In this article we will see how we can draw arc on window 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). An arc is a portion of the circumference of a circle. In the figure above, the arc is the blue part of the circle. Strictly speaking, an arc could be a portion of some other curved shape, such as an ellipse, but it almost always refers to a circle. Arc is drawn with the help of shapes module in 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 Arc method with pyglet.shapes
Syntax : shapes.Arc(arc_x, arc_y, size_arc, segments, angle, color, batch=batch)
Argument : It takes first two integer i.e arc position, third integer as size, fourth is integer i.e segments, fifth is float i.e angle, sixth is color and last is batch object
Return : It returns Arc object
Below is the implementation
# 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 circle # co-ordinates of circle arc_x = 250
arc_y = 250
# size of arch size_arc = 100
# segments segments = 5
# angle angle = 20
# color = green color = ( 50 , 225 , 30 )
# creating a arc arc1 = shapes.Arc(arc_x, arc_y, size_arc, segments, angle, color, batch = batch)
# changing opacity of the arc1 # opacity is visibility (0 = invisible, 255 means visible) arc1.opacity = 250
# creating another circle with other properties # new position = circle1_position - 50 # new size = previous radius -20 # new color = red color = ( 255 , 30 , 30 )
# increase segments segments = 10
# decreasing angle angle = 7
# creating another arc arc2 = shapes.Arc(arc_x - 50 , arc_y - 50 , size_arc - 20 , segments, angle, color, batch = batch)
# changing opacity of the arce2 arc2.opacity = 255
# window draw event @window .event
def on_draw():
# clear the window
window.clear()
# draw the batch
batch.draw()
# run the pyglet application pyglet.app.run() |
Output :
