Poloměr

The radius of the effect. The slider limits the range of possible values, but using the input box you can enter greater values.

Rotace

Turn the effect.

Hue rotation

Change the tint (color) of the effect.

Vector angle

Turn the Second flares.

Vector length

Vary the distance applied for the Second flares.

Adaptivní převzorkování

Settings of the anti-aliasing following parameters like Depth and Threshold. (See also Supersampling .)

6.4.4.1. Všeobecné

Volby vykreslení záře
Krytí

Slider and input box allows you to reduce glow opacity (0-100).

Paint mode

You can choose between four modes:

Normální

In this mode, the glow covers the image without taking into account what is beneath.

Součet

Pixel RGB values of glow are added to RGB values of the corresponding pixels in the image. Colors get lighter and white areas may appear.

Překrytí

Light/Dark areas of glow enhance corresponding light/dark areas of image.

Obrazovka

Dark areas of image are enlightened by corresponding light areas of glow. Imagine two slides projected onto the same screen.

Volby kreslení paprsků

Options are the same as for Glow Paint Options.

Volby kreslení druhé záře

Options are the same as for Glow Paint Options.

Přechody

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 the 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%.

Parametry
Size (%)

Sets size of glow in percent (0-200).

Rotace

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

Hue rotation

Sets glow color, according to the HSV color circle (-180 +180). (Cf. The triangle color selector.)

6.4.4.3. Paprsky

Přechody

The options are the same as for Glow.

Parametry

The first three options are the same as in Glow. Two are new:

# of Spikes

This option determines the number of spikes (1-300) but also their texture.

Spike thickness

When spikes get wider (1-100), they look like flower petals.

Přechody

The options are the same as for Glow.

Parametry

Options are the same as in Glow.

Tvar druhé záře

Second flares, these satellites of the main flare, may have two shapes: Circle and Polygon. You can set the Number polygon sides. The option accepts 1 side (!), not 2.

Hnízdo náhodných čísel

The random generator will use this value as a seed to generate random numbers. You can use the same value to repeat the same random sequence several times.

Randomize

When you click on this button, you produce a random seed that will be used by the random generator. It is each time different.
