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 = GdkPixbuf.PixbufLoader('svg')

pl.write(svg_string)

pl.close()

pixbuf = pl.get_pixbuf()

return pixbuf
