NAME    [Toc]    [Back]

     compview -	tool for viewing results of compression

SYNOPSIS    [Toc]    [Back]

     compview [	-q quality ] [ -hw ] [ -nofork ]

DESCRIPTION    [Toc]    [Back]

     comvpiew provides a graphical interface to	view an	image and the
     result of compressing the image with either sofware or hardware
     JPEG while	interactively setting the quality factor of the	compressed
     image.  The size of the original image, the size of the compressed
     image, and	the compression	ratio are displayed.  As an option the
     compresses/decompress cycle can be	performed multiple times, with
     the resulting image then displayed.

     compview also provides panels to view the difference between the
     original and the compressed image along with the mean squared error,
     to	provide	information about the original image, and to view close-ups
     of	either image.  These panels are	updated	automatically as the
     quality factor is adjusted.

OPTIONS    [Toc]    [Back]

     -q	quality
	   Initializes the quality factor to be	quality.

     -hw   Initializes the compressor to be hardware JPEG (default is
	   software JPEG).

     -nofork
	   Do not go into the background.  By default, compview	forks
	   itself to give control back to the shell.
