PYGLET – Shape Anchor Position

In this article we will see how we can get the anchor position of the shape in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material type. Many shapes are drawn with the help of shapes module of pyglet.
We can create a window with the help of command given below 

# creating a window
window = pyglet.window.Window(width, height, title)

In order to create window we use anchor_position attribute with the shape
Syntax : shape.anchor_position
Argument : It takes no argument
Return : It returns tuple 

Below is the implementation 

Python3

# importing pyglet module
import pyglet

# importing shapes from the pyglet
from pyglet import shapes

# width of window
width = 500

# height of window
height = 500

# caption i.e title of the window
title = "Geeksforgeeks"

# creating a window
window = pyglet.window.Window(width, height, title)

# creating a batch object
batch = pyglet.graphics.Batch()


# properties of rectangle
# co-ordinates of rectangle
co_x = 150
co_y = 150

# width of rectangle
width = 250

# height of rectangle
height = 150

# color = green
color = (50, 225, 30)

# creating a rectangle
rec = shapes.Rectangle(co_x, co_y, width, height, color = color, batch = batch)

# changing opacity of the rect1
# opacity is visibility (0 = invisible, 255 means visible)
rec.opacity = 180


# creating another rectangle with properties
# x, y co ordinate : 50, 250
# width, height of rectangle : 300, 200
# color = red
color = (255, 25, 25)

# properties of circle
# co-ordinates of circle
circle_x = 200
circle_y = 300

# size of circle
# color = green
size_circle = 100

# creating a circle
circle = shapes.Circle(circle_x, circle_y, size_circle, color =(250, 22, 30), batch = batch)

# changing opacity of the circle1
# opacity is visibility (0 = invisible, 255 means visible)
circle.opacity = 170


# window draw event
@window.event
def on_draw():

    # clear the window
    window.clear()

    # draw the batch
    batch.draw()


# accessing anchor position of rectangle
value_rec = rec.anchor_position

# printing value
print("Rectangle : ", end = "")
print(value_rec)

# accessing anchor position of circle
value_cir = circle.anchor_position

# printing value
print("Circle : ", end = "")
print(value_cir)



# run the pyglet application
pyglet.app.run()

Output :

Rectangle : (0, 0)
Circle : (0, 0)
