RGtk2 (version 2.8.7)

cairoPatternCreateRadial: cairoPatternCreateRadial

Description

Creates a new radial gradient cairo_pattern_t between the two circles defined by (x0, y0, c0) and (x1, y1, c0). 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 succesful, or an error pattern in case of no memory. The caller owns the returned object and should call cairo() when finished with it.

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.
