In this article, we will see how we can access the opacity 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. Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc.
We can create a window with the help of the command given below
# creating a window window = pyglet.window.Window(width, height, title)
In order to create window we use opacity attribute with the shape
Syntax : shape.opacity
Argument : It takes no argument
Return : It returns integer
Below is the implementation
Python3
# importing pyglet module import pyglet# importing shapes from the pygletfrom pyglet import shapes# width of window width = 500 # height of window height = 500 # caption i.e title of the window title = "Geeksforneveropen" # creating a window window = pyglet.window.Window(width, height, title) # creating a batch objectbatch = pyglet.graphics.Batch()# properties of rectangle# co-ordinates of rectangleco_x = 150co_y = 150# width of rectanglewidth = 250# height of rectangleheight = 150# color = greencolor = (50, 225, 30)# creating a rectanglerec = 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 = redcolor = (255, 25, 25)# properties of circle# co-ordinates of circlecircle_x = 200circle_y = 300# size of circle# color = greensize_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.eventdef on_draw(): # clear the window window.clear() # draw the batch batch.draw() # accessing opacity of rectanglevalue_rec = rec.opacity# printing valueprint("Rectangle : ", end = "")print(value_rec)# accessing opacity of circlevalue_cir = circle.opacity# printing valueprint("Circle : ", end = "")print(value_cir)# run the pyglet applicationpyglet.app.run() |
Output :
