[MapProxy] Differing X and Y Tile Resolutions

[Napoleon, Dominic]

Hello,


Can MapProxy support differing x and y resolutions?  For example, GeoPackage caches support differing x and y resolutions when defining the pixel_x_size and pixel_y_size values in the gpkg_tile_matrix table.


It seems that in _verify_tile_size in geopackage.py, this line of code:

if not is_close(gpkg_pixel_x_size, resolution) or not is_close(gpkg_pixel_y_size, resolution):

...is essentially checking to make sure the x and y resolutions match.  If they don't, it throws an error.  There doesn't seem to be away to specify differing x and y resolutions in a configuration's grid.


I ask because MapProxy can't properly transform the tiles in a cache with differing x and y resolutions, in this case meaning MapProxy isn't fully supporting the GeoPackage spec.


Best,
