Capabilities
============

Different camera models has different limitations. The *capabilities* API allows you to inspect limitation and features of the connected camera.

Though this feature is introduced in 3.0, it does not define many API's. It is intended to be built upon in future releases.

Maximum Pixels in a Tile
^^^^^^^^^^^^^^^^^^^^^^^^

This is the currently only limitation defined by the *Capabilities API*.

Cameras has limited RAM, and therefore has a maximum size they can scale *tiles* to. (Remember *tiles* is part of the *Image Browsing* feature set. See: :ref:`getting-a-tile-label`.)

This number defines the total amount of pixels that can be in a tile, meaning it is the product of the tile's *width* and *height*: ``maxPixels >= width * height``.

Future camera model might include more RAM, and might therefore have a higher upper limit of this value.
