CommonCodecs

This toolbox contains a list of commonly used codecs for encoding and decoding data using a mira::BinarySerializer and mira::BinaryDeserializer .

Currently there exist 4 codecs for encoding images:

mira::codec::JpegCodec encoding images as JPEG (Parameter "Quality" 0: highest compression, 100: best quality, default: 95)
mira::codec::PngCodec encoding images as PNG (Parameter "Compression" 0: lowest but fastest, 9: best but slowest, default: 3)
mira::codec::Z11Codec lossless compression of 11 bit depth images
mira::codec::Z16TableCodec lossless compression of 16 bit depth images

Example for serializing data with JPEG Codec:

Buffer<uint8> buf;
BinaryBufferSerializer serializer(&buf);
// add a JpegCodec to the serializer
serializer.registerCodec(BinarySerializerCodecPtr(new JpegCodec(95)));
Img8U3 img;
...
// serialize the image using the JpegCodec
serializer.serialize(img); 

Example for deserializing encoded data

Buffer<uint8> buf;
... load encoded data into buf
BinaryBufferDeserializer deserializer(&buf);
Img8U3 img;
...
// deserialize the image (JpegCodec will be used automatically if necessary)
serializer.serialize(img); 

Please note, that for the deserialization no special handling is necessary. If the deserializer detects encoded data, it will automatically use the correct codec (that is identified by the FOURCC code) to decode the data.
