General
Glow Paint Options
  • Opacity: Slider and input box allows you to reduce glow opacity (0-100).

  • Paint Mode: You can choose between four modes:

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

    • Addition: 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.

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

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

Rays Paint Options

Options are the same as for "Glow".

Second Flare Paint Options

Options are the same as for "Glow".

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).

Rays
Gradients

The options are the same as for Glow.

Parameters

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

Second Flares
Gradients

The options are the same as for Glow.

Parameters

Options are the same as in Glow.

Shape of Second Flares

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.

Random seed and Randomize
  • Random Seed: 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.
