	double distanceThreshold,
	double minimumLineWeight
)

Public Function GetAnnotAt ( 
	x As Integer,
	y As Integer,
	distanceThreshold As Double,
	minimumLineWeight As Double
) As IAnnot

public:
virtual IAnnot^ GetAnnotAt(
	[InAttribute] int x, 
	[InAttribute] int y, 
	[InAttribute] double distanceThreshold, 
	[InAttribute] double minimumLineWeight
) sealed

function GetAnnotAt(x, y, distanceThreshold, minimumLineWeight);

Parameters

x

Type: SystemInt32
x coordinate of the screen point

y

Type: SystemInt32
y coordinate of the screen point

distanceThreshold

Type: SystemDouble
Maximum distance from the point (x, y) to the annotation for the annot to be considered a hit.

minimumLineWeight

Type: SystemDouble
For very thin lines, it is almost impossible to hit the actual line. This specifies a minimum line thickness (in screen coordinates) for the purpose of calculating whether a point is inside the annotation or not.
