To transform a selection in GIMP, you need to utilize the transform tool in the toolbox. This allows you to alter the shape and position of the selection. Here's how:
Steps to Transform a Selection
-
Select the Transform Tool: Locate and select the transform tool from the GIMP toolbox. This tool is usually represented by an icon showing an arrow with a square shape.
-
Choose the Target: Within the tool's Tool Options dialog, you will find a “Transform:” option. Here, you need to specify what you want to transform. This could be:
- Layer: The entire layer that the selection resides on.
- Selection: The actual selection itself.
- Path: If you've created a path that represents a selection, this option will transform that path.
- Note: Transforming a selection directly modifies only the bounding box of the selection. Transforming a layer transforms the layer content. When transforming a path, you can reshape the path without changing the underlying image content.
-
Adjust Transformation Parameters: After selecting the target type for transformation, you can customize various transformation parameters:
- Scale: Change the size of the selection.
- Rotate: Turn the selection around its center point.
- Shear: Distort the selection by skewing its sides.
- Perspective: Change the perspective of the selection, making it appear as if it's tilted in 3D space.
- Flip: Flip the selection horizontally or vertically.
-
Execute the Transformation: After adjusting the parameters, you can apply the transform by clicking within the selection area or use the appropriate tool option for confirmation.
Practical Insights and Examples
- Transforming a Selection: When selecting the "Selection" option in the Transform tool's settings, and after clicking the selection on the image, it allows you to change the selection's shape and size within the existing canvas without altering the content of the image itself.
- Transforming a Layer: If you have a layer with some content, you can select “Layer” in the Transform tool and apply scaling, rotation, or shearing on the content of the layer.
- Transforming a Path: By working with paths and selections, you can perform complex edits. The Transform tool allows you to alter paths directly, thus enabling precise and flexible modifications.
Summary
By using the Transform tool and carefully choosing the “Transform:” option, you can gain a flexible way to change selections, layers, and paths in GIMP.
