Detailed Description

The ColorFormatDecoder allows for easy conversion of special color formats to RGB.

If a capturing device does not support to provide RGB image directly, this Decoder is usually used to convert the compressed image data into a simple planar RGB image (core::Img8u). However, also other output core::depth value are supported.
The decoding routine, is chosen by analyising the source data based on its fourcc color code (see: http://en.wikipedia.org/wiki/FourCC and http://v4l2spec.bytesex.org/spec/c2030.htm for more details)

Example

For supporting the Myrmex Tactile Device, we added an extra FourCC code called "MYRM".
