cairoRelLineTo {RGtk2} | R Documentation

## cairoRelLineTo

### Description

Relative-coordinate version of `cairoLineTo`. Adds a line to the path from the current point to a point that is offset from the current point by (`dx`, `dy`) in user space. After this call the current point will be offset by (`dx`, `dy`).

### Usage

    cairoRelLineTo(cr, dx, dy)

### Arguments

``cr`` | [`Cairo`] a cairo context
``dx`` | [numeric] the X offset to the end of the new line
``dy`` | [numeric] the Y offset to the end of the new line

### Details

Given a current point of (x, y), cairo_rel_line_to(`cr`, `dx`, `dy`) is logically equivalent to cairo_line_to(`cr`, x + `dx`, y + `dy`).

It is an error to call this function with no current point. Doing so will cause `cr` to shutdown with a status of `CAIRO_STATUS_NO_CURRENT_POINT`.
