Transforming and Distorting Images
To use Displace:
1
Choose Filter > Distort > Displace.
2
To define the magnitude of the displacement,
enter a value between –999 and 999 in the
Horizontal and Vertical Scale text boxes.
When the horizontal and vertical scales are 100%,
the greatest displacement is 128 pixels (because
middle gray produces no displacement).
3
If the displacement map is not the same size as
the selection, select how the map will fit the image:
•
To resize the map, select Stretch to Fit.
•
To fill the selection by repeating the map in a
pattern, select Tile.
4
Select how to fill voids that are created by the
filter in the image:
•
To fill voids with content from the opposite edge
of the image, select Wrap Around.
•
To extend the colors of pixels along the image’s
edge in the direction specified, select Repeat
Edge Pixels.
5
Click OK.
6
Select and open the displacement map.
Photoshop Elements applies the map to the image.
Applying the Pinch filter
The Pinch filter squeezes a selection or layer
inward or outward.
To pinch a layer or selection:
1
Select the layer or area you want to pinch.
2
Choose Filter > Distort > Pinch.
3
Drag the slider to the right, into positive values,
to pinch a selection inward toward its center; or to
the left, into negative values, to shift a selection
outward.
4
Click OK.
Applying the Shear filter
The Shear filter distorts an image along a curve.
To shear a layer or selection:
1
Select the layer or area you want to shear.
2
Choose Filter > Distort > Shear
3
To define a distortion curve, do one of the
following in the Shear dialog box:
•
Click anywhere on either side of the vertical
line.
•
Click on the vertical line, and then drag the new
curve point.
You can drag any point along the curve to adjust
the distortion, and you can add additional curve
points.
4
Select one of the following in the Undefined
Areas options:
•
Wrap Around fills new voids in the image with
content from the opposite side of the image.
•
Repeat Edge Pixels extends the colors of pixels.
Banding may result if the edge pixels are
different colors.
You can click Defaults to start over and return the
curve to a straight line.
