There are several methods to add guidelines in GIMP:

The simplest way to add guidelines is by dragging them from the rulers:

1. Ensure rulers are visible (View > Show Rulers).
2. Click and drag from the top ruler to create a horizontal guide.
3. Click and drag from the left ruler to create a vertical guide[1].

=== 2. Using the Image Menu ===

For more precise placement:

1. Go to Image > Guides > New Guide (by Percent)[1].
2. Choose the direction (Horizontal or Vertical).
3. Set the position as a percentage of the image dimensions.
4. Click OK to create the guide[1].

=== 3. New Guide by Pixels ===

For pixel-specific placement:

1. Go to Image > Guides > New Guide.
2. Select the direction.
3. Enter the exact pixel position.
4. Click OK[19].

=== 4. Creating Multiple Guides ===

To add multiple guides at once:

1. Use the "Multiple Guides" plug-in from the GAT tools set.
2. Access it via Tools > Gimp-Atelier > Multiple Guides[10].

=== 5. Creating Guides from Selection ===

To create guides based on a selection:

1. Make a selection using any selection tool.
2. Go to Image > Guides > New Guide from Selection[15].

=== 6. Creating Center Guides ===

For center alignment:

1. Go to Image > Guides > New Guide (by Percent).
2. Set the position to 50% for both horizontal and vertical guides[4].

=== 2. Removing All Guides ===

To remove all guides at once:

=== 3. Hiding Guides Temporarily ===

If you want to hide guides without deleting them:

1. Go to View > Show Guides to toggle guide visibility[16].

== Tips for Working with Guides ==

- Enable "Snap to Guides" (View > Snap to Guides) to make objects align precisely with guides[13].
- Use the Move tool to reposition existing guides[7].
- Guides can be used with the Guillotine plugin to slice an image into sub-images[16].
- For angled or custom shape guides, you can use paths as a workaround[7].

== Advanced Guide Techniques ==

- Create equally spaced guides using third-party scripts like "New Guides Every X Pixels" or "Spaced H-Guides and Spaced V-Guides"[10].
- Use the "Grid (of Guides)" script to create a grid of guides with a specified number of cells[10].
- Experiment with the Layer Masks tool for more complex guide-like effects, especially useful for images with fine details[11].

By mastering these techniques for adding and removing guidelines in GIMP, you can significantly improve your precision in image editing and design tasks.
