示例1: readFromConnection
/**
* This helper function groups code to avoid duplication. It is not a member function of Image because
* there are problems with ImageNetworkHeader, anyhow the function is state-less and uses only parameters.
*/
inline bool readFromConnection(Image &dest, ImageNetworkHeader &header, ConnectionReader& connection)

dest.resize(header.width, header.height);
unsigned char *mem = dest.getRawImage();
