Despeckle - Detects the edges in a picture and blurs all of the picture except ●
those edges. It removes noise while preserving detail, and can be useful for
removing dust from a scanned image.
Gaussian Blur - Smooths transitions by averaging pixels next to hard edges ●
of defined lines and shaded areas in a picture. By checking Blur Picture
and/or Blur Mask, you can apply this filter separately to pictures and their
alpha masks.
Unsharp Mask - Compares pixel values in a defined area to the specified ●
threshold value. If a pixel has a lower contrast value than the threshold value,
its contrast is increased.
Find Edges - Outlines the edges of a picture with dark lines against a white ●
background.
Solarize - Blends negative and positive areas of a picture, producing a ●
photographic solarization effect. To use the Solarize dialog box, enter a
Threshold value in the field or drag the slider. The value specifies which
pixels to modify - those with values lower than the threshold are considered
negative and those with values higher than the threshold are considered
positive. The pixel values are then inverted.
Diffuse - Shuffles pixels so the picture looks less focused. ●
Emboss - Makes areas of the picture appear raised or stamped. ●
Embossing Effects - When the Emboss filter is applied, you can specify the ●
direction from which to raise or stamp the picture using the Embossing
Effects filter. Click the directional arrows in the Embossing Effects dialog box
to apply different directions. For example, clicking the upper-right arrow
might specify that when you pushed a stamp onto an object, you pushed
slightly to the right, smearing the stamp in that direction.
