What is CTL?

The Open Group's Complex Text Layout (CTL) pre-structured technology (PST) project integrates the display and editing of complex text languages (e.g. Hebrew, Arabic, Thai, Korean) into the CDE/Motif environment, based on an implementation of the X/Open Portable Layout Services specification. CTL will provide support for composed, context sensitive and intermixed bi-directional characters.

CTL is an implementation of the X/Open Portable Layout Services API with an architecture supporting pluggable locale-specific modules (and LO_LTYPE definitions) for some set of locales.

The CTL PST was sponsored by SunSoft; Silicon Graphics, Inc.; IBM; and Digital Equipment Corporation

The focus areas of the CTL are:

  • CDE now has a single framework to support languages such as Arabic, Thai, and Hebrew.
  • Vendors can easily share support of the Open Group's CTL language-specific implementation provide by other ISVs.
  • The framework will be compliant with future XPG specifications.

Support for Complex Text Layout (CTL) will allow localized software solutions to be provided for where CTL based solutions are the defacto standard and a requirement for doing business (e.g; Middle East, Thailand, North Africa). Significant time-to-market leverage exists for users of Motif with CTL support embedded in it.
