– Draw Ellipse: Click and drag to place an elliptical patch of any size from one corner to
the opposite corner. Once drawn, you can click on any edge of the overlay and drag
to reposition it.
– Place Patch: Lets you place small patches specifically for tiny details such as dead
pixels. When you choose this option, a 'new patch size' slider appears that lets you
adjust the size of the patches you're about to place prior to placing them. Once
drawn, you can click on the edge of any patch and drag to reposition it.

Show Patches:
This checkbox lets you show or hide the onscreen outline of every
patch in the viewer.
Hide During Interaction:
you're moving a patch; this makes it easier to see the effect of moving the patch on the
image, without the outline getting in the way.
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.
