This GIMP (GNU) tutorial demonstrates how to Round An Image’s Corners: Add A Drop Shadow And A New Background. To work along, you are welcome to download the Start Image I am working with Here. Unzip the file and open the image onto GIMP’s workspace.
Launch GIMP & Organise Its Workspace & Palettes
This filter rounds the corners of an image, optionally adding a Drop Shadow and a Background Layer. The filter works on RGB and greyscale images that contain only one Layer. It creates a copy of the image or can optionally work on the original. It uses the current background colour to create a Background Layer.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu choose View then select a Zoom Tool from the subsequent drop-down list.
Open your choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Now, from the top menu, choose Filters then choose Decor and then choose Rounded Corners. And from the subsequent Script-Fu Rounded Corners dialogue box, enter settings of your choice, and then click OK.
Background Colour Tip
If you mark Add Background a Background that represents the Background Colour Swatch will be applied to your image. In this instance, a White Background will be applied to my Rounded Corners Image.
Drop Shadow Note
If you mark Add Drop-shadow, a Drop Shadow Layer will be added to your image.
For personal results, experiment with the Rounded Corners settings.
Change The Black Background: Tip
To remove the White Background: left-click to remove the Background Layer’s Visibility (Eye) Icon. This temporarily hides the Layer’s Contents - as illustrated below-right.
Fill Layer Tip
Now you have removed the White Background, you can create a Fill Layer, and Fill it with either a Solid Colour, Pattern or a Gradient - as demonstrated by my Create A Fill Layer PDF Tutorial (Layers).
To finish, from the top menu, choose Image and then choose Flatten Image.
Congratulations, your Rounded Corners Conversion is complete, and is ready to Optimise and Save.
