so, i may have made my reply too fast. mattis n, this works and is tested
on my system.
from pyglet.gl import *
import pyglet
def make_pixelated(sprite):
""" Make the goup of this sprite pixelated.
:param sprite: pyglet.sprite.Sprite
:return: None
"""
import types
def set_state(self):
glEnable(self.texture.target)
glBindTexture(self.texture.target, self.texture.id)
glPushAttrib(GL_COLOR_BUFFER_BIT)
glEnable(GL_BLEND)
glTexParameteri(self.texture.target, GL_TEXTURE_MAG_FILTER, GL_NEAREST)
glBlendFunc(self.blend_src, self.blend_dest)
group = sprite._group
group.set_state = types.MethodType(set_state, group)
window = pyglet.window.Window()
image = pyglet.image.load("gold.jpg")
batch = pyglet.graphics.Batch()
sprite = pyglet.sprite.Sprite(image, batch=batch)
make_pixelated(sprite)
sprite.scale = 2
@window.event
def on_draw():
window.clear()
batch.draw()
pyglet.app.run()
I missed the part where it isn't the sprite that sets the state, it is the
group that it belongs to. What you see above is a hack that adds our
'pixelated render' to the group that renders the sprite. The correct was
of doing this isn't super obvious, due to how groups are created. this is
just works easier.
