geTransformUserPoint

geTransformUserPoint( 
l_point 
l_list 
)
=> l_point / nil 

Description

Transforms a coordinate pair by the displacement and rotation passed in.

For each coordinate pair defined by the first argument, the corresponding coordinate pair in the result is derived by:

• Rotating or reflecting the coordinate pair about the point (0,0).
• Translating the result of the reorientation by the displacement vector.

geTransformUserPoint performs calculations and is not related to any database object. It can be used in calculating, for example, where a certain shape, such as a pin on the master, within an instance of a cell ends up, given the location and orientation of the cell.

Arguments

l_point	Point to be transformed.
l_list	List of the following: displacement vector for the transformation (offset), rotation or reflection for the objects (orientation), and optional magnification. Valid values for rotation and reflection: R90, R180, R270, MX, MY

Value Returned

l_point	A list of points is returned if the transformation occurs.
nil	No transformation occurs.

Examples

geTransformUserPoint((1.5:2.5) list(0:10 "R90")) 

=> (-2.5 11.5)
