The name of the format specifies the data type of the component, the number of

values, and whether the data is normalized.

* `uchar` = unsigned 8-bit value

* `char` = signed 8-bit value

* `ushort` = unsigned 16-bit value

* `short` = signed 16-bit value

* `half` = half-precision 16-bit floating point value

* `float` = 32-bit floating point value

* `uint` = unsigned 32-bit integer value

* `int` = signed 32-bit integer value

If no number of values is given in the name, a single value is provided.

If the format has the `-bgra` suffix, it means the values are arranged as

blue, green, red and alpha values.
