DTL OTMaster for macOS (10 and higher) is an extremely powerful tool for extensive editing of TrueType and CFF/TTF-flavored OpenType fonts. The many sophisticated functions include the adding and editing of glyphs, the revision of (naming) tables, consistency-checking, and the detailed display, import (including subsetting), and export of OpenType Layout features.
The discount for students amounts 50% on the standard end-user price.
Note that these orders are handled manually, which could result in a somewhat delayed delivery, and that proof of registration as student is required.
DTL OTMaster licensees can upgrade from any older full OTM versions for macOS to version 8.9 here. Those who purchased a license for the previous version (7.9) before 14 March 2022 are eligible for a free upgrade: in that case, please contact DTL.
