Unleashing the Power of GIMP and BIMP for Image Editing: Resizing the Canvas in Batch

Like many budding designers, I’ve found a powerful ally in GIMP. This free image editing software stands toe-to-toe with Adobe Photoshop, offering a cost-effective solution for all your design needs.

GIMP: A Designer’s Best Friend

GIMP, or GNU Image Manipulation Program, is a versatile tool that caters to a wide range of tasks. Whether you’re looking to retouch photos, compose images, or even batch process, GIMP has got you covered. It’s customizable, allowing you to tailor the interface to your liking, and supports a variety of file formats. With features like photo enhancement, digital retouching, and hardware support, GIMP is a comprehensive package that can handle everything from simple paint tasks to complex image manipulation procedures.

BIMP: Batch Processing Made Easy

When it comes to batch processing, GIMP’s functionality can be extended with an excellent add-on called BIMP. Developed by Alessandro Francesconi, BIMP allows you to apply a set of manipulations to an entire group of images. It offers a user-friendly interface and a host of batch functions, including resizing, cropping, flipping, rotating, blurring, sharpening, color correction, watermarking, renaming, and changing compression and format.

Installing BIMP

BIMP can be easily installed on your system. After installation, you’ll find the “Batch Image Manipulation…” option inside the “File” menu of GIMP.

Overcoming BIMP’s Limitations

While BIMP is a powerful tool, it does have its limitations. One such limitation is the absence of a batch command for resizing the canvas. This operation is crucial when you want to enlarge the overall image size while keeping the existing design at its original size. Although this operation can be performed in standard GIMP via the “Canvas Size…” option in the “Image” menu, BIMP does not offer this feature.

Resizing the Canvas Across All Your Images

Here’s a step-by-step guide to resize the canvas across all your images:

  1. Select “Batch Image Manipulation” from the File menu of GIMP.
  2. Set your input and output folders.
  3. Add a new manipulation of the type “Other GIMP Procedure” => “script-fu-drop-shadow”.
  4. In the dialog box, set the x and y coordinates for the right and bottom increase in canvas size you want.
  5. Select the color you want the shadow to be.
  6. Select the “Allow resizing” option.
  7. Apply the manipulation across all your files.
  8. Now repeat this manipulation, but with negative coordinates for the drop shadow and apply it.

And voila! You’ve successfully resized the canvas across all your images!

With GIMP and BIMP at your disposal, the world of image editing is your oyster. Happy designing!
