SYNOPSIS

DESCRIPTION

ftvalid is an OpenType layout table validator.

This program is part of the FreeType demos package.

OPTIONS

-f index

Select font index (default: 0).

-t validator

Select validator. Available validators are ot, gx, and ckern.

Note that the availability of validators depends on compile-time options of FreeType (this is, whether the modules `otvalid' and `gxvalid' are compiled into the library).

Supported tables in ot validator are BASE, GDEF, GPOS, GSUB, JSTF, and MATH.

Supported tables in gx validator are feat, mort, morx, bsln, just, kern, opbd, trak, prop, and lcar.

Example: -T "feat:morx"

Supported dialects in ckern validator are ms and apple.

-l

List the layout-related SFNT tables available in the font file. The selected validator (with option -t) affects the list.
