Matrix.UnTransform
Matrix.UnTransform method
Transforms back x1 and y1 and returns x and y before the matrix transformation using the following formula: x = (D * x1 - C * y1 + C * F) / (A * D - C * B) y = (A * y1 - B * x1 + B * E) / (A * D - C * B).
public void UnTransform(double x1, double y1, out double x, out double y)
| Parameter | Type | Description |
|---|---|---|
| x1 | Double | Input X coordinate |
| y1 | Double | Input Y coordinate |
| x | Double& | Output X coordinate |
| y | Double& | Output Y coordinate |
