NAME
tiffgt - display an image stored in a
TIFF
file (Silicon Graphics version)
SYNOPSIS
tiffgt
[
options
]
input.tif ...
DESCRIPTION
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 characteristics:
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 (PhotomatricInterpretation=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
PhotometricIntepretation
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-tolmsb 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 image.
w
Use a
PhotometricIntepretation
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.
PageDown
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).
OPTIONS
-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.
BUGS
Images wider and taller than the display are silently truncated to avoid
crashing old versions of the window manager.
