field,
enter an amount of variation from the selected color, or enter 0 for an exact
color match.
Color Variation -This is the percentage of the hue that software will use to
scan
for variations of the background pixels along the color spectrum. The soft-
ware
removes pixels by sampling the first one located in the upper left-hand corner
of
the image. It then uses this setting to scan for pixels of a similar hue along the
specified percentage of the color spectrum. A higher value means that soft-
ware
will scan and remove pixels across a wider percentage of the color spectrum.
A
lower setting means that software will confine the removal to pixels that more
closely match the first one that was sampled.
For example: If you enter a setting of “30” here, and if the image's first pixel is
a
shade of green, the software will scan and remove all shades of green across
30
percent of the spectrum (and possibly into portions of the yellow and blue
color
ranges).
Intensity Threshold -This is the percentage that the software will use to
scan for
variations in color intensity. The software removes pixels by sampling the first
one located in the upper left-hand corner of the image. It then uses this set-
ting as
a threshold by which all pixels of a certain intensity (and higher) will be
scanned.
A higher value means that the software will confine its removal to the brighter
pixels that fall within the specified Hue Variation range. A lower setting
means
that the software will widen its scan and remove a broader range of bright
and
dark pixels within the specified Hue Variation.
For example, if you enter a setting of “60” here and a setting of “30” in the
Hue
Variation box, and if the image’s first pixel is a shade of green, then the
