The custom
shape tool allows you to draw a custom shape (polygon) of your choice by setting
vertices. Just click the start point then move the mouse
and click to set the shape.
Right-click the end point to finish. Click and drag points to edit. Right-click
again to apply.
Use the anti-alias mode to enable or disable anti-aliasing. When anti-aliasing is enabled (default); all drawing is done at the sub-pixel level to give you the highest quality results.
