Parameters

graphicContext

Graphic context on which to draw.

objectIndex

Index of the parent 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. of the hole to draw.

holeIndex

Index of the hole 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.

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.

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.
