Adding Guidelines in GIMP

There are several methods to add guidelines in GIMP:

1. Dragging from Rulers

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].

Removing Guidelines in GIMP

There are several ways to remove guidelines:

1. Removing Individual Guides

1. Select the Move tool. 2. Hover over the guide until it turns red. 3. Click and drag the guide outside the image canvas5.

2. Removing All Guides

To remove all guides at once:

1. Go to Image > Guides > Remove All Guides8.

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.
