gdkDrawTrapezoids

Description

Draws a set of anti-aliased trapezoids. The trapezoids are combined using saturation addition, then drawn over the background as a set. This is low level functionality used internally to implement rotated underlines and backgrouds when rendering a PangoLayout and is likely not useful for applications.

Usage

gdkDrawTrapezoids(drawable, gc, trapezoids)

Arguments

`drawable`	a `GdkDrawable`
`gc`	a `GdkGC`
`trapezoids`	a list of `GdkTrapezoid` structures
