PNG writer class template. This is the low-level writing interface–use image class or generator class to actually write images.
The ostream
template parameter specifies the type of output stream to work with. The ostream
class should implement the minimum of the following interface:
{
public:
void write(char const*, size_t);
};
The PNG reader class template. This is the low-level reading interface–use image class or consumer cl...
Definition reader.hpp:67
With the semantics similar to the std::ostream
. Naturally, std::ostream
fits this requirement and can be used with the writer class as is.
