Polygon Tool

ALT-P

Introduction

This tool draws regions with straight edges. It is deprecated in favor of the Spline Tool which can draw straight edged polygons and also curved shapes.

Here are some example polygons (in case you forgot what they look like):

Note that the edges can cross each other. When they do, the Winding Style Parameter comes into play.

Options

The Tool Options Panel allows you to specify:

• Name : Used for the new layer; any number in this field will automatically increment with each layer created

• Layer Type : Whether create Polygon Layer and/or Outline Layer, Advanced Outline Layer, Region Layer, Plant Layer and Curve Gradient Layer layers (Splines)

• Blend Method Parameter : The blending method used to composite on the layers below

• Opacity : Sets the Opacity for new layers. Defaults to 1.00 (Completely opaque)

• Brush Size : Sets the Outline Layer: Outline Width or the size of the gradient (only for Outline Layer, Advanced Outline Layer and Curve Gradient Layer)

• Invert : Whether invert the create(d) layer(s). Is related to his Invert Parameter.

• Feather Parameter : Width of the area to be dissolved at the edge (not for Plant Layer and Curve Gradient Layer)

• Link Origins : Whether Link the Offset of Splines

Usage

Just click over the different corners of the polygon.

To finish the creation of the spline you have different options :

• Click again over the first vertex.

• Using the gear Make Polygon button at the bottom of the Tool Options Panel.

• Select any other tool from the Toolbox Panel.

The Clear Current Polygon button at the bottom of the Tool Options Panel could be used to clear the current polygon.
