Overview of DTL OTMaster
DTL OTMaster reveals the secrets of your OpenType and TrueType fonts without your having to slog through text dumps or binary code. It makes the editing of tables easy and smooth using its graphical user interface.
Furthermore, it comes with a built-in Glyph Editor for proofing and editing contours or even drawing glyphs from scratch. The kern Table Viewer provides a kerning class editor for proofing and refining the kerning, and the GSUB/GPOS Table Viewer lets you visually test (and in case of GPOS also adjust) these OpenType Layout tables.
One of the most remarkable functions in OTM, is the option to import and export OpenType Layout features files. During import OTM compiles the OpenType Layout features with the AFDKO (Adobe Font Development Kit for OpenType) syntax (.fea) and produces binary OpenType Layout tables.
