DBMXITS is a slightly altered version of XITS. The line spacing has been changed.

DBMXITS is a Times-like typeface for mathematical and scientific publishing, based on STIX fonts. The main mission of DBMXITS is to provide a version of STIX fonts enhanced with the OpenType MATH table, making it suitable for high quality mathematic typesetting with OpenType math-capable layout systems, like Microsoft Office 2007+, XeTeX and LuaTeX.

DBMXITS fonts are distributed under the Open Font License, version 1.1.

The preferred way for modifying the fonts is by editing the SFD files under sources directory in the source repository, using FontForge. When submitting patches, please make sure they are as clean as possible, avoiding any unrelated or unnecessary changes.

To build the fonts from source you need GNU Make, FontForge Python module, and FontTools.
