Detailed Description

Utility encoder using all other encoders within nkImages to parse arbitrary data.

This encoder's job is to delegate decoding to other encoders defined in the component. This means that for a given binary buffer, it will sequentially test it against all other encoders to select one that can decode the data into an image.
Cost is about looping into an array recording all encoders and calling their canDecode() method to know if data is compatible before calling the right decoding method.

Member Function Documentation

canDecode()

static bool nkImages::CompositeEncoder::canDecode ( nkMemory::BufferView< unsigned char >  data )

static

Checks whether the data provided can be decoded by one of the encoders available.

Parameters

data	The binary data to decode.

Returns

Whether the decoding is possible (true) or not (false).

decode()

static Image nkImages::CompositeEncoder::decode ( nkMemory::BufferView< unsigned char >  data, const AlignmentDescriptor &  alignmentDescriptor = AlignmentDescriptor()  )

static

Decodes a binary buffer into an image representation, by first finding which encoder is compatible with the data.

Parameters

data	The data to decode.
alignmentDescriptor	The memory alignment constraints, if any.

Returns

The decoded image if a compatible encoder could be found, an empty image else.
