In this article, we will see how we can draw line 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). Spectral line shape describes the form of a feature, observed in spectroscopy, corresponding to an energy change in an atom, molecule or ion. Ideal line shapes include Lorentzian, Gaussian and Voigt functions, whose parameters are the line position, maximum height and half-width. Line 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 Line method with pyglet.shapes
Syntax : shapes.Line(co_x1, co_y1, co_x2, co_y2, width, color = (50, 225, 30), batch=batch)
Argument : It takes starting and end position in form of pair of two integers, width of line, color of line and last is batch object
Return : It returns Line object
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 = "GeeksforLazyroar" # creating a window window = pyglet.window.Window(width, height, title) # creating a batch objectbatch = pyglet.graphics.Batch()# properties of line# first co-ordinates of lineco_x1 = 150co_y1 = 150# second co-ordinates of lineco_x2 = 350co_y2 = 350# width of linewidth = 10# color = greencolor = (50, 225, 30)# creating a lineline1 = shapes.Line(co_x1, co_y1, co_x2, co_y2, width, color = (50, 225, 30), batch = batch)# changing opacity of the line1# opacity is visibility (0 = invisible, 255 means visible)line1.opacity = 250# creating another line with properties# x1, y1 = 50, 250# x2, y2 = 400, 250# color = redline2 = shapes.Line(50, 250, 400, 250, 30, color = (250, 30, 30), batch = batch)# changing opacity of the line2# opacity is visibility (0 = invisible, 255 means visible)line2.opacity = 100# window draw event@window.eventdef on_draw(): # clear the window window.clear() # draw the batch batch.draw()# run the pyglet applicationpyglet.app.run() |
Output :
