The directory whose images (patterns) are being displayed is listed in the lower panel as indicated below. In 
the example below, the path is set to Standard which will display the entire test pattern library and is the default 
path. 

You might wish to change the directory path if you have added your own bitmap patterns and wanted to select 
them without scrolling through the complete list. You may also have created a custom Pattern List using the 

Pattern List Editor

. Refer to 

Pattern List Editor

 for details on creating a custom Pattern List. 

 

You can change the directory path with the directory icon 

. When you select the directory icon a 

dialog box will appear allowing you to select the alternative path such as the User path shown in the dialog box 
below.
