Member Function Documentation

◆ Contains() [1/2]

bool Contains ( double  x,
double  y 
)

Determines if the specified point is contained with this RectD.

Parameters
xX-coordinate of the point to test
yY-coordinate of the point to test
Returns
true of the point defined through the parameters x and y is inside this Rect; false otherwise.

◆ Contains() [2/2]

bool Contains ( Point2Dd  pt)

Check if a point is located inside this RectD.

Parameters
ptPoint to be checked
Returns
true if pt is inside this RectD, false otherwise.

◆ Equals()

override bool Equals ( object  obj)

Tests whether obj is a RectD structure with the same location and size of this RectD structure.

Parameters
objObject to compare to this one.
Returns
true if obj is a RectD and if the borders are equal.

◆ FromLTRB()

static RectD FromLTRB ( double  left,
double  top,
double  right,
double  bottom
