A colon-separated list of weighted color values: WC(:WC)* where each
WC has the form C(;F)? with C a
color value and the optional
F a floating-point number, 0 ≤ F ≤ 1. The sum of the floating-point
numbers in a
colorList must sum to at most 1.
NOTE: Gradient fills, described below, are currently only available via *CAIRO or SVG rendering.
If the colorList value specifies multiple colors, with no weights, and a
filled style is specified, a linear gradient fill is done using the first two
colors. If weights are present, a degenerate linear gradient fill is done.
This essentially does a fill using two colors, with the weights specifying
how much of region is filled with each color. If the
attribute contains the value radial, then a radial gradient fill is done.
These fills work with any shape.
See Gallery/gradient for real-world examples of using gradients.
