RGtk2 (version 2.8.8)

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)

Arguments

cx0

[numeric] x coordinate for the center of the start circle

cy0

[numeric] y coordinate for the center of the start circle

radius0

[numeric] radius of the start cirle

cx1

[numeric] x coordinate for the center of the end circle

cy1

[numeric] y coordinate for the center of the end circle

radius1

[numeric] radius of the end cirle

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.

  [object Object] internal

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.
