Luminosity uses the grayscale equivalent of the color to control the luminosity (or
Value) of underlying objects. Note that Luminosity has no effect on gray, white or
black underlying objects. The color of the object with Luminosity applied:
• Gray & White - increase the luminosity of underlying objects. White has the
greatest effect, producing saturated color.
• Black - remains as a black object.
• Other colors - convert the color to the equivalent shade of gray. (Yellow gives
light gray, Red dark gray.) Then increase the luminosity of underlying objects.
Hue
Hue is useful for color-shifting underlying objects. Its action is most easily understood
using the HSV color model. The color of the object with Hue applied:
• Gray, White, & Black - has no effect. These colors lie at the center of the color
wheel and so have no hue.
• If the underlying color is gray, white, or black - Hue transparency type has no
effect.
• Other colors - replace the Hue of the underlying color with the Hue of this object.
Use the Saturation and Value of the underlying color.
For more information on HSV refer to Color handling (on page 159).
For all these, the slider controls the amount of transparency from opaque (0%
transparent) to fully (100%) transparent.
Applying a flat transparency to an object also applies transparency to the line around
the object. It is not possible to set different transparencies, but you can remove the
line by setting it to no color or by selecting "None" as the outline width. To create an
object with a transparent fill and a non-transparent line, use a non-flat transparency
type.
For more information on colors see Color Handling (on page 159).
Enhance
See Enhance below for more information on Enhance transparency.
Enhance
Enhance transparency allows you to modify any part of your design using the Enhance
Photo Tool, just as if it was a photo. For example you can draw a shape over any part
of your design, apply enhance transparency to it and then adjust the brightness of just
the area of your design which is covered by the shape.
