Resizing a layer in GIMP is commonly done using the Scale Tool. This tool allows you to change the dimensions of a selected layer, keeping its content intact but adjusting its size.
Using the Scale Tool from the Toolbar
The primary method to resize a layer involves selecting the layer you want to modify and then activating the Scale tool.
As shown in tutorials like ["How To Resize Layers & Your Canvas in GIMP"](), the process often starts via the toolbar. Once you select the Scale tool from the toolbar, you can then click directly on your image. This action will activate the scale tool specifically for the layer you currently have selected in the Layers panel.
Here's a simple breakdown of the steps:
- Select the Layer: In the Layers panel (usually located on the right side of your GIMP window), click on the name or thumbnail of the layer you wish to resize. Ensure this layer is highlighted, indicating it is active.
- Activate the Scale Tool: Go to the GIMP Toolbox (typically on the left). Find and click on the Scale Tool icon. It often looks like four small boxes forming a larger square with arrows pointing outwards.
- Click on the Image: With the Scale tool selected, move your mouse over the image window and click on the layer you want to resize.
- Adjust Size: A dialog box and handles will appear around the layer. You can now:
- Click and drag the handles on the corners or sides of the layer boundary to visually resize it. Holding down the Ctrl key while dragging a corner handle will maintain the aspect ratio (prevent stretching).
- Enter precise width and height values into the dialog box. Click the chain icon between the width and height fields to link/unlink them, controlling whether the aspect ratio is locked.
- Confirm the Resize: Once you are satisfied with the new size, click the Scale button in the dialog box to apply the changes to the layer.
This method directly applies the scaling transformation to the content of the selected layer, making it larger or smaller within the overall image canvas.
