| LeadMatrix | An identity matrix. |
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.
