Error when generating/saving some normalised poses

[Tilia Ellendorff]

There is an occasional issue for some pose files when saving a normalized version of the hands.

Error message: ushort format requires 0 <= number <= (32767 *2 +1)

A pose file is generated but it is very small (only 4 bytes) and it cannot be read in again.

Currently, I have only seen this issue with normalisation of the right hand.

The problem seems to be your dimensions.
They are:

width=72165 
height=53412 
depth=7497

To fix this, for your case, you can set the dimensions to something else. Here is the maximum value:

p_norm_rh.header.dimensions.width = 0x7fff * 2 + 1
p_norm_rh.header.dimensions.height = 0x7fff * 2 + 1
p_norm_rh.header.dimensions.depth = 0x7fff * 2 + 1

Please note, this does not have an effect on the pose data, but only matters for visualization, if you would like to draw the pose it will create an insanely large image. (So you could also use 0 and that would be fine)

I now added warnings in 2bd9d2f

Does this solve your issue?
