cairoPatternCreateRadial {RGtk2} | R Documentation

## 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)

### 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 circle
``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 circle

### 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`.

### 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`.
