GradientShape

Remarks

⚠ A discriminator rather than three axis conventions, because radial has no axis. The two-stop implementation used a zero GradientAxis as its "no gradient" sentinel, which works exactly as long as every gradient has a direction. A radial one does not — its parameter is a distance from the centre — so a radial fill would have had to write a meaningless non-zero axis to avoid being erased, and the first person to read that axis would have believed it.

The numbers are the shader's: they are written into UiShape.Size.w, whose previous life was a zero-or-one gradient flag. None is that flag's zero and Linear is its one, on purpose, so growing the record moved no picture.

Fields and properties (4)

• None

  No gradient. The box is filled with its own colour.

• Linear

  CSS's linear-gradient(): the ramp runs along an axis.

• Radial

  CSS's radial-gradient(): an ellipse from the centre out.

• Conic

  CSS's conic-gradient(): the ramp sweeps around the centre.
