Package: curser
DESCRIPTIONcurser is a python module based and complementary to pygame,
who will give you analog functions as the turtle module implement
in a pygame display to make easier the generation and the animation of
forms like polygons, spirals, fractals and so soon.
With abstraction of the coordinates computing throught an curser object,
analog to the turtle, whose orientation is setable throught rotation functions
to the left or to the right from the number of wanted degrees with progressiv
animated stroke drawing or not animated functions whose color and width are
configurable.Instanciate the Curser class with the following arguments:start_x:the start x coordinate from the curser start position.start_y:the start y coordinate from the curser start position.start_angle (default = 0)  :the start orientation from the curser.color (default = (0, 0, 0)):the stroke and curser color given as a 3-elements tuple (red,green,blue).bg_color (default = (255, 255, 255)):the display background color given as a 3-elements tuple (red,green,blue).stroke_width (default = 1):the stroke width in pixel(s) given as an integer.curser_down (default = True):a boolean value if the curser is down.to get an curser object who implement the following methods:The module curser implement following functions for the displaying
of the curser, the strokes attributes and the background display screen:show_curser()Show the curser but does not put him down.! The curser is visible per default.hide_curser()Hide the curser but does not raise him up,
is simply to hide the curser for driving.set_stroke_color(color)set stroke and curser color to the argument color
who must be an 3-elements tuple (red,green,blue)set_stroke_width(stroke_width)set the stroke width to the stroke_width argument in pixels.! The curser size will increase or decrease
if you change the stroke width.set_bg_color(bg_color)Change the display background.! You have to set the show_hook() method in the
mainloop to make it effectiv if you work with it.The module curser implement following curser control functions
for the turtle curser control:curser_up()Raise the curser up and any curser moving method will not
draw but the direction changings are effectiv.! This method does not hide the curser.curser_down()Put the curser down any moving method will draw on the display.! This method do not show the curser if he is hidden.set_curser_pos(x,y)Set the curser position to the coordinates x,y.The module curser implement following turtle moving and orientation functions:mv_forward(px)Move the curser forward in the current direction from px pixels.mv_backward(px)Move the curser backward in the opposite direction to the current from px pixels.mv_left(degrees)Turn the curser left from argument degrees degrees and update the current direction.mv_right(degrees)Turn the curser right from argument degrees degrees and update the current direction.anim_forward(px,speed)Move the curser forward in current direction from one pixel every speed seconds (or fraction) from px pixels far what create an stroke drawning animation effect.anim_backward(px,speed)move the curser backward in the opposite direction from one pixel every speed seconds (or fraction) from px pixels far what create an stroke drawning animation effect.The module curser implement following functions for use of personnalized
coordinates container(s) giving you the control for the displayed forms were
you can use to store your forms coordinates:get_coords_forward(px)Return the coordinates for a forward moving result from px pixels without drawing a stroke or move the curser.! Use this method with your own coordinates container.get_coords_backward(px)Return the coordinates for a backward moving result from px pixels without drawing a stroke or move the curser.! Use this method with your own coordinates container.get_curser_pos()return the current curser position as (x,y).Import the module with the import directive:###########################################################################

the turtle module for pygame.Some examples scripts are deliver with the module to show you the power of curser.
