This tool
creates gradients covering the entire layer; such gradients are usually used as
backgrounds. The exact pattern used depends on the chosen sub-option. The
pattern may be orientated towards any direction.
Simple Gradient
Linear-RGB Gradient
Rainbow Gradient
Customized Gradient
This tool can be used together with a gradient object to customize the fill pattern. For more on this, read the text on objects and the gradient object in particular. You may also switch the mapping mode to Linear RGB to do linear gradients.
Options
Color Gradient
This option creates a gradient between two colors.
Rainbow Gradient
This option creates a gradient across the hue plane.
Transparency Gradient
This option creates a gradient between two levels of transparency.
Custom Gradient
This option creates a gradient using the active gradient-map object. Gradient objects can be used to customize the progression of colors in a fill, both in terms of chromaticity and translucency.
