OpenType Layout Features - Introduction
OpenType Layout Features can be used to extend the functionality of fonts and create advanced typographic features and add additional capabilities such as ligatures, alternate glyphs, two-dimensional glyph positioning, specific functionality for different scripts and languages and much more.
When a font is opened, FontCreator will process all supported features in the font and split them up into two separate parts. The first part, the glyph substitutions, will be decompiled into a script that can be edited using the built-in script editor. The second part, the glyph positioning, will be processed to make them visually editable in the OpenType Designer.
If the font you're opening contains Microsoft VOLT project data for OpenType Layout Features, you will be asked if you want to convert this into a FontCreator project. If you choose not to use Microsoft VOLT project data, the binary OpenType Layout Features (GPOS, GSUB, and GDEF tables) will be used instead. You can also import Microsoft VOLT projects later through the OpenType Designer.
Note: Microsoft VOLT project conversion and importing is only available in the Professional edition of FontCreator and some features are not supported.
