How to use Pyramidal TIFFs plugin

[bchiavarini]

Hi to everyone,
i am trying to display a geotiff file on a globeview using the itowns Pyramidal TIFFs plugin. I read that the single TIFF display on the globeview is not supported but only pyramidal TIFF, so i created a pyramidal TIFF of my data and i used the itowns.TMSSource function to load it as seen on this example: https://github.com/iTowns/itowns/blob/master/examples/plugins_pyramidal_tiff.html.

The result is a tile not positioned according its coordinates origin and not having the expected dimension to cover its bounding box coordinates but covering half the globe like the image in attach:

My pyramidal geotiff contains georeferenced data regarding a specific portion of a globe (to be more specific a region in Europe) and not data regarding the whole globe (like the data used in the example and available at https://raw.githubusercontent.com/iTowns/iTowns2-sample-data/master/geoid/localcolors/tiff/ folder). I would like to ask if it is supported the displaying of pyramydal TIFFs covering a single portion of a globe or if this plugin is intended only for pyramidal tiff covering the whole globe. If this is the case, is there a possibility to display geotiff data related to a specific bounding box?

Thanks in advance to anyone who will help me!
