Using the Region Layer controls

Adjusting the Region Layer values

Using the Region Layer controls

The Controls panel has two different sets of Region Layer controls:

The simple controls have just three presets: Clean, Standard, or Noisy.

The advanced controls have two sliders on the Controls panel: Line Pickup, and Line Growing. You can also alter these values using arrow buttons and/or by typing a value.

These two sets of controls each use a different and sophisticated algorithm; don't assume that simple controls mean a simple process with poor results! Which method is more effective will depend on the style of your drawing. Try both sets of controls to see which is better.

The Default button resets the Region Layer controls to their default setting.

Using the simple controls

For the simple controls, simply choose between Clean, Standard, or Noisy, depending on how clean or dirty your drawing is.

Using the advanced controls

To use the advanced controls, click on the Advanced button. We recommend you then click on the Defaults button, to set the controls to their default values. Adjust the Line Pickup value so there are region boundary lines wherever there are drawn lines in the Trace Layer. Finally, if there are any unwanted extra regions, reduce the Line Growing value to inhibit them. (These extra regions sometimes appear when drawn lines are close together, and the Image Processor tries to create a boundary between them. You can see this best if you have the Trace Layer displayed as well as the Region Layer.)
