    We have a large PNG image that represents a marine chart, this displays as a layer successfully using the UirImageProvider but not at its native resolution which is between zoom level 5 and 6.  At level 5 it is slightly 'shrunken' and at level 6 it is slightly 'zoomed in'.

    How do you display the layer at its native resolution?

    Hello John Howe,

    Please, check that geographical bounds (GeoBounds, or GeoBoundsNW and GeoBoundsSE properties) are set precisely for UriImageProvider. It resizes images to the correspondent zoom level quite well.

    There is no way to show image at its native resolution if pixel size of the image does not corresponds to the pixel size of the covered geographical region at the specified zoom level.
