ECodedImage2::DrawObjectFeature

Draw a given feature Geometrical property of a coded element. of the designated object In a general content, the term object should be understood with the meaning of a class instance. In EasyObject, an object is a maximally-sized area of adjacent connected pixels belonging to the layer foreground..

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 0, the default value, the horizontal zooming factor is used instead, so as to provide isotropic zooming.

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 A binary image constructed by a segmentation process. of interest. If this parameter is left unspecified, the default layer will be taken into consideration.

color

The color in which to draw the overlay.

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.
