NAME

stream - a lightweight tool to stream one or more pixel components of the image or portion of the image to your choice of storage formats.

SYNOPSIS

stream [options] input-file output-file

OVERVIEW

Stream is a lightweight tool to stream one or more pixel components of the image or portion of the image to your choice of storage formats. It writes the pixel components as they are read from the input image a row at a time making stream desirable when working with large images or when you require raw pixel components.

For more information about the stream command, point your browser to file:///usr/share/doc/ImageMagick-6/www/stream.html or http://www.imagemagick.org/script/stream.php.

By default, the image format of `file' is determined by its magic number. To specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). Specify 'file' as '-' for standard input or output.
