Patch Type
There are three methods you can use to attempt to fix the contents of a selected patch. When
drawing new patches, the currently selected patch type will determine what the next patch
will be. When you've selected an existing patch, changing the patch type will change how that
patch works.
Spatial
Automatically fills the interior of the selected patch with pixels drawn from the surroundings of
the patch, using the fill method. This works well for small blemishes, but for large blemishes a
pattern might be discernible, which gives away the effect.
Clone
Clone mode copies part of the image to fill a shape or patch placed over the thing you want to
remove. In this mode, clicking and dragging to place a rect or ellipse over an imperfection is
followed by a second click to place the sample region you want to clone. Clicking once to place
a patch will be followed by a second click to place the sample region. Selecting an existing
shape or patch and choosing Clone lets you click on the shape to position the clone region.
The sample region is indicated by a dotted shape that's connected to the original shape.
Blend Clone
Operates similarly to clone mode, except the copied part of the image that fills the rect, ellipse,
or patch is blended with the image to integrate it more softly.
Fill Method
When using the 'spatial patch type', the fill method determines how the blemish in the image
is repaired.
Grid
Samples the pixels surrounding the rect, ellipse, or patch, and blurs them inward both
horizontally and vertically. Extremely effective for tiny blemishes. For larger blemishes, a
grid-like pattern may emerge.
Horizontal
Samples the pixels to the left and right of the rect, ellipse, or patch, and blurs them inward.
Vertical
Samples the pixels to the top and bottom of the rect, ellipse, or patch, and blurs
them inward.
Patchy
Samples pixels from all around the rect, ellipse, or patch, and expands and blurs them
together to create a soft, non-uniform region with which to repair the blemish. Doesn't have
the patterning of the grid methods of fill, but produces an extremely smooth result.
Smooth
Simply uses a gaussian blur to repair the blemish.
