\brief Class for easy calculation and use of patterns
|
||
|
|
|
||
|
|
PatternHandlers are designed specifically for DisplayDriver subclasses.
|
||
|
|
Pattern support can be easily added by setting the pattern to use via
|
||
|
|
SetTarget, and then merely retrieving the value for the coordinates
|
||
|
|
specified.
