EasyImage::Contour
Follows the contour of an 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
sourceImage
Pointer to the source image/ROI.
contourMode
Traversal mode, as defined by EContourMode.
startX
Start point abscissa.
startY
Start point ordinate.
thresholdMode
Thresholding mode as defined by EThresholdMode.
threshold
Threshold level.
connexity
Contour connexity, as defined by EConnexity.
path
Pointer to the destination vector.
freeman
Specifies if Freeman codes are to be retrieved rather than pixel values.
Remarks
A threshold is applied so that objects become blobs. The contour is a closed or not (see property Get/SetClosed)
connected path, forming the boundary of the blob Synonym of object..
When destination vector is an EBW8PathVector or a EBW16PathVector, this vector can contain two different information.
If the bFreeman argument is false, which is the default value, member m_bw8(16)Pixel in the vector
elements contains the gray-level value of the contour pixels. If it is true, the member instead gives the Freeman
code leading from a pixel to next. The Freeman codes are numbered from 0 in the horizontal direction and incremented
anticlockwise.
