In this article we will see how we can get all the font used in the formatted document 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). Formatted documents are generally laid out to enhance their human readability by adding structure, such as headings, indentation, font variations, and other devices that transform plain (unformatted) text so that they have an appearance similar to published works. In metal typesetting, a font was a particular size, weight and style of a typeface. Each font was a matched set of type, one piece for each glyph, and a typeface consisting of a range of fonts that shared an overall design.
We can create a window and formatted document with the help of commands given below
# creating a window window = pyglet.window.Window(width, height, title) # creating document document = pyglet.text.document.FormattedDocument(text)
In order to create window we use get_font_runs method with the document object
Syntax : document.get_font_runs()
Argument : It takes no argument
Return : It returns AbstractRunIterator
Below is the implementation
Python3
# importing pyglet moduleimport pygletimport pyglet.window.key# width of windowwidth = 500# height of windowheight = 500# caption i.e title of the windowtitle = "Geeksforneveropen"# creating a windowwindow = pyglet.window.Window(width, height, title)# text text = "Welcome to neveropen Have a nice day"# batch objectbatch = pyglet.graphics.Batch()# creating a formatted documentdocument = pyglet.text.document.FormattedDocument(text)# setting style to the documentdocument.set_style(0, len(document.text), dict( font_name ='Arial', font_size = 16, color =(255, 255, 255, 255)))# creating a incremental text layoutlayout = pyglet.text.layout.IncrementalTextLayout( document, 400, 350, batch = batch)# creating a caretcaret = pyglet.text.caret.Caret(layout, color =(150, 255, 150))# caret to window push handlerswindow.push_handlers(caret)# setting caret stylecaret.set_style(dict(font_name ="Arial"))# on draw event@window.eventdef on_draw(): # clear the window window.clear() # draw the batch batch.draw() # caret to window push handlers window.push_handlers(caret) # key press event @window.eventdef on_key_press(symbol, modifier): # key "C" get press if symbol == pyglet.window.key.C: # closing the window # window.close() pass # image for iconimg = image = pyglet.resource.image("logo.png")# setting image as iconwindow.set_icon(img)# getting all the font in the documentvalue = document.get_font_runs()# printing valueprint("Fonts : ", end = " ")print(value)# start running the applicationpyglet.app.run() |
Output :
Fonts : pyglet.text.document._FontStyleRunsRangeIterator object at 0x000001E95DC52308
