NAME

Prima::Drawable::Antialias - alternative API for antialiased shapes

DESCRIPTION

Prima offers drawing antialiased lines and shapes, which is rather slow but provides better visual feedback.

The module augments the "Prima::Drawable" drawing functionality by adding the "new_aa_surface" function, which features two plotting methods, "polyline" and "fillpoly", identical to the ones in "Prima::Drawable".

The emulation method in the module used to be the backend and the only implementation of antialiased shapes, but as Prima now supports that internally, this module is not used anymore. It is still functional though and can be used as an alternative.

SYNOPSIS

        $canvas-> new_aa_surface-> polyline([0, 0, 100, 100]);
        $canvas-> new_path(subpixel => 1)-> ellipse(100,100,100)->fill;

API

Methods

Creates a new AA surface object. The object is cheap to keep and reuse.

Plots an antialiased polyline. The following properties from the $CANVAS are respected: color, backColor, linePattern, lineWidth, lineEnd, lineJoin, miterLimit, rop2
