Centroid Method
Syntax
CWIMAQVision.Centroid SourceImage, xCentroid, yCentroid [, MaskImage]
Return Type
On success, this method returns 0. On failure, this method returns a negative number.
Purpose
Obsolete—Use Centroid2 instead. Computes the centroid of an image.
Remarks
Use this method with image types U8, I16, and SGL. MaskImage must be a U8 image.
Parameters
SourceImage As CWIMAQImage
The image whose centroid the method calculates.
xCentroid As Single
On return, the x-coordinate of the centroid.
yCentroid As Single
On return, the y-coordinate of the centroid.
MaskImage As Variant
[Optional] A CWIMAQImage object that specifies the region in the image to use for computing the centroid. The method uses only those source image pixels whose corresponding mask pixels are non-zero to compute the centroid. Do not set this parameter if you want the method to use the whole image in the centroid calculation.
