WHAT IS XLI ?

	xli is a multiformat bitmap image viewer for X11 displays
(and MSDOS systems that run DJGPP) It is command line driven
and provides a fast, robust and high quality method of viewing
images, or loading them onto the root window.  It has a variety
of options to fine tune viewing or create image loops etc. It
automatically decodes uu encoded files and compressed (.Z) files.

It supports all X11 visuals, and will display 24 bit pictures in
true color on an appropriate display. Unlike nearly all other
popular viewers, it gamma corrects images appropriately for the
display CRT before displaying them, giving correct image contrast.

The current version (1.15) supports:

	CMU Window Manager raster files
	Faces Project images
	Fuzzy Bitmap (.fbm) images
	GEM bit images
	GIF images (Including GIF89a compatibility)
	G3 FAX images
	JFIF style jpeg images
	McIDAS areafiles
	MacPaint images
	Monochrome PC Paintbrush (.pcx) images
	Portable Bitmap (.pbm, .pgm, .ppm) images
	Sun monochrome rasterfiles
	Sun color RGB rasterfiles
	Targa (.tga) files
	Utah Raster Toolkit (.rle) files
	X pixmap (.xpm) files (Version 1, 2C and 3)
	X10 bitmap files
	X11 bitmap files
	X Window Dump (except TrueColor and DirectColor)

A variety of options are available to modify images prior to viewing.
These options include clipping, dithering, depth reduction, zoom
(either X or Y axis independently or both at once), brightening or
darkening, input image gamma correction, and image merging.  When applicable,
these options are done automatically (eg. a color image to be displayed
on a monochrome screen will be dithered automatically). A utility (xlito)
is provided that allows these viewing options to be attached to the image
files.

It is possible to interactively adjust image contrast (gamma).

HOW IS XLI RELATED TO XLOADIMAGE ?

    xli version 1.00 was based on xloadimage version 3.01,
    and retains option compatibility with it.

WHAT IMPROVEMENTS ARE IN VERSION 1.15 over 1.14a ?

    Added Targe (TGA) image support.
	Fixed up gif reader to cope with GIF89a format.
    Added -fillscreen option.
    Improved color handling so that default colormap colors are
    re-used (reduces flashing).
    Added interactive gamma (brightness) adjustment.
    Did initial port to MSDOS, based on djgcc 1.09 environment.
    Some speedups in color reduction and colormap compression.
