NOTE: All but the last three gage operations apply to the line, arc, and
circle gages. The last three apply only to arc and circle gages.

White Pixels; Black Pixels

These two gage operations are available only when you select the binary
gaging mode
. The pixel counting operations count the total number of white
or black pixels along the full length of the gage. Figure 7.5 (A) (page 7–8)
shows a linear gage performing a black pixel counting operation across a
workpiece, while (B) shows the same gage performing a white pixel counting
operation across the same workpiece.

Note that black pixel count (190 pixels in the A example) is the total of the
pixels in all of the black rectangles, while the white pixel count (117 in the B
example) is the total of the pixels in all of the white spaces between the black
rectangles, plus the white area on each end of the gage.
