Public Functions Documentation

function Decode

virtual bool drift::img::IImageCodec::Decode (
    const std::string & blob,
    SignalN2D * image,
    size_t start_channel=0
) const = 0

Decodes a picture from a string to blaze matrices

Parameters:

• blob the string with the picture in some image format
• image a pointer to decoded blaze image
• start_channel

Returns:

false if there is an error

function Encode

virtual bool drift::img::IImageCodec::Encode (
    const SignalN2D & image,
    std::string * blob,
    size_t start_channel=0
) const = 0

Encodes a blaze image to string in some image format

Parameters:

• image the blaze image to encoded
• blob an encoded string
• start_channel

Returns:

false if there is an error

function channel_number

virtual size_t drift::img::IImageCodec::channel_number () const = 0

function checkChannelsShape

virtual bool drift::img::IImageCodec::checkChannelsShape (
    const SignalN2D & image,
    size_t start_channel
) const = 0

function ~IImageCodec

virtual drift::img::IImageCodec::~IImageCodec () = default
