Patching

Patching is a retouching technique which involves replacing an undesirable pixel region with a patch (a drawn freehand selection area) made up of pixels sourced from another, more suitable, part of your image or another document.

About patching

Patching, like healing, blends the target pixels with the sample pixels by matching the texture, tone, and transparency of the sample pixels with the target pixels. For effective results, colours in the source and target areas should vary slowly to help create a seamless boundary that blends into the target's surroundings.

Take care to avoid including in your source sharp edges where colour changes dramatically, which can introduce unwanted colour tinges at the target.

When patching, the context toolbar offers options to apply only the texture of the source to the target, and to apply a level of transparency so the target and source pixels are blended together.

Selection

The selection can act as any of the following:

Patch To patch when selection is target:
  1. Use the Layers Studio to either select an existing pixel layer to copy to, or to create a new pixel layer.
  2. From the Photo Persona, select the Patch Tool.
  3. Drag on the image to draw a freehand selection area. This will be the target area.
  4. Adjust the context toolbar settings. Repeat the above step if necessary.
  5. Drag (starting within the selection) to define the source area.
  6. (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.
  7. Tap anywhere on the image to confirm placement and remove the selection.
