings = new FontSettings();
doc.FontSettings.SetFontsSources(new FontSourceBase[] {memoryFontSource});
Assert.AreEqual(FontSourceType.MemoryFont, memoryFontSource.Type);
Assert.AreEqual(0, memoryFontSource.Priority);
