Major Features

Added support for combining characters from different fonts of Compact Font Format (CFF). Current functionality for combining CFF fonts is limited in that the use of compound glyphs (glyphs that require subroutines to draw themselves) is not supported. Only glyphs that don’t reference subroutines can be combined into a resultant font.

Next code snippets show how to merge glyphs from 2 CFF fonts.

Combining fonts using object of type Aspose.Font.Common_FontMerger.FontCharactersMerger

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

            TextUtilsFactory factory = new TextUtilsFactory();
            // Open primary CFF font
            string fontPath = Path.Combine(DataDir, "font1.cff");
            FontDefinition fontDefinition = new FontDefinition(FontType.CFF, new FontFileDefinition(new FileSystemStreamSource(fontPath)));
            Font font1 = Font.Open(fontDefinition);

            // Open secondary CFF font
            fontPath = Path.Combine(DataDir, "font2.cff");
            fontDefinition = new FontDefinition(FontType.CFF, new FontFileDefinition(new FileSystemStreamSource(fontPath)));
            Font font2 = Font.Open(fontDefinition);

            GlyphId[] font1Glyphs = new GlyphId[]
            {
                new GlyphStringId("m"),
                new GlyphStringId("n"),

            GlyphId[] font2Glyphs = new GlyphId[]
            {
                new GlyphStringId("A"),
                new GlyphStringId("Z"),
            };

            FontCharactersMerger merger = factory.GetFontCharactersMerger(font1, font2, FontType.CFF);
            CffFont resFont = merger.MergeFonts(font1Glyphs, font2Glyphs, "CombinedFont")
                as CffFont;
            // Output settings
            string outPath = Path.Combine(OutputDir, "CombinedFont.cff");
            using (FileStream outStream = File.Create(outPath))
                resFont.Save(outStream);
