sdlRenderDrawLineF function

int sdlRenderDrawLineF(
  1. Pointer<SdlRenderer> renderer,
  2. double x1,
  3. double y1,
  4. double x2,
  5. double y2,
)

Draw a line on the current rendering target at subpixel precision.

\param renderer The renderer which should draw a line. \param x1 The x coordinate of the start point. \param y1 The y coordinate of the start point. \param x2 The x coordinate of the end point. \param y2 The y coordinate of the end point. \return 0 on success, or -1 on error

\since This function is available since SDL 2.0.10.
