Display preferences: Grid
The grid is a rectangular overlay that may be useful for:
- Checking the calibration of lenses.
- Dividing a region into fixed areas for further analysis.
The grid is anchored at the reference point and moves along with the tracing as the tracing and stage are moved.
Grid enabled
Displays a rectangular grid; its size is defined by Grid Spacing.
Bright grid
Displays grid at maximum brightness. Use when the slide illumination levels are high. The default is medium brightness.
Show grid labels for each cell
Displays the coordinates of the grid.
- A0 is the coordinate of the reference point.
- Letters go in alphabetical order to the right of the reference point, and numbers increase below the reference point.
- Grid intersections to the left of the reference point are listed with negative letters.
- Intersections above the reference point are listed with negative numbers.
Grid spacing
Sets the dimensions of the grid.
- When you change the objective from one magnification to another, the grid changes size accordingly.
- At low magnifications, the grid can become so dense that the entire screen is covered with nothing but grid lines. The program prevents this by automatically turning off the grid when the spacing between grid lines drops below 4 pixels.
