cairo_rel_line_to: cairo_rel_line_to

In coolbutuseless/cairocore: Low-Level Cairo Bindings

Description

Relative-coordinate version of cairo_line_to(). 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

cairo_rel_line_to(cr, dx, dy)

Arguments

cr	[cairo_t *] a cairo context
dx	[double] the X offset to the end of the new line
dy	[double] 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.

Since: 1.0

C function prototype: void cairo_rel_line_to (cairo_t *cr, double dx, double dy)
