cairoMatrixRotate {RGtk2} | R Documentation

## cairoMatrixRotate

### Description

Applies rotation by `radians` to the transformation in `matrix`. The effect of the new transformation is to first rotate the coordinates by `radians`, then apply the original transformation to the coordinates.

### Usage

    cairoMatrixRotate(matrix, radians)

### Arguments

``matrix`` | [`CairoMatrix`] a `CairoMatrix`
``radians`` | [numeric] angle of rotation, in radians. The direction of rotation is defined such that positive angles rotate in the direction from the positive X axis toward the positive Y axis. With the default axis orientation of cairo, positive angles rotate in a clockwise direction.
