Arguments

graphics_list	List containing pointers to window, renderer etc. created with CRopen.
rect_list	List defining multiple rectangles, containing vector elements x, y, w and h. (x[i], y[i], w[i], h[i]) together define one rectangle.
status	Optional list status with elements value and message to retrieve warnings and error messages.

Examples

    CRset_render_color(gs, list(r = 0, g = 0, b = 0))
    
    CRrender_clear(gs)
    
    CRset_render_color(gs, list(r = 100, g = 0, b = 0))
    
    rect_list <- list(x = c(50, 200, 100),
                      y = c(50, 50, 150),
                      w = c(50, 50, 150),
                      h = c(50, 70, 50))
    
    CRdraw_rects(gs, rect_list)
    
    CRrender_present(gs)
