NAME
xwud - image displayer for X
SYNOPSIS
xwud [-in file] [-noclick] [-geometry geom] [-display display] [-new]
[-std <maptype>] [-raw] [-vis <vis-type-or-id>] [-scale] [-help] [-rv]
[-plane number] [-fg color] [-bg color] [-dumpheader]
DESCRIPTION
Xwud is an X Window System image undumping utility. Xwud allows X
users to display in a window an image saved in a specially formatted
dump file, such as produced by xwd(1).
OPTIONS
-bg color
If a bitmap image (or a single plane of an image) is displayed,
this option can be used to specify the color to display for the
"0" bits in the image.
-display display
This option allows you to specify the server to connect to; see
X(7).
-dumpheader
This option prints out the XWD header information only.
Nothing is displayed.
-fg color
If a bitmap image (or a single plane of an image) is displayed,
this option can be used to specify the color to display for the
"1" bits in the image.
-geometry geom
This option allows you to specify the size and position of the
window. Typically you will only want to specify the position,
and let the size default to the actual size of the image.
-help Print out a short description of the allowable options.
-in file
This option allows the user to explicitly specify the input
file on the command line. If no input file is given, the
standard input is assumed.
-new This option forces creation of a new colormap for displaying
the image. If the image characteristics happen to match those
of the display, this can get the image on the screen faster,
but at the cost of using a new colormap (which on most displays
will cause other windows to go technicolor).
-noclick
Clicking any button in the window will terminate the
application, unless this option is specified. Termination can
always be achieved by typing 'q', 'Q', or ctrl-c.
-plane number
You can select a single bit plane of the image to display with
this option. Planes are numbered with zero being the least
significant bit.
-raw This option forces the image to be displayed with whatever
color values happen to currently exist on the screen. This
option is mostly useful when undumping an image back onto the
same screen that the image originally came from, while the
original windows are still on the screen, and results in
getting the image on the screen faster.
-rv If a bitmap image (or a single plane of an image) is displayed,
this option forces the foreground and background colors to be
swapped. This may be needed when displaying a bitmap image
which has the color sense of pixel values "0" and "1" reversed
from what they are on your display.
-scale Allow the window to be resized, and scale the image to the size
of the window.
-std maptype
This option causes the image to be displayed using the
specified Standard Colormap. The property name is obtained by
converting the type to upper case, prepending "RGB_", and
appending "_MAP". Typical types are "best", "default", and
"gray". See xstdcmap(1) for one way of creating Standard
Colormaps.
-vis vis-type-or-id
This option allows you to specify a particular visual or visual
class. The default is to pick the "best" one. A particular
class can be specified: "StaticGray", "GrayScale",
"StaticColor", "PseudoColor", "DirectColor", or "TrueColor".
Or "Match" can be specified, meaning use the same class as the
source image. Alternatively, an exact visual id (specific to
the server) can be specified, either as a hexadecimal number
(prefixed with "0x") or as a decimal number. Finally,
"default" can be specified, meaning to use the same class as
the colormap of the root window. Case is not significant in
any of these strings.
ENVIRONMENT
DISPLAY To get default display.
FILES
XWDFile.h
X Window Dump File format definition file.
BUGS
xwud doesn't handle big/deep images very well on servers that don't
have the BIG-REQUESTS extension.
