 Add Grid

This tool is used to overlay a black or white grid over the current image.  You can move the origin of the grid by clicking on the image with the mouse.

This function is used when you need to subdivide the image into separate regions to be measured separately.  It can also be used in order to provide a reference for orienting an image.  Whenever a single pixel wide line separates two objects, the 4-way boundary rule must be used to measure them (located on the Data Options page of the Northern Eclipse Options Dialog).

The X and Y scrollbars set the grid size.  You can show only vertical or only horizontal lines by deselecting the X and Y checkboxes.  The “Bright on Dark” setting allows you to choose between a white and black grid. 

The grid remains as an overlay on the image even if you select another tool.  Once you are done with the grid overlay, you can remove it using the Remove Last Selection or Remove All Selection functions.  You can stamp the grid into the image by selecting the “Stamp” button.  The grid will then become part of the image and the overlay is removed.  Alternately, you can use the Duplicate Display function to stamp all overlays into the image.
