tiffgt  -  display  an  image  stored  in a TIFF file (Silicon Graphics


   tiffgt [ options ] input.tif ...


   tiffgt displays one or more images stored  using  the  Tag  Image  File
   Format, Revision 6.0.  Each image is placed in a fixed size window that
   the user must position on  the  display  (unless  configured  otherwise
   through X defaults).  If the display has fewer than 24 bitplanes, or if
   the image does not warrant full color, then RGB color values are mapped
   to  the  closest  values that exist in the colormap (this is done using
   the rgbi routine found in the graphics utility library -lgutil.)

   tiffgt  correctly   handles   files   with   any   of   the   following
        BitsPerSample              1, 2, 4, 8, 16
        SamplesPerPixel            1, 3, 4 (the 4th sample is ignored)
        PhotometricInterpretation  0 (min-is-white), 1 (min-is-black), 2 (RGB), 3 (palette), 6 (YCbCr)
        PlanarConfiguration        1 (contiguous), 2 (separate)
        Orientation                1 (top-left), 4 (bottom-left)
   Data may be organized as strips or tiles and may be compressed with any
   of the compression algorithms supported by the libtiff(3) library.

   For palette images (PhotometricInterpretation=3), tiffgt  inspects  the
   colormap  values and assumes either 16-bit or 8-bit values according to
   the maximum value.  That is, if no colormap entry greater than  255  is
   found,  tiffgt assumes the colormap has only 8-bit values; otherwise it
   assumes 16-bit values.  This inspection is done to  handle  old  images
   written by previous (incorrect) versions of libtiff.

   tiffgt  can be used to display multiple images one-at-a-time.  The left
   mouse button switches the display to the first image in the  next  file
   in  the  list  of files specified on the command line.  The right mouse
   button switches to the first image in the previous file  in  the  list.
   The  middle  mouse  button  causes  the  first  image in the first file
   specified on the  command  line  to  be  displayed.   In  addition  the
   following keyboard commands are recognized:

   b      Use  a PhotometricInterpretation of MinIsBlack in displaying the
          current image.

   l      Use a FillOrder of lsb-to-msb in decoding the current image.

   m      Use a FillOrder of msb-to-lsb in decoding the current image.

   c      Use a colormap visual to display the current image.

   r      Use a true color (24-bit RGB)  visual  to  display  the  current

   w      Use  a PhotometricInterpretation of MinIsWhite in displaying the
          current image.

   W      Toggle (enable/disable) display of  warning  messages  from  the
          TIFF library when decoding images.

   E      Toggle  (enable/disable) display of error messages from the TIFF
          library when decoding images.

   z      Reset all  parameters  to  their  default  settings  (FillOrder,
          PhotometricInterpretation, handling of warnings and errors).

   PageUp Display the previous image in the current file or the last image
          in the previous file.

          Display the next image in the current file or the first image in
          the next file.

   Home   Display the first image in the current file.

   End    Display the last image in the current file (unimplemented).


   -c     Force image display in a colormap window.

   -d     Specify an image to display by directory number.  By default the
          first image in the file is displayed.  Directories are  numbered
          starting at zero.

   -e     Enable  reporting  of  error messages from the TIFF library.  By
          default tiffgt silently ignores images that cannot be read.

   -f     Force tiffgt to run as a foreground process.  By default  tiffgt
          will  place  itself  in  the  background  once it has opened the
          requested image file.

   -l     Force the presumed bit ordering to be LSB to MSB.

   -m     Force the presumed bit ordering to be MSB to LSB.

   -o     Specify an image to display by directory offset.  By default the
          first  image  in the file is displayed.  Directories offsets may
          be specified using C-style syntax; i.e.  a  leading  ``0x''  for
          hexadecimal and a leading ``0'' for octal.

   -p     Override  the  value  of  the PhotometricInterpretation tag; the
          parameter may be one of: miniswhite, minisblack,  rgb,  palette,
          mask, separated, ycbcr, and cielab.

   -r     Force image display in a full color window.

   -s     Stop  on  the  first  read  error.  By default all errors in the
          input data are ignored and tiffgt does it's best to  display  as
          much of an image as possible.

   -w     Enable  reporting of warning messages from the TIFF library.  By
          default tiffgt ignores warning messages generated  when  reading
          an image.

   -v     Place  information  in  the  title  bar  describing what type of
          window (full color or colormap) is being used, the name  of  the
          input  file, and the directory index of the image (if non-zero).
          By default, the window type is not shown in the title bar.


   Images wider and taller than the  display  are  silently  truncated  to
   avoid crashing old versions of the window manager.
