FADE(1)

NAME

fade - fade from one SGI image to another

SYNOPSIS

fade [-l loop] [-s steps] [-p pause] [-e shell_command]

from_image to_image

DESCRIPTION

Fade reads two image files, displays the first image, and fades to the second image. Both image files must be in SGI Image Library RGB format, and must be identical in size. If the -l argument is given, fade will alternately fade from one image to the other for loop times. The default value of loop is one. The -s argument specified the total number of frames displayed during the fade, including the starting and ending frames. As steps increases, the fade becomes smoother, but takes longer. The default value of steps is 40. The -p flag specifies the number of clock ticks to pause after a fade has completed, before proceeding to the next fade or exiting. The number of clock ticks per second is defined by the variable CLK_TCK in file <limits.h>. The default value of pause is zero. The -e argument specifies a shell command that is executed at the end of each frame. This is useful if one wished to record individual frame images (e.g., saving to videodisk with the videodisk(1) program).
