Cross-platform text rendering in pygame with AGG

 / Published in: Python
 

A quick first test case in which I use aggdraw for rendering text to a pygame Surface. Pygame's font-rendering doesn't work properly cross-platform, and this looks promising. I'll need to integrate the AGG canvas more tightly with the pygame Surface, but I think it'll work out.

Expand | Embed | Plain Text 
  1. import aggdraw as ag
  2. import pygame as pg
  3.  
  4. class TextPainter(Painter):
  5.     def __init__(self, text, *args, **kwds):
  6.         Painter.__init__(self, *args, **kwds)
  7.         self.text = text
  8.         self.canvas = ag.Draw("RGB", (self.width, self.height),
  9.           ColourScheme.background)
  10.         self.font = ag.Font(ColourScheme.text,
  11.           os.path.join("..", "gfx", "slkscr.ttf"), 8)
  12.         self.canvas.text((0, 0), self.text, self.font)
  13.         self.surf = pg.image.fromstring(self.canvas.tostring(),
  14.           (self.width, self.height), "RGB")
  15.         self.window = Window()
  16.         self.window.addPainter(self)
  17.  
  18.     def paint(self):
  19.         self.window.blit(self.surf, (self.xPos, self.yPos))
