cairoArcNegative {RGtk2} | R Documentation

## cairoArcNegative

### Description

Adds a circular arc of the given `radius` to the current path. The arc is centered at (`xc`, `yc`), begins at `angle1` and proceeds in the direction of decreasing angles to end at `angle2`. If `angle2` is greater than `angle1` it will be progressively decreased by 2*M_PI until it is less than `angle1`.

### Usage

    cairoArcNegative(cr, xc, yc, radius, angle1, angle2)

### Arguments

``cr`` | [`Cairo`] a cairo context
``xc`` | [numeric] X position of the center of the arc
``yc`` | [numeric] Y position of the center of the arc
``radius`` | [numeric] the radius of the arc
``angle1`` | [numeric] the start angle, in radians
``angle2`` | [numeric] the end angle, in radians

### Details

See `cairoArc` for more details. This function differs only in the direction of the arc between the two angles.
