Magnifies an elliptical region of the source to
create a glass lens refraction effect.
Inputs:
Source: The input clip to be warped.
Parameters:
Magnify Amount: Default: 2, Range: any.
Amount to scale the image within the magnified
region. Use values below 1.0 to shrink the image instead within the
lens.
Magnify Rel: X & Y, Default: [1 1], Range: 0 or greater.
The relative horizontal and vertical magnification.
Center: X & Y, Default: [0 0], Range: any.
The center of the lens shape. This parameter can be adjusted using the Center Widget.
Lens Radius: Default: 0.6, Range: 0 or greater.
Radius of the inner part of the lens. Within
this region, the source is scaled by the full magnify amount. This parameter can be adjusted using the Lens Radius Widget.
Lens Edge Width: Default: 0.5, Range: 0 or greater.
The width of the lens edge, as a fraction of the
inner radius. In the edge area of the lens, magnification tapers off
from the full magnify amount to no magnification. This parameter can be adjusted using the Lens Radius Widget.
Lens Rel Height: Default: 1, Range: 0.1 or greater.
The relative vertical size of the lens. Increase for
a taller ellipse, decrease for a wider one.
Lens Rel Width: Default: 1, Range: 0.1 or greater.
The relative horizontal size of the lens. Increase for
a wider ellipse, decrease for a taller one.
Lens Rotate: Default: 0, Range: any.
Rotation in degrees of the lens. Note that rotation
will have no effect when Rel Width and Rel Height are equal and the
shape is a perfect circle. This parameter can be adjusted using the Lens Rotate Widget.
Lens Edge Shape: Default: 0.5, Range: any.
Determines the curve of the magnification amount
within the edge of the lens. If set to zero, magnification tapers
off linearly. If set to one, magnification tapers off in a smoother
curve, which can reduce the visual perception of the border of the
lens. Other values interpolate between the two.
Filter: Check-box, Default: on.
If enabled, the image is adaptively filtered when it is
resampled. This gives a better quality result when parts of the image
are warped smaller.
Wrap: X & Y, Popup menu, Default: [REFLECT REFLECT].
Determines the method for accessing outside the borders of the
source image.
NO: gives black beyond the borders.
TILE: repeats a copy of the image.
REFLECT: repeats a mirrored copy. Edges are often less
visible with this method.
