Properties

AffectsX

#
bool AffectsX { get; }
Gets whether this element will affect the x component of a coordinate.

AffectsY

#
bool AffectsY { get; }

Methods

DistanceTo

#
float DistanceTo(PointF point)
Compute the distance from a point to this snapping element.
Parameters:
point (PointF)Point to test.
Returns: Distance between point and element.

Elements

#
IEnumerable<ISnapElement> Elements(RectangleF region)
Get all the snapping elements that are relevant within the given rectangle.
Parameters:
region (RectangleF)Boundary region.
Returns: All relevant elements within region.

IsInRange

#
bool IsInRange(PointF point)
Gets whether a point is within reach of this snapping element.
Parameters:
point (PointF)Point to test.
Returns: True if the distance from the point to the element is less than or equal to the snapping radius.

Project

#
bool Project(PointF point, out PointF projected, out double x, out double y)
Project a point to this snapping element.
Parameters:
point (PointF)Point to project.
projected (out PointF)Projected point on element.
x (out double)X value of projection.
y (out double)Y value of projection.
