Image Filter Tools - Point
The Point Image Filter Tool filters a region of the image with a pixel-by-pixel "global" image-enhancement technique, like thresholding, inverting, equalization, clipping or stretching; outputs a Tool Image that can be referenced by other Location or Inspection Tools.
The "global" image-enhancement Operations involve assigning a greyscale value to the output pixel based on the individual greyscale values of the pixels in the tool's region.
The Point Image Filter Tool is useful in situations where you need to enhance an area of the image to better detect a feature for an inspection, such as clipping the hotspots from a surface to better read OCR characters, or stretching the features of a part to gain enhanced contrast, for example.
