see \fIX(1)\fP. +.PP +.TP 8 +.B "-fg \fIcolor\fP" +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. +.PP +.TP 8 +.B "-geometry \fIgeom\fP" +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. +.PP +.TP 8 +.B "-help" +Print out a short description of the allowable options. +.PP +.TP 8 +.B "-in \fIfile\fP" +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. +.PP +.TP 8 +.B -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). +.PP +.TP 8 +.B "-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. +.PP +.TP 8 +.B "-plane \fInumber\fP" +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. This option can be used to figure out which plane to +pass to \fIxpr(1)\fP for printing. +.PP +.TP 8 +.B -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. +.PP +.TP 8 +.B -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. +.PP +.TP 8 +.B -scale +Allow the window to be resized, and scale the image to the size of the window. +.PP +.TP 8 +.B "-std \fImaptype\fP" +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 \fIxstdcmap(1)\fP +for one way of creating Standard Colormaps. +.PP +.TP 8 +.B "-vis \fIvis-type-or-id\fP" +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. +.SH ENVIRONMENT +.PP +.TP 8 +.B DISPLAY +To get default display. +.SH FILES +.PP +.TP 8 +.B XWDFile.h +X Window Dump File format definition file. +.SH BUGS +xwud doesn't handle big/deep images very well on servers that don't +have the BIG-REQUESTS extension. +.SH SEE ALSO +xwd(1), xpr(1), xstdcmap(1), X(1) +.SH AUTHOR +Bob Scheifler, MIT X Consortium + + |
