NAME

stream - Image Pixel FIFO

SYNOPSIS

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

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

FUNCTION DESCRIPTIONS

ReadStream

Method 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:

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

A description of each parameter follows:

status:

Method ReadStream returns True if the image pixels are streamed to the user supplied callback method otherwise False.

image_info:

Specifies a pointer to an ImageInfo structure.

stream:

a callback method.

exception:

return any errors or warnings in this structure.

WriteStream

Method 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:

status:

Method WriteStream returns True if the image pixels are streamed to the user supplied callback method otherwise False.

image_info:

Specifies a pointer to an ImageInfo structure.

stream:

a callback method.
