Coy a part of photo into another photo

[Carel]

1. Open the image that you want to copy pixels from and use the Layers panel to select the pixel layer that you wish to copy from.
2. Click the Patch Tool.
3. On the context toolbar, select Selection is source.
4. Drag on the image to define a selection. This will be the global source area.
5. On the context toolbar, click Set Global Source.
6. Open the image that you want to paint the sample into.
7. Use the Layers panel to either select an existing pixel layer to copy to, or to create a new pixel layer.
8. Click the Patch Tool.
9. On the context toolbar:
   • Ensure Selection is source is still selected.
   • Select Global from the layer selection dropdown.
10. Click on the image to place pixels from the source area.
11. (Optional) Drag the nodes of the applied area to modify the scale and rotation. Alternatively, use the Scale and Rotation controls on the context toolbar, or use the up and down arrow keys to control scale and the left and right arrow keys to control rotation.
