DESCRIPTION

14       Xwud  is  an  X  Window  System image undumping utility.  Xwud allows X
15       users to display in a window an image saved in  a  specially  formatted
16       dump file, such as produced by xwd(1).

OPTIONS

19       -bg color
20               If a bitmap image (or a single plane of an image) is displayed,
21               this option can be used to specify the color to display for the
22               "0" bits in the image.
23
24       -display display
25               This option allows you to specify the server to connect to; see
26               X(7).
27
28       -dumpheader
29               This option prints out the XWD header information only.   Noth‐
30               ing is displayed.
31
32       -fg color
33               If a bitmap image (or a single plane of an image) is displayed,
34               this option can be used to specify the color to display for the
35               "1" bits in the image.
36
37       -geometry geom
38               This  option allows you to specify the size and position of the
39               window.  Typically you will only want to specify the  position,
40               and let the size default to the actual size of the image.
41
42       -help   Print out a short description of the allowable options.
43
44       -in file
45               This  option  allows  the  user to explicitly specify the input
46               file on the command line.  If no input file is given, the stan‐
47               dard input is assumed.
48
49       -new    This  option  forces  creation of a new colormap for displaying
50               the image.  If the image characteristics happen to match  those
51               of  the  display,  this can get the image on the screen faster,
52               but at the cost of using a new colormap (which on most displays
53               will cause other windows to go technicolor).
54
55       -noclick
56               Clicking  any  button in the window will terminate the applica‐
57               tion, unless this option is specified.  Termination can  always
58               be achieved by typing 'q', 'Q', or ctrl-c.
59
60       -plane number
61               You  can select a single bit plane of the image to display with
62               this option.  Planes are numbered with  zero  being  the  least
63               significant bit.
64
65       -raw    This  option  forces  the  image  to be displayed with whatever
66               color values happen to currently exist on the screen.  This op‐
67               tion  is  mostly  useful  when undumping an image back onto the
68               same screen that the image  originally  came  from,  while  the
69               original  windows  are still on the screen, and results in get‐
70               ting the image on the screen faster.
71
72       -rv     If a bitmap image (or a single plane of an image) is displayed,
73               this  option  forces the foreground and background colors to be
74               swapped.  This may be needed when  displaying  a  bitmap  image
75               which  has the color sense of pixel values "0" and "1" reversed
76               from what they are on your display.
77
78       -scale  Allow the window to be resized, and scale the image to the size
79               of the window.
80
81       -std maptype
82               This  option  causes the image to be displayed using the speci‐
83               fied Standard Colormap.  The property name is obtained by  con‐
84               verting  the type to upper case, prepending "RGB_", and append‐
85               ing "_MAP".  Typical types are "best", "default",  and  "gray".
86               See xstdcmap(1) for one way of creating Standard Colormaps.
87
88       -version
89               This  option  causes  xwd  to print its version information and
90               exit.
91
92       -vis vis-type-or-id
93               This option allows you to specify a particular visual or visual
94               class.   The  default  is to pick the "best" one.  A particular
95               class can be  specified:  "StaticGray",  "GrayScale",  "Static‐
96               Color",   "PseudoColor",  "DirectColor",  or  "TrueColor".   Or
97               "Match" can be specified, meaning use the  same  class  as  the
98               source  image.   Alternatively, an exact visual id (specific to
99               the server) can be specified, either as  a  hexadecimal  number
100               (prefixed  with  "0x")  or  as a decimal number.  Finally, "de‐
101               fault" can be specified, meaning to use the same class  as  the
102               colormap of the root window.  Case is not significant in any of
103               these strings.

BUGS

113       xwud doesn't handle big/deep images very well  on  servers  that  don't
114       have the BIG-REQUESTS extension.
