Problem with PixelTexture

Hello,

I've a big problem with PixelTexture ...
I'll try to make my question simple & distinct :

How can I apply a PixelTexture{} onto a Shape{},
- with no repetitions (each pixel corresponds to ONE region of the Shape)
- with a texturing of the complete Shape{} (no blank region)

If somebody knows ... :-/

Thank you,
O.L.

For this questions, it makes no difference, if you talk about PixelTexture
or ImageTexture.

In general you need a geometry in your shape, that supports
TextureCoordinates and you need to set this TextureCoordinates depending
from your geometry to solve your requests.

Yes, but the TextureCoordinate makes the VRML file bigger, and it's
difficult to use, I think.
In fact I tried to texture an avatar, so I put a PixelTexture with repeatS
and repeatT FALSE ont it. But when I drawed something on the avatar's
torso, it appeared in his back too !
So I cut it in several parts : right leg, left leg, right arm, etc. and I
put one PixelTexture for each body part. And it worked. But ... I don't
understand how a texture can be visible on more than one region of a Shape
{}, with repeatS and T FALSE ..... :-S
