Viewport Class
This class represents the view characteristics of the current viewport within the ODA Platform vectorization framework. Client code can query this information to generate the correct viewport-dependent geometric representation for an object.

Public property AutoDelete Property that indicates whether the object should be automatically deleted by the Garbage Collector.
(Inherited from DisposableWrapper)
Public property CameraLocation Property that represents the WCS camera (eye) location for this Viewport object.
Public property CameraTarget Property that represents the WCS camera target for this Viewport object.
Public property CameraUpVector Property that represents the WCS camera "up" vector for this Viewport object.
Public property DeviceContextViewportCorners Property that represents the device context viewport corners that are used to position the geometry (such as icons) that remain in a fixed position or fixed size in the viewport's display.
Public property EyeToModelTransform Property that represents the transformation matrix from EyeSpace to ModelSpace for this Viewport object.
Public property EyeToWorldTransform Property that represents transformation matrix from EyeSpace to WCS for this Viewport object.
Public property FrontAndBackClipping Property that represents parameters that indicate whether front and back clipping is enabled, together with front and back clipping distance information.
Public property IsDisposed Property that indicates whether pointer to native code unmanaged object == IntPtr::Zero.
(Inherited from DisposableWrapper)
Public property IsPerspective Property that indicates whether perspective mode is turned on for this viewport.
Public property LinetypeGenerationCriteria Property that represents the value below which linetype generation is not used.
Public property LinetypeScaleMultiplier Property that represents multiplier that is used to scale all linetypes in this Viewport object.
Public property ModelToEyeTransform Property that represents transformation matrix from ModelSpace to EyeSpace for this Viewport object.
Public property UnmanagedObject Property that represents a pointer to an unmanaged object.
(Inherited from DisposableWrapper)
Public property ViewDirection Property that represents the vector from the camera target to the camera location.
Public property ViewportId Property that represents Viewport ID for this Viewport object. Note that this property does not relate to CVPORT system variable.
Public property WorldToEyeTransform Property that represents transformation matrix from WCS to EyeSpace for this Viewport object.
