#### 13.11.1. Overview

Afbeelding 17.309. Applying example for the Grid filter

Original image

Filter “Grid” applied

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 with the GIMP's foreground color. (Note: this plug-in was used to create demonstration images for many of the other plug-ins.)

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

#### 13.11.2. Activating the filter

This filter is found in the image window menu under Filters → Render → Pattern → Grid.

#### 13.11.3. Options

Afbeelding 17.310. “Grid” filter 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.

Besides, for some options, you can select the unit of measurement thanks to a drop-down list.

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. The Intersection parameter clears the space between the intersection point and the end of the arms of the intersection crosses.

Offset

  Sets the offset for grid lines with respect to the upper left corner. For intersections, sets the length of the arms of the intersection crosses.

Color Selectors

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