Package: cairo
Function cairo:rel-line-to
Lambda Listcairo:rel-line-to (cr dx dy) ArgumentsDetails Relative-coordinate version of the cairo:line-to function.
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). 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 :no-current-point status. Notes | See also |
