# Font::TTF::Cvt_ - phpMan

## NAME
    [Font::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
