Syntax
RemarksThis is a pixel-based measurement. Is is the length of boundary
pixels for the blob of pixels under or interior to the region boundary.
Diagonal pixel transitions are given a distance of the diagonal size of one
pixel (e.g., square root of 2 if no spatial calibration is in effect).
Horizontal or vertical runs of boundary pixels contribute one-less than the
number of pixels in the run (e.g., the mRgnPerimeter2 value of an 8 by 8
block of pixels is 28, or 7 from each side). As a measure of region
perimeter it is generally less accurate than the mRgnPerimeter measurement,
which is the length of the boundary polygon.
