Improvements and Changes

Glyph Width Updates

Implemented cross-format glyph width update functionality through the unified com.aspose.font.IFontMetrics.setGlyphWidth() API.

This feature allows to modify glyph width in a consistent way regardless of the underlying font format.

Currently supported formats:

• TTF
• CFF (except fonts with stored procedures)
• WOFF / WOFF2
• OpenType(OTF)
• SVG

The following code snippet demonstrates how to set glyph width using the public method IFontMetrics.setGlyphWidth().

Set glyph width using method com.aspose.font.IFontMetrics.setGlyphWidth

import com.aspose.font.*;

            // 1. Open a TrueType font from a file
            Font font = Font.open(FontType.TTF, "MyFont.ttf");

            // 2. Access the public IFontMetrics interface
            IFontMetrics metrics = font.getMetrics();

            //3. Retrieve a glyph identifier for a character
            uint code = 'A';
            GlyphId glyphId = font.getEncoding().decodeToGid(code);

            //4. Change the glyph width
            double newWidth = 600.0; // example width value
            metrics.setGlyphWidth(glyphId, newWidth);

            //5.Verify the change(optional)
            double updatedWidth = metrics.getGlyphWidth(glyphId);
            System.out.println("Updated width for glyph '" + (char)code + "': " + updatedWidth);

            //5. Save the modified font (if you need to persist the change)
            font.save("MyFont_Modified.ttf");

This release of Aspose.Font for Java is a maintenance release which has been migrated from the latest version of Aspose.Font for .NET. It includes all changes from the equivalent .NET version and further improves the overall stability of the API in terms of functionality.
