Description

Specify rotation center to the GraphObject and rotate

Syntax

BOOL    Rotate( double dAngle, point * ptCenter, BOOL bUndo = FALSE )

Parameters

dAngle: [input] Rotation angle
ptCenter: [input] a point object to specify rotation center's x y coordinates in pixel
bUndo: [input] set undoable

Return

TRUE for success

Examples

EX1

// new Graph window, add a rectangle object, object name is Rect
// set rotation center to (2000,3000) and rotation angle 45: test_rotate("Rect", 2000, 3000, 45)
// set rotation center to top left corner and rotation angle -15:  test_rotate("Rect", 0, 0, -15)
