Hello. I'm sorry about the formatting of my last mail, I didn't
realize my client was set that way.
Here's the contents of that email:
Hello all, I'm confused about TextureGrid. I'm creating one from an
ImageGrid, and what I expect is that my image will be chopped into texture
tiles, so that each element in the TextureGrid is a quadrant of my image.
The image I'm using is 512x512. What I thought I would see was the
bottom-left 256x256 corner of the window matching the bottom-left 256x256 of
the image, while the rest of the window would be the black default clear
color.
I'm on python 2.6, vista, pyglet 1.1.3.
Here's a minimal version of the code:
import pyglet
from pyglet.gl import *
class MainWindow(pyglet.window.Window):
def __init__(self, *args, **kwargs):
pyglet.window.Window.__init__(self, *args, **kwargs)
img = pyglet.image.load("small_background.png")
self.grid = pyglet.image.ImageGrid(img, 2, 2)
self.txgrid = self.grid.get_texture_sequence()
def on_draw(self):
verts = [0.0, 0.0, 256.0, 256.0]
tex = self.txgrid[0, 0]
glEnable(tex.target)
glBindTexture(tex.target, tex.id)
glBegin(GL_QUADS)
glTexCoord2f(0.0, 0.0)
glVertex3f(verts[0], verts[1], 0.5)
glTexCoord2f(1.0, 0.0)
glVertex3f(verts[2], verts[1], 0.5)
glTexCoord2f(1.0, 1.0)
glVertex3f(verts[2], verts[3], 0.5)
glTexCoord2f(0.0, 1.0)
glVertex3f(verts[0], verts[3], 0.5)
glEnd()
if __name__ == '__main__':
w = MainWindow(512, 512)
pyglet.app.run()
