### 12.7. Grid

#### Overview

This filter is found in Image>Filters/Render/Pattern/Grid

It renders a Cartesian grid in the active layer, on top of the existing contents. The width, spacing, offsets, and colors of the grid lines can all be set by the user. By default, the lines are colored dark blue. (Note: this plugin was used to create demonstration images for many of the other plugins.)

| Tip
If you set the grid line widths to 0, then only the intersections will be drawn, as plus-marks.

#### Options

There are separate options for controlling the horizontal grid lines, vertical grid lines, and intersections. By default, the horizontal and vertical settings are locked together, so that all changes are applied symmetrically. If you want to change just one of them, click on the "chain" symbol below it to unlock them. The results of changing the "intersection" parameters are rather complex.

Width

  Sets the widths of the horizontal or vertical grid lines, or of the symbols drawn at their intersections.

Spacing

  Sets the distance between grid lines. For intersections, sets the distance from the intersection point for the starting points of the line segments that are drawn.

Offset

  Sets the offset for grid lines with respect to the upper left corner. For intersections, sets the distance from the intersection point for the ending points of the line segments that are drawn.

Color Selectors

  These allow you to set the colors of the grid lines and intersection marks.
