isIdentity Property

Summary

Gets a value that indicates whether this LeadMatrix is an identity matrix.

Syntax
TypeScript
JavaScript
Object.defineProperty(LeadMatrix.prototype, 'isIdentity', 
	get: function() 
) 
isIdentity: boolean; // read-only

Property Value

true if the LeadMatrix object is an identity matrix; otherwise, it is false. The default is true.

Remarks

An identity matrix has a value of 1 in coefficients [1,1],[2,2],[3,3] and a value of 0 in the rest of the coefficients. This correlates to setting M11 and M22 to 1 and M12, M21, OffsetX, and OffsetY to 0. In an affine matrix, coefficients [3,1],[3,2],[3.3] are implied to always have the values 0,0,1 respectively.

1 0 0
0 1 0
0 0 1

For an identity matrix, the ToString method returns the string "Identity" instead of the coefficients of the LeadMatrix.
