bitmap processing

--------------------------------
This menu is for the processing of bitmap images. Bitmap images have only one bit for each image pixel. You create them by performing an image segmentation (see the SEGMENT menus).

There are currently four options for bitmap processing:

  1. Path-to-target processing lets you analyze the spatial relationship between pixels of two kinds in an image. In particular, path-to-target processing calculates, on a pixel-by-pixel basis, the shortest path connecting pixels of one kind to the nearest pixel of another kind.
  2. Dilation-erosion processing lets you Dilate and Erode bitmaps. Dilation and Erosion make the objects in a bitmap larger and smaller, respectively.
  3. Bitmap Algebraic processing lets you perform boolean algebraic operations on bitmap images. Using these operations, for example, you can use one bitmap to chop out portions of another bitmap.
  4. Bitmap Punchout processing lets you use a bitmap as a template to punch out portions of an image. The effect is similar to placing a stencil over the image; only certain pixels of the punched-out image will be visible.
