# PDF::API2::Basic::TTF::Anchor(3pm)

Anchor points for GPOS tables

## NAME

PDF::API2::Basic::TTF::Anchor - Anchor points for GPOS tables

## TITLE

PDF::API2::Basic::TTF::Anchor - Anchor points for GPOS tables

## DESCRIPTION

The Anchor defines an anchor point on a glyph providing various information depending on how much is available, including such information as the co-ordinates, a curve point and even device specific modifiers.

## INSTANCE VARIABLES

- x

  XCoordinate of the anchor point

- y

  YCoordinate of the anchor point

- p

  Curve point on the glyph to use as the anchor point

- xdev

  Device table (delta) for the xcoordinate

- ydev

  Device table (delta) for the ycoordinate

- xid

  XIdAnchor for multiple master horizontal metric id

- yid

  YIdAnchor for multiple master vertical metric id

## METHODS

### new

Creates a new Anchor

### read($fh)

Reads the anchor from the given file handle at that point. The file handle is left at an arbitrary read point, usually the end of something!

### out($fh, $style)

Outputs the Anchor to the given file handle at this point also addressing issues of deltas. If `$style` is set, then no output is set to the file handle. The return value is the output string.

### $a-\>out\_xml($context)
