Reduce the edge width. The numeric fields take values representing the
pixel width of the blur filter along the X-axis and the Y-axis (from 0.000
to 30.000 float).
Blur
Link: Blurs the width and height proportionally. Default is on.
Gaussian: Default is on, but can be changed to a box blur filter.
Extract Alpha
The Extract Alpha tool lets you extract the alpha channel from its primary
input and has no control parameters. This tool always outputs an alpha-only
image, implying that if the input is an RGB-only image, the output will be a
constant 1.0 alpha image.
NOTE The Extract tool will extract a selected channel into an alpha-only image.
The Extract Alpha tool is just a more convenient and readable tool to use when
the selected channel is always the input alpha channel.
Fade Tool
The Fade tool provides a convenient way to modify the transparency of an
image. The usual case will be to fade an image without having to do it at the
same time as compositing. This tool fades an image by reducing the value of
its alpha channel, making it transparent.
The Opacity parameter controls the fading effect; at 100% (the default value)
the image is unchanged; smaller values fade more; at 0% the image is
completely transparent.
This tool in an image modifier; it restricts processing to the masked region
and propagates it to the output. The Fade tool can be muted, as well as
animated and masked; it affects the alpha channel only.
