ViewGetNumPixelsInUnitSquare(Point3d, Boolean) Method

Returns the display pixel density at the specified point for this Viewport object.

Namespace: Teigha.GraphicsSystem
Assembly: TD_Mgd (in TD_Mgd.dll) Version: 24.2.0.0

Syntax

public virtual Point2d GetNumPixelsInUnitSquare(
        Point3d givenWorldpt,
        bool includePerspective
)

Public Overridable Function GetNumPixelsInUnitSquare ( 
        givenWorldpt As Point3d,
        includePerspective As Boolean
) As Point2d

public:
virtual Point2d GetNumPixelsInUnitSquare(
        Point3d givenWorldpt, 
        bool includePerspective
)

abstract GetNumPixelsInUnitSquare : 
        givenWorldpt : Point3d * 
        includePerspective : bool -> Point2d 
override GetNumPixelsInUnitSquare : 
        givenWorldpt : Point3d * 
        includePerspective : bool -> Point2d

Parameters

givenWorldpt Point3d: [in] WCS center of the unit square.
includePerspective Boolean: [in] If true, the pixel density calculation process considers perspective projection.

Return Value

Point2d

Remarks

Pixel density is measured in pixels per WCS unit. This method can be used to determine whether the geometry generated for an object is smaller than the size of a pixel.
