SKMatrix44.Preserves2DAxisAlignment(Single) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Determines if transforming an axis-aligned square in 2D by this matrix will produce another 2D, axis-aligned square.
public bool Preserves2DAxisAlignment (float epsilon);
Parameters
- epsilon
- Single
The amount of error to allow for when determining axis-alignment.
Returns
Returns true
if the matrix preserves 2D axis alignment, otherwise false
.
Remarks
If the result is true
, it typically means the matrix is a scale with perhaps a 90-degree rotation. A 3D rotation through 90 degrees into a perpendicular plane collapses a square to a line, but is still considered to be axis-aligned.
