XWD2STIFF(1) Impressario XWD2STIFF(1)NAMExwd2stiff - convert an X Window Dump (XWD) image file to Stream TIFF
(STIFF)
SYNOPSISxwd2stiff [-O filename] [-L filename]
[-c] [-h] [-D] [XWDFilename ...]
DESCRIPTIONxwd2stiff converts X Window Dump image files into Stream TIFF (STIFF)
format.
By default, xwd2stiff reads its input image from the standard input,
writes its output to the standard output and sends messages to standard
error. If one or more image files are specified on the command line,
xwd2stiff reads input from these files rather than the standard input.
-O filename
Specifies the name of the file to which the STIFF output will
be sent. If the -O option is not specified, output will be
sent to the standard output.
-L filename
Specifies the name of the file to which error, warning and
informational messages are to be written. If the file specified
already exists, any messages generated by xwd2stiff will be
appended to the end of the file. If the -L option is not
specified, message output will be sent to standard error.
-c XWD images created under a DirectColor visual often have an
incorrect colormap stored in the image. Typically the image
data itself is correct and can be converted properly without
reference to the colormap. By default, xwd2stiff does not
reference the colormap when converting an XWD image created
with a DirectColor visual. Specifying the -c option forces
xwd2stiff to use the colormap stored in the image when
converting a DirectColor image. The -c option effects the use
of the colormap only for DirectColor images.
-h Prints a program usage message to the standard error. This
usage message also lists the currently supported output
configurations.
-D Specifies verbose output for debugging purposes.
NOTES
1. xwd2stiff supports conversion of X11 XWD format files. X10 XWD files
are not supported.
2. xwd2stiff supports conversion of a wide variety of XWD images. The
program supports images saved under the StaticGray, GrayScale,
StaticColor, PseudoColor, TrueColor and DirectColor visuals. Images

may be 1, 2, 4, 8, 12 or 24 bits deep and may be in either MSBFirst
or LSBFIrst byte and bit order. The image may be in XYBitmap,
XYPixmap or ZPixmap format.
3. Images stored under the GrayScale, StaticColor or PseudoColor visual
must contain a colormap. If the colormap is not present, the image
will not be converted. DirectColor images must contain a colormap
only if the -c option is specified. If a StaticGray image does not
contain a colormap, a linear gray ramp will be used.
4. Due to processing overhead within Xlib, the conversion of images in
the XYPixmap format is slow in comparison to the other formats. This
is caused by the manner in which X organizes the image data. The
XYPixmap format should be avoided in favor of the ZPixmap format.
5. If xwd2stiff is given an unrecognized or incomplete command line
option switch, it will print a warning message to the standard
error, ignore the option and continue processing.
