Figure 15.120: ‘Gﬂare Editor’ options (Glow)

Gradients By clicking on the rectangular buttons, you can develop a long list of gradients. "%" gradients belong to the

Editor.

• Radial gradient: The selected gradient is drawn radially, from center to edge.

• Angular gradient: The selected gradient develops around center, counter-clockwise, starting from three o’clock if

"Rotation" parameter is set to 0. Radial and angular gradients are combined according to the Multiply mode: light

areas are enhanced and colors are mixed according to CMYK color system (that of your printer).

• Angular size gradient: This is a gradient of radius size which develops angularly. Radius is controlled according

to gradient Luminosity: if luminosity is zero (black), the radius is 0%. If luminosity is 100% (white), the radius is

also 100%.

Parameters

• Size (%): Sets size (%) of glow (0-200).

• Rotation: Sets the origin of the angular gradient (-180 +180).

• Hue rotation: Sets glow color, according to the HSV color circle (-180 +180).
