Main Functions

Use standard edge blending controls to set the precise width, shape and midpoint you
need to blend overlapping edges together smoothly.
determines how much area is used for blending along an
Blend Width
overlapping edge. Slidebar values represent the number of 8-pixel steps used
for the blend. For example, a setting of "3" creates a blended edge 24 pixels
wide. A setting of "0" signifies no blending. For best results in most
applications, use a blend width of 16-48 steps (128-384 pixels).
Ranges: 0-80 horizontal, 0-60 vertical.
determines the rate of
Blend Shape
roll-off across the blend width, i.e.
how quickly the white levels
across the blend change from light
and dark. Increasing the Blend
Shape setting accelerates the rate
of change at both extremes so that
less of the region appears mid-
gray (see Figure 3. 32).
Decreasing the Blend Shape
setting slows the rate of change so
that more of the region appears
mid-gray. For most applications, this subtle control is best left close to 50.
determines the white
Blend Midpoint
level at the blend midpoint (the point
equidistant between the beginning
and end of the blend). Increasing the
Blend Midpoint setting creates a
blend that appears brighter than the
rest of the image. Decreasing the
Blend Midpoint setting creates a
blend that is darker than the rest of
the image. A setting of 50 means the
midpoint is approximately 50%
black—for best results in most
applications, keep fairly close to this default.
