-
-sprites.py is a simple sprites library for managing graphics objects,
-'sprites', on a gtk.DrawingArea. It manages multiple sprites with
-methods such as move, hide, set_layer, etc.
-
-There are two classes:
-
-class Sprites maintains a collection of sprites
-class Sprite manages individual sprites within the collection.
-
-Example usage:
-        # Import the classes into your program.
-        from sprites import Sprites Sprite
-
-        # Create a new sprite collection associated with your widget
-        self.sprite_list = Sprites(widget)
-
-        # Create a "pixbuf" (in this example, from SVG).
-        my_pixbuf = svg_str_to_pixbuf("<svg>...some svg code...</svg>")
-
-        # Create a sprite at position x1, y1.
-        my_sprite = sprites.Sprite(self.sprite_list, x1, y1, my_pixbuf)
-
-        # Move the sprite to a new position.
-        my_sprite.move((x1+dx, y1+dy))
-
-        # Create another "pixbuf".
-        your_pixbuf = svg_str_to_pixbuf("<svg>...some svg code...</svg>")
-
-        # Create a sprite at position x2, y2.
-        your_sprite = sprites.Sprite(self.sprite_list, x2, y2, my_pixbuf)
-
-        # Assign the sprites to layers.
-        # In this example, your_sprite will be on top of my_sprite.
-        my_sprite.set_layer(100)
-        your_sprite.set_layer(200)
-
-        # Now put my_sprite on top of your_sprite.
-        my_sprite.set_layer(300)
-
-        cr = self.window.cairo_create()
-        # In your activity's do_expose_event, put in a call to redraw_sprites
-        self.sprites.redraw_sprites(event.area, cairo_context)
-
-# method for converting SVG to a gtk pixbuf
-def svg_str_to_pixbuf(svg_string):
-    pl = gtk.gdk.PixbufLoader('svg')
-    pl.write(svg_string)
-    pl.close()
-    pixbuf = pl.get_pixbuf()
