Declaration

TIEBrushToolInteraction = class(TIECursorToolInteraction);

Description

A class of TIEUserInteraction that controls interaction for the Paint tool (when MouseInteractGeneral is miBrushTool).
This tool allows the user to paint onto the image with a variety of brushes. When used with a tablet/pen, then pressure will affect the brush size and/or opacity.

Note:
◼You can hold down the Shift key to snap the brush position to the axes
◼If you encounter cursor flickering, you should set ImageEnView1.DoubleBuffered := True;
