# FUNCTION DESCRIPTIONS

## ReadStream

> ReadStream() makes the image pixels available to a user supplied callback method immediately upon reading a scanline with the ReadImage ( ) method.

> The format of the ReadStream() method is:

> Image *ReadStream ( const ImageInfo *image_info, void ( *Stream ) ( const Image *, const void *, const size_t ), ExceptionInfo *exception );

    Return any errors or warnings in this structure.

## WriteStream

> WriteStream() makes the image pixels available to a user supplied callback method immediately upon writing pixel data with the WriteImage ( ) method.

> The format of the WriteStream() method is:

> unsigned int WriteStream ( const ImageInfo *image_info, Image *, int ( *Stream ) ( const Image *, const void *, const size_t ) );

A description of each parameter follows:

  image_info:
