EndTop Property
Used in conjunction with the EndLeft, StartLeft and StartTop properties to define the path and extent of the brush evaluation. EndLeft is a percentage.
A Brush defined as StartLeft(0) StartTop(0) EndLeft(100) EndTop(100) will appear to travel diagonally from the top left to the bottom right.
A Brush defined as StartLeft(0) StartTop(0) EndLeft(0) EndTop(100) will appear to travel vertically from the top to the bottom.
A Brush defined as StartLeft(0) StartTop(0) EndLeft(0) EndTop(50) will appear to travel vertically from the top to half way down the control. The Spread property will determine appearance beyond the extent of the start and end coordinates.
This collection of properties define the line along which a gradient color will change. It has StartTop and StartLeft co-ordinates, and EndTop and EndLeft co-ordinates. A StartLeft and StartTop of 0 refer to the top left hand corner of an area, and EndTop and EndLeft of 100 refern to 100% across and down, thus to the bottom right corner of the area.
