Parameters
graphicContext
Graphic context on which to draw.
feature
The feature of interest.
objectIndex
Index of the object to draw.
zoomX
Horizontal zooming factor. By default, no scaling is used.
zoomY
Vertical zooming factor. If set to
panX
Horizontal panning value expressed in pixels. By default, no panning occurs.
panY
Vertical panning value expressed in pixels. By default, no panning occurs.
drawDiagonals
Specifies whether or not the diagonals of the ellipses and of the rectangles are to be drawn.
layerIndex
The index of the layer of interest. If this parameter is left unspecified, the default layer will be taken into consideration.
Remarks
Drawing is done in the device context associated to the desired window. The current pen is used.
This methods throws an exception if no layer index is specified and if, simultaneously, the coded image contains several layers. Indeed, in such a case, no default layer exists.
Trying to draw the features EDrawableFeature_FeretBox and EDrawableFeature_WeightedGravityCenter will result in an exception, as they only make sense for EObjectSelection.
Deprecation notice: All methods taking HDC as parameter are deprecated. It is recommended to use their alternative taking a EDrawAdapter by using a instance of EWindowsDrawAdapter.ECodedImage2.DrawObjectFeatureWithCurrentPen
