GIMP Tutorial: Removing Text and Watermarks from Images

In this tutorial, we will explore how to use a GIMP plugin called Resynthesizer to remove text and watermarks from images. This tool is particularly effective for small areas and offers a quick solution for editing out unwanted elements. While it may not be perfect, it provides a strong foundation that can be refined using GIMP’s healing tools.

Installing Resynthesizer Plugin

Before we begin, make sure you have the Resynthesizer plugin installed. You can download it from various sources online, including its GitHub repository. Once downloaded, follow these steps to install it:

  1. Unpack the Zip File: Download the plugin, which usually comes as a zip file. Extract the files.
  2. Locate GIMP's Plugins Folder: Open GIMP and navigate to Edit > Preferences. Scroll down to the Folders section and find Plugins.
  3. Paste the Plugin Files: Open the plugins folder (preferably the one in Program Files for Windows users) and paste the extracted files into this directory.

Removing Text from an Image

  1. Open your Image in GIMP: Start by loading the image from which you want to remove text.
  2. Select the Text Area: Use the Color Select Tool to highlight the text. Click and drag to make sure you capture the text, then select Select > Grow and grow the selection by 2 pixels.
  3. Apply Resynthesizer: With the area selected, go to Tools > Image > Enhance > Heal Selection. Set the context sampling to about 50 pixels. If necessary, you can try a smaller value (e.g., 20 pixels) to see if it yields better results depending on the surrounding content.
  4. Fine-tuning: After the plugin processes the image, refine imperfections using GIMP's healing tool.

Example Workflow

  1. Use the Color Select Tool to select the text by dragging.
  2. Grow the selection by 2 pixels.
  3. Go to Tools > Image > Enhance > Heal Selection and set the context sampling to 50 pixels. Click OK.
  4. Review the edited area and use the healing tool to fine-tune any rough patches.

Here is a visual representation of the before-and-after of the image:

  • Before: The image includes unwanted text.
  • After: The text has been removed with small irregularities that can be further refined.

Conclusion

This method is a quick and efficient way to remove small unwanted elements from images. While it works best for small areas, larger or more complex textures may require additional touch-up work. The Resynthesizer plugin combined with GIMP’s healing tools makes for a powerful and versatile editing process.
