Starlink::AST::PGPLOT 0.04

Starlink::AST::PGPLOT is a AST wrapper to the PGPLOT library.

SYNOPSIS

use Starlink::AST::PGPLOT
The main methods which need to be registered with the AST package are shown below,
$status = _GFlush();
$status = _GLine( @x, @y );
$status = _GMark( @x, @y, $type );
$status = _GText( $text, $x, $y, $just, $upx, $upy );
( $status, $xb, $yb ) = _GTxExt( $text, $x, $y, $just, $upx, $upy );
( $status, $chv, $chh ) = _GQch();
( $status, $old_value ) = _GAttr( $attr, $value, $prim );
( $status, $alpha, $beta) = _GScales();

This file implements the low level graphics functions required by the rest of AST, by calling suitable PGPLOT functions (the FORTRAN PGPLOT interface is used).

This file can be used as a template for the development of similar modules to support alternative graphics systems.
