Getting Started

Are you ready to give Aspose.Font for .NET a try? Simply execute Install-Package Aspose.Font from Package Manager Console in Visual Studio to fetch the NuGet package. If you already have Aspose.Font for .NET and want to upgrade the version, please execute Update-Package Aspose.Font to get the latest version.

Loading of font with TrueType format (.ttf)

using Aspose.Font;
using Aspose.Font.Sources;

// Font file name with the full path
string fontPath = Path.Combine(DataDir, "Montserrat-Regular.ttf");

// Initialize FontFileDefinition based on FileSystemStreamSource object, set fileExtension to "ttf" 
FontFileDefinition fileDef = new FontFileDefinition("ttf", new FileSystemStreamSource(fontPath));

// Initialize FontDefinition using just created FontFileDefinition object, passing TTF as the FontType value
FontDefinition fontDef = new FontDefinition(FontType.TTF, fileDef);

// Load the font
Font font = Font.Open(fontDef);

Extracting font name, font family

using Aspose.Font;

//Reference to font object loaded from some source
Font font;
string fontName = font.FontName;
string fontFamily = font.FontFamily;

Convert TTF to WOFF2

using Aspose.Font.Sources;
using System.IO;

// Open TTF font
string fontPath = Path.Combine(DataDir, "Montserrat-Regular.ttf");
FontDefinition fontDefinition = new FontDefinition(FontType.TTF, new FontFileDefinition(new FileSystemStreamSource(fontPath)));
Font font = Font.Open(fontDefinition);

// Write the output settings for the WOFF2 format
string outPath = Path.Combine(OutputDir, "out.woff2");
FileStream outStream = File.Create(outPath);

// Make conversion from TTF to WOFF2 and save the result using SaveToFormat() method of the base abstract Font class instance
font.SaveToFormat(outStream, FontSavingFormats.WOFF2);

Render text

using System.IO;
using Aspose.Font;
using Aspose.Font.Renderers;

//Reference to font object loaded from some source
Font font;
//Text to render using the specified font
string text = "Hello world";
//Set font size to 12
using (Stream st = RenderingUtils.DrawText(font, text, 12))
{
	//Save rendered text to the file
	byte[] buff = new byte[st.Length];
	st.Read(buff);	
	File.WriteAllBytes("Text.png", buff);
}                        

Generate TrueType font

using Aspose.Font.Ttf;
using Aspose.Font.TtfHelpers;

// Original font to take glyphs from
TtfFont srcFont;

//To create a font we can use functionality of the IFontCharactersMerger interface.
//The IFontCharactersMerger.MergeFonts() method is designed to create a font as a result of merging two fonts.
//It takes two arrays of glyphs or character codes and puts into resultant font only glyphs from these arrays.
//But we can use a trick by passing two references on same font and provide only single array of character codes.

IFontCharactersMerger merger = HelpersFactory.GetFontCharactersMerger(srcFont, srcFont);

TtfFont destFont = merger.MergeFonts(new uint[] { 'a', 'c', 'e' }, new uint[0], "TestFont");

//Save resultant font
destFont.Save("TestFont.ttf");
