def tcoords_pixel_scaled(self):
r"""
Returns a :map:`PointCloud` that is modified to be suitable for directly
indexing into the pixels of the texture (e.g. for manual mapping
operations). The resulting tcoords behave just like image landmarks
do.
The operations that are performed are:
- Flipping the origin from bottom-left to top-left
- Scaling the tcoords by the image shape (denormalising them)
- Permuting the axis so that
Returns
-------
tcoords_scaled : :map:`PointCloud`
A copy of the tcoords that behave like :map:`Image` landmarks
Examples

Recovering pixel values for every texture coordinate:

>>> tc_ps = texturedtrimesh.tcoords_pixel_scaled()
>>> pixel_values_at_tcs = texture.sample(tc_ps)
