# NAME

PDF::API2::TTF::Cvt_ - Control Value Table in a TrueType font

# DESCRIPTION

This is a minimal class adding nothing beyond a table, but is a repository for cvt type information for those processes brave enough to address hinting.

# INSTANCE VARIABLES

val
| This is an array of CVT values. Thus access to the CVT is via:
        $f->{'cvt_'}{'val'}[$num];

# METHODS

## $t->read

Reads the CVT table into both the tables `' dat'` variable and the `val` array.

## $t->update

Updates the RAM file copy `' dat'` to be the same as the array.

# BUGS

None known
