NAME

xdl - display DL animations in an X window.

SYNOPSIS

xdl [-h] [-z] [-r frames/second] [file]

DESCRIPTION

Xdl reads a file in DL format and displays the animation in that file in an X window. The DL file is read from either the standard input or the specified file. The program can be run on monochrome (1 bit per pixel), colormapped (8 bits per pixel) and full color (24 bits per pixel) systems. On monochrome systems the images is halftoned with the Floyd-Steinberg algorithm.

OPTIONS

-h: Write some help about how the program should be started.
-z: If the animation is in medium format (160 x 100) it will be zoomed up to large format (320 x 200). If run on a color display the zoom operation is simple nearest neighbour, on a monochrome display some smoothing will be performed. If the animation is in large format this switch will be ignored.
-r frames/second: Determines the rate of the animation, ie how many frames per second that should be displayed. The minimum is 2 and the default is 25. The given rate is a maximum.

EXAMPLES

Display the animation foo.dl at 25 frames per second.

: xdl foo.dl

Display the animation fie.dl, zoomed to large format, at 12 frames per second.

: xdl -z -r 12 fie.dl

BUGS

There should be smoothing when zooming in color also.

The program talks too much, a -quiet flag should be added.

The code is unreadable.

The program is derived from dltogl by George Phillips <phillips@cs.ubc.ca>

The suggestion (and code) to allow the user to set the animation rate came from Per Beremark <per.beremark@telelogic.se>
