cairoSetSourceRgb {RGtk2} | R Documentation

## cairoSetSourceRgb

### Description

Sets the source pattern within `cr` to an opaque color. This opaque color will then be used for any subsequent drawing operation until a new source pattern is set.

### Usage

    cairoSetSourceRgb(cr, red, green, blue)

### Arguments

``cr`` | [`Cairo`] a cairo context
``red`` | [numeric] red component of color
``green`` | [numeric] green component of color
``blue`` | [numeric] blue component of color

### Details

The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped.

The default source pattern is opaque black, (that is, it is equivalent to cairo_set_source_rgb(cr, 0.0, 0.0, 0.0)).
