.SH NAME
display - display an image on any workstation running X
.SH SYNOPSIS
.B "display" [ \fIoptions\fP ...] \fIfile\fP
[ [ \fIoptions\fP ...] \fIfile\fP ...]
.SH DESCRIPTION
\fIDisplay\fP is a machine architecture independent image processing
and display program.  It can display an image on any workstation
display running an X server.  \fIDisplay\fP first determines the
hardware capabilities of the workstation.  If the number of unique
colors in the image is less than or equal to the number the workstation
can support, the image is displayed in an X window.  Otherwise the
number of colors in the image is first reduced to match the color
resolution of the workstation before it is displayed.

This means that a continuous-tone 24 bits-per-pixel image can display on a
8 bit pseudo-color device or monochrome device.  In most instances the
reduced color image closely resembles the original.  Alternatively, a
monochrome or pseudo-color image can display on a continuous-tone 24
bits-per-pixel device.
.SH EXAMPLES
To scale an image of a cockatoo to exactly 640 pixels in width and 480
pixels in height and position the window at location (200,200), use:
.PP
X     display -geometry 640x480\+200\+200 cockatoo.miff
.PP
To display an image of a cockatoo without a border centered on a
backdrop, use:
.PP
X     display +borderwidth -backdrop cockatoo.miff
.PP
To tile an image of a cockatoo onto the root window, use:
.PP
X     display -window root cockatoo.miff
.SH OPTIONS
.TP 5
.B "-backdrop"
display the image centered on a backdrop.
X
This backdrop covers the entire workstation screen and is useful for
hiding other X window activity while viewing the image.   The color of
the backdrop is specified as the background color.  Refer to \fBX
RESOURCES\fP for details.
.TP 5
.B "-clip \fI<width>x<height>{\+-}<x offset>{\+-}<y offset>\fP"
preferred size and location of the clipped image.  See \fBX(1)\fP for details
about the geometry specification.
X
Use clipping to apply image processing options to, or display, a
particular area of an image.
X
The equivalent X resource for this option is \fBclipGeometry\fP
(class \fBClipGeometry\fP).  See \fBX RESOURCES\fP for details.
.TP 5
.B "-colormap \fItype\fP"
the type of colormap: \fIShared\fP or \fIPrivate\fP.
X
This option only applies when the default X server visual is
\fIPseudoColor\fP or \fIGrayScale\fP.  Refer to \fB-visual\fP for more
details.  By default, a shared colormap is allocated.  The image shares
colors with other X clients.  Some image colors could be approximated,
therefore your image may look very different than intended.  Choose
\fIPrivate\fP and the image colors appear exactly as they are
defined.  However, other clients may go "technicolor" when the image
colormap is installed.
.TP 5
.B "-colors \fIvalue\fP"
preferred number of colors in the image.
X
The actual number of colors in the image may be less than your request,
but never more.  Note, this is a color reduction option.  Images with
less unique colors than specified with this option will remain unchanged.
Refer to \fBQuantize(9)\fP for more details.
X
Note, options \fB-dither\fP, \fB-colorspace\fP, and \fB-treedepth\fP affect
the color reduction algorithm.
.TP 5
.B "-colorspace \fIvalue\fP"
the type of colorspace: \fIGRAY\fP, \fIRGB\fP, \fIXYZ\fP, \fIYIQ\fP, or
\fIYUV\fP.
X
Color reduction, by default, takes place in the RGB color space.
Empirical evidence suggests that distances in color spaces such as YUV
or YIQ correspond to perceptual color differences more closely
than do distances in RGB space.  These color spaces may give better
results when color reducing an image.  Refer to \fBQuantize(9)\fP for
more details.
X
The \fB-colors\fP or \fB-monochrome\fP option is required for this option
to take effect.
.TP 5
.B "-compress \fItype\fP"
the type of image compression: \fIQEncoded\fP or \fIRunlengthEncoded\fP.
X
Use this option with \fB-write\fP to specify the the type of image
compression.  See \fBMIFF(5)\fP for details.
X
Specify \fB\+compress\fP to store the binary image in an uncompressed format.
The default is the compression type of the specified image file.
.TP 5
.B "-delay \fIseconds\fP"
display the next image after pausing.
X
This option is useful when viewing several images in sequence.  Each
image will display and wait the number of seconds specified before the
next image is displayed.  The default is to display the image
and wait until you choose to display the next image or terminate the
program.
.TP 5
.B "-density \fI<width>x<height>
vertical and horizonal density of the image.
X
This option specifies an image density whose interpretation changes
with the type of image.  The default is 72 dots per inch in the
horizonal and vertical direction for Postscript.  Text files default to
80 characters in width and 60 lines in height.  Use this option to
alter the default density.
.TP 5
.B "-display \fIhost:display[.screen]\fP"
specifies the X server to contact; see \fBX(1)\fP.
.TP 5
.B "-dither"
apply Floyd/Steinberg error diffusion to the image.
X
The basic strategy of dithering is to trade intensity resolution for
spatial resolution by averaging the intensities of several neighboring
pixels.  Images which suffer from severe contouring when reducing colors
can be improved with this option.
X
The \fB-colors\fP or \fB-monochrome\fP option is required
for this option to take effect.
.TP 5
.B "-enhance"
apply a digital filter to enhance a noisy image.
.TP 5
.B "-gamma \fIvalue\fP"
level of gamma correction.
X
The same color image displayed on two different workstations may look
different due to differences in the display monitor.  Use gamma
correction to adjust for this color difference.  Reasonable values
extend from 0.8 to 2.3.
.TP 5
.B "-geometry \fI<width>x<height>{\+-}<x offset>{\+-}<y offset>\fP"
preferred size and location of the image window.  See \fBX(1)\fP for details
about the geometry specification.  By default, the window size is the image
size and the location is choosen by you when it is mapped.
X
If the specified image size is smaller than the actual image size, the
image is first reduced to an integral of the specified image size with
an antialias digital filter.  The image is then scaled to the exact
specified image size with pixel replication.  If the specified image
size is greater than the actual image size, the image is first enlarged
to an integral of the specified image size with bilinear
interpolation.  The image is then scaled to the exact specified image
size with pixel replication.
X
When displaying an image on an X server, \fI<x offset>\fP and
\fI<y offset>\fP is relative to the root window.  When printing an image,
\fI<x offset>\fP and \fI<y offset>\fP is relative to a Postscript
page.  See \fB-print\fP for more details.
X
The equivalent X resource for this option is \fBimageGeometry\fP
(class \fBImageGeometry\fP).  See \fBX RESOURCES\fP for details.
.TP 5
.B "-inverse"
apply color inversion to image.
X
The red, green, and blue intensities of an image are negated.
.TP 5
.B "-map \fItype\fP"
display image using this Standard Colormap type.
X
Choose from these Standard Colormap types:
X
X    default
X    best
X    red
X    green
X    blue
X    gray
X
The X server must support the Standard Colormap you choose, otherwise an
error occurs.  See \fBxstdcmap(1)\fP for one way of creating Standard
Colormaps.
.TP 5
.B "-monochrome"
transform the image to black and white.
X
Monochrome images can benefit from error diffusion.  Use \fB-dither\fP with
this option to diffuse the error.
.TP 5
.B "-noise"
reduce the noise in an image with a noise peak elimination filter.
X
The principal function of noise peak elimination filter is to smooth
the objects within an image without losing edge information and without
creating undesired structures.  The central idea of the algorithm is to
replace a pixel with its next neighbor in value within a 3 x 3 window,
if this pixel has been found to be noise.  A pixel is defined as noise
if and only if this pixel is a maximum or minimum within the 3 x 3 window.
.TP 5
.B "-normalize"
tranform image to span the full range of color values.  This is a contrast
enhancement technique.
.TP 5
.B "-print \fIfile\fP"
write image as encapsulated Postscript to a file.
X
If \fIfile\fP already exists, you will be prompted as to whether
it should be overwritten.
X
By default, the image is scaled and centered to fit on an 612x792 point
Postscript page.  To specify a specific image size or a particular location on
the Postscript page, use \fB-geometry\fP.
X
By default the image is output in portrait mode.  Use \fB-rotate 90\fP to
display the image in landscape mode.
X
You can view \fIfile\fP with any Postscript compatible viewer or
printer.  The image is displayed as color on viewers and printers that
support color Postscript, otherwise it is displayed as grayscale.
X
The equivalent X resource for this option is \fBprintFilename\fP
(class \fBPrintFilename\fP).  See \fBX RESOURCES\fP for details.
.TP 5
.B "-reflect"
create a "mirror image" by reflecting the image scanlines.
.TP 5
.B "-rotate \fIdegrees\fP"
apply Paeth image rotation to the image.
.TP 5
.B "-scale \fI<width factor>x<height factor>\fP"
preferred size factors of the image.
X
This option behaves like \fB-geometry\fP except the width and height values
are relative instead of absolute.  The image size is multiplied by the
width and height factors to obtain the final image dimensions.  If only
one factor is specified, both the width and height factors assume the
value.
X
Factors may be fractional.  For example, a factor of 1.5 will increase the
image size by one and one-half.
X
The equivalent X resource for this option is \fBscaleGeometry\fP
(class \fBScaleGeometry\fP).  See \fBX RESOURCES\fP for details.
.TP 5
.B "-scene \fIvalue\fP"
image scene number.
.TP 5
.B "-treedepth \fIvalue\fP"
Normally, this integer value is zero or one.  A zero or one tells
\fIdisplay\fP to choose a optimal tree depth for the color reduction
algorithm.
X
An optimal depth generally allows the best representation of the source
image with the fastest computational speed and the least amount of
memory.  However, the default depth is inappropriate for some images.
To assure the best representation, try values between 2 and 8 for this
parameter.  Refer to \fBQuantize(9)\fP for more details.
X
The \fB-colors\fP or \fB-monochrome\fP option is required
for this option to take effect.
.TP 5
.B -verbose
print detailed information about the image.
X
This information is printed: image scene number;  image name;  image
size; the image class (\fIDirectClass\fP or \fIPseudoClass\fP);  the total
number of unique colors;  and the number of seconds to read and
transform the image.  Refer to \fBMIFF(5)\fP for a description of
the image class.
X
If \fB-colors\fP is also specified, the total unique colors in the image
and color reduction error values are printed.  Refer to \fBQuantize(9)\fP
for a description of these values.
.TP 5
.B "-visual \fItype\fP"
display image using this visual type.
X
Choose from these visual classes:
X
X    StaticGray
X    GrayScale
X    StaticColor
X    PseudoColor
X    TrueColor
X    DirectColor
X    default
X    \fIvisual id\fP
X
The X server must support the visual you choose, otherwise an error occurs.
If a visual is not specified, the visual class that can display the most
simultaneous colors on the default X server screen is choosen.
.TP 5
.B "-window \fIid\fP"
set the background pixmap of this window to the image.
X
\fIid\fP can be a window id or name.  Specify \fBroot\fP to select X's root
window as the target window.
X
By default the image is tiled onto the background of the target
window.   If \fB-backdrop\fP or \fB-geometry\fP are specified, the
image is surrounded by the background color.  Refer to \fBX
RESOURCES\fP for details.
X
The image will not display on the root window if the image has more
unique colors than the target window colormap allows.  Use
\fB-colors\fP to reduce the number of colors.
.TP 5
.B "-write \fIfile\fP"
write image to a file.
X
If \fIfile\fP already exists, you will be prompted as to whether
it should be overwritten.
X
By default, the image is stored in the MIFF image format.  If the number of
unique colors in the image exceed 65535, it is stored as \fIDirectClass\fP;
otherwise, it is stored as \fIPseudoClass\fP format.  Refer to \fBMIFF(5)\fP
for more details.
X
By default, the image is written in the format that it was read in as.
To specify a particular image format, prefix \fIfile\fP with the image
type and a colon (i.e. mtv:image) or specify the image type as the
filename suffix (i.e. image.mtv).  See \fBconvert(1)\fP for a list of
valid image formats.  If \fIfile\fP has the extension \fB.Z\fP, the
file size is reduced using Lempel-Ziv coding with \fBcompress\fP.  If
\fIfile\fP already exists, you will be prompted as to whether it should
be overwritten.
X
Use \fB-compress\fP to specify the type of image compression.
X
The equivalent X resource for this option is \fBwriteFilename\fP
(class \fBWriteFilename\fP).  See \fBX RESOURCES\fP for details.
.PP
In addition to those listed above, you can specify these standard X
resources as command line options:  \fB-background\fP,
\fB-bordercolor\fP, \fB-borderwidth\fP,  \fB-font\fP,
\fB-foreground\fP, \fB-iconGeometry\fP, \fB-iconic\fP, \fB-name\fP, or
\fB-title\fP.  See \fBX RESOURCES\fP for details.
.PP
Any option you specify on the command line remains in effect until it is
explicitly changed by specifying the option again with a different effect.
For example to display two images, the first with 32 colors, and the
second with only 16 colors, use:
.PP
X     display -colors 32 cockatoo.miff -colors 16 macaw.miff
.PP
Change \fI-\fP to \fI\+\fP in any option above to reverse its effect.
For example, specify \fB\+compress\fP to store the binary image in an
uncompressed format.
.PP
\fIfile\fP specifies the image filename.  By default, the image format
is determined by its magic number. To specify a particular image format, precede
the filename with an image format name and a colon (i.e.
mtv:image) or specify the image type as the filename suffix (i.e. image.mtv).
See \fBconvert(1)\fP for a list of valid image formats.  Specify \fIfile\fP
as \fI-\fP for standard input or output.  If \fIfile\fP has the
extension \fB.Z\fP, the file is decoded with \fIuncompress\fP.

header identifying the window.  The default is the image file name.
.SH IMAGE PANNING
When an image exceeds the width or height of the X server screen,
\fIdisplay\fP maps a small panning window.  The rectangle within the
panning window shows the area that is currently displayed in the
the image window.  To "pan" about the image, press and drag the mouse
within the panning window.  The panning rectangle moves with the mouse
and the image window is updated to reflect the location of the
rectangle within the panning window.  When you have selected the area
of the image you wish to view, just release the mouse button.
X
The panning window goes away if the image becomes smaller than the
dimensions of the X server screen.
.SH IMAGE ANNOTATION
An image is annotated with text interactively.  There is no command
line argument to annotate an image.  To begin, press button 1 and

entered.  There is no way to `undo' your changes so be careful to
check your text before you press \fIESC\fP.
.PP
The actual color you request for the font is saved in the image.
However, the color that appears in your image window may be different.
For example, on a monochrome screen the text will appear black or white even
if you choose the color red as the font color.  However, the image saved to
a file with \fB-write\fP will be written with red lettering.  To assure
the correct color text in the final image, any \fIPseudoClass\fP image
is promoted to \fIDirectClass\fP (see \fBMIFF(5)\fP).  To
force a \fIPseudoClass\fP image to remain \fIPseudoClass\fP, use
\fB-colors\fP.
.SH IMAGE COMPOSITING
An image composite is created interactively.  There is no command line

X    minus
X    add
X    subtract
X    difference
X    replace
.PP
The operations behaves as follows:
.TP 9
.B over
The result will be the union of the two image shapes, with \fIimage\fP
obscuring \fIimage window\fP in the region of overlap.
.TP 9
.B in
The result is simply \fIimage\fP cut by the shape of \fIimage
window\fP.  None of the image data of \fIimage window\fP will be in the
result.
.TP 9
.B out
The resulting image is \fIimage\fP with the shape of \fIimage window\fP
cut out.
.TP 9
.B atop
The result is the same shape as image \fIimage window\fP, with
\fIimage\fP obscuring \fIimage window\fP where the image shapes
overlap.  Note this differs from \fBover\fP because the portion of
\fIimage\fP outside \fIimage window\fP's shape does not appear in the
result.
.TP 9
.B xor
The result is the image data from both \fIimage\fP and \fIimage window\fP
that is outside the overlap region.  The overlap region will be blank.
.TP 9
.B plus
The result is just the sum of the image data.  Output values are
clipped to 255 (no overflow).  This operation is independent
of the alpha channels.
.TP 9
.B minus
The result of \fIimage\fP \- \fIimage window\fP, with underflow clipped
to zero.  The alpha channel is ignored (set to 255, full coverage).
.TP 9
.B add
The result of \fIimage\fP + \fIimage window\fP, with overflow wrapping
around (\fImod\fP 256).
.TP 9
.B subtract
The result of \fIimage\fP - \fIimage window\fP, with underflow wrapping
around (\fImod\fP 256).  The \fBadd\fP and \fBsubtract\fP operators can
be used to perform reversible transformations.
.TP 9
.B difference
The result of abs(\fIimage\fP \- \fIimage window\fP).  This is useful
for comparing two very similar images.
.TP 9
.B replace
The resulting image is \fIimage window\fP replaced with \fIimage\fP.
Here the alpha information is ignored.
.PP
The image compositor requires an alpha, or matte channel in the image
for some operations.  This extra channel usually defines a mask which
represents a sort of a cookie-cutter for the image.  This is the case
when alpha is 255 (full coverage) for pixels inside the shape, zero
outside, and between zero and 255 on the boundary.  If \fIimage\fP does
not have an alpha channel, it is initialized with 0 for any pixel
matching in color to pixel location (0,0), otherwise 255.
.PP
Note that alpha information for \fIimage window\fP is not retained for
colormapped X server visuals (e.g. \fIStaticColor\fP,
\fIStaticColor\fP, \fIGrayScale\fP, \fIPseudoColor\fP).  Correct
compositing behavior may require a \fITrueColor\fP or \fIDirectColor\fP
visual or a \fIStandard Colormap\fP.
.PP
Choosing a composite operator is optional.  The default operator is
\Ifover\fP.  However, you must choose a location to composite your image
and press button 1.  Press and hold button 1 before releasing and an
outline of the image will appear to help you identify your location.
.PP
Immediately after releasing button 1, \fIimage window\fP is
permanently updated with your composited image.  There is no way to
`undo' your changes.  Be careful when choosing your location.
.PP
The actual colors of the composite image is saved.  However, the color
that appears in \fIimage window\fP may be different.  For example, on a
monochrome screen \fIimage window\fP will appear black or white even
though your composited image may have many colors.  If the image is
saved to a file it is written with the correct colors.  To assure the
correct colors are saved in the final image, any \fIPseudoClass\fP
image is promoted to \fIDirectClass\fP (see \fBMIFF(5)\fP).  To force a
\fIPseudoClass\fP image to remain \fIPseudoClass\fP, use \fB-colors\fP.

XXtp is a utility for retrieving, listing, or printing files from a
remote network site.  Xtp performs most of the same functions as the
ftp program, but does not require any interactive commands.  You simply
specify the file transfer task on the command line and xtp performs the
transfer automatically.
X
To retrieve file contrib/ImageMagick.tar.Z from host export.lcs.mit.edu,
use:
X
X  xtp -binary -retrieve ImageMagick.tar.Z export.lcs.mit.edu contrib
X
XXtp requires 4.3 BSD compatibilities.  I have successfully executed it on
a SUN, DEC Ultrix, MIPS, IBM RS/6000, and Ardent Titan.
