Gradient Flare effect reminds the effect you get when you take a photograph of a blinding light source, with a halo and radiations around the source. The Gradient Flare image has three components: Glow which is the big central fireball, Rays and Second Flares
The Settings tab allows you to set manually the parameters while the Selector tab let you choose presets in a list.
When Auto update preview is checked, parameter setting results are interactively displayed in preview without modifying the image until you click on OK button.
You can set X and Y (pixels) coordinates of glint using the input box or by clicking into the preview. The coordinate origin is at the upper left corner.
The radius of the effect. The slider limits the range of possible values, but using the input box you can enter greater values.
Turn the effect.
Change the tint (color) of the effect.
Turn the Second flares.
Vary the distance applied for the Second flares.
Settings of the anti-aliasing following parameters like Depth and Threshold. (See also Supersampling .)
The Selector tab allows you to select a Gradient Flare pattern, to change it and save it.
When you click on this button, you create a new Gradient Flare pattern. Give it a name of your choice.
This button brings up the Gradient Flare Editor (see below).
This button allows you to duplicate selected Gradient Flare pattern. You can edit the copy without altering the original.
This button deletes the selected Gradient Flare pattern.
The Gradient Flare Editor is also organized in tabs:
Slider and input box allows you to reduce glow opacity (0-100).
You can choose between four modes:
In this mode, the glow covers the image without taking into account what is beneath.
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.
Light/Dark areas of glow enhance corresponding light/dark areas of image.
Dark areas of image are enlightened by corresponding light areas of glow. Imagine two slides projected onto the same screen.
Options are the same as for Glow Paint Options.

By clicking on the rectangular buttons, you can develop a long list of gradients. “%” gradients belong to the Editor.
The selected gradient is drawn radially, from center to edge.
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).
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%.
Sets size of glow in percent (0-200).
Sets the origin of the angular gradient (-180 +180).
Sets glow color, according to the HSV color circle (-180 +180). (Cf. The triangle color selector.)
The options are the same as for Glow.
Options are the same as in Glow.
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.
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.
When you click on this button, you produce a random seed that will be used by the random generator. It is each time different.
