RGtk2 (version 2.20.21)

cairoPatternCreateRadial: cairoPatternCreateRadial

Description

Creates a new radial gradient CairoPattern between the two circles defined by (cx0, cy0, radius0) and (cx1, cy1, radius1). Before using the gradient pattern, a number of color stops should be defined using cairoPatternAddColorStopRgb or cairoPatternAddColorStopRgba.

Usage

cairoPatternCreateRadial(cx0, cy0, radius0, cx1, cy1, radius1)

Value

[CairoPattern] the newly created CairoPattern if successful, or an error pattern in case of no memory.

This function will always return a valid pointer, but if an error occurred the pattern status will be set to an error. To inspect the status of a pattern use cairoPatternStatus.

Details

Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with cairoPatternSetMatrix.
