Animate displays a sequence of images on any workstation display
running an X server. animate first determines the hardware capabilities
of the workstation. If the number of unique colors in an 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 sequence can display on a continuous-tone 24 bits-per-pixel
device.
To help prevent color flashing on X server visuals that have colormaps,
animate
creates a single colormap from the image sequence. This can be rather time
consuming. You can speed this operation up by reducing the colors in the
image before you "animate" them. Use mogrify to color reduce the
images to a single colormap. See mogrify(1) for details. Alternatively,
you can use a Standard Colormap; or a static, direct, or true color visual.
You can define a Standard Colormap with xstdcmap. See xstdcmap(1)
for details. This method is recommended for colormapped X server because
it eliminates the need to compute a global colormap.
EXAMPLES
To animate a set of images of a cockatoo, use:
animate cockatoo.*
To animate a cockatoo image sequence while using the Standard Colormap
best, use:
xstdcmap -best
animate -map best cockatoo.*
To animate an image of a cockatoo without a border centered on a backdrop,
use:
animate +borderwidth -backdrop cockatoo.*

ImageMagick(1).
Any option you specify on the command line remains in effect for the group
of images following it, until the group is terminated by the appearance of
any option or -noop. For example, to animate three images, the first
with 32 colors, the second with an unlimited number of colors, and the
third with only 16 colors, use:
Animate options can appear on the command line or in your X resources
file. See X(1). Options on the command line supersede values specified
in your X resources file.
Image filenames may appear in any order on the command line if the image
format is MIFF (refer to miff(5) and the
scene keyword
is specified in the image. Otherwise the images will display in the order
they appear on the command line.

X RESOURCES
Animate options can appear on the command line or in your X resource
file. Options on the command line supersede values specified in your X
resource file. See X(1) for more information on X resources.
All animate options have a corresponding X resource. In addition,
the animate program uses the following X resources:
background(classBackground)
Specifies the preferred color to use for the Image window background. The
default is #ccc.
borderColor(classBorderColor)
Specifies the preferred color to use for the Image window border. The default
is #ccc.
borderWidth(classBorderWidth)
Specifies the width in pixels of the Image window border. The default is
2.
font(classFontorFontList)
Specifies the name of the preferred font to use in normal formatted text.
The default is 14 point Helvetica.
foreground(classForeground)
Specifies the preferred color to use for text within the Image window.
The default is black.
geometry(classgeometry)
Specifies the preferred size and position of the image window. It is not
necessarily obeyed by all window managers.
Offsets, if present, are handled in X(1) style. A negative x offset is
measured from the right edge of the screen to the right edge of the icon,
and a negative y offset is measured from the bottom edge of the screen
to the bottom edge of the icon.
iconGeometry(classIconGeometry)
Specifies the preferred size and position of the application when iconified.
It is not necessarily obeyed by all window managers.
Offsets, if present, are handled in the same manner as in class Geometry.
iconic(classIconic)
This resource indicates that you would prefer that the application's windows
initially not be visible as if the windows had be immediately iconified
by you. Window managers may choose not to honor the application's request.
matteColor(classMatteColor)
Specify the color of windows. It is used for the backgrounds of windows,
menus, and notices. A 3D effect is achieved by using highlight and shadow
colors derived from this color. Default value: #ddd.
name(className)
This resource specifies the name under which resources for the application
should be found. This resource is useful in shell aliases to distinguish
between invocations of an application, without resorting to creating links
to alter the executable file name. The default is the application name.
sharedMemory(classSharedMemory)
This resource specifies whether animate should attempt use shared memory
for pixmaps. ImageMagick must be compiled with shared memory support, and
the display must support the MIT-SHM extension. Otherwise, this resource
is ignored. The default is True.
text_font(classtextFont)
Specifies the name of the preferred font to use in fixed (typewriter style)
formatted text. The default is 14 point Courier.
title(classTitle)
This resource specifies the title to be used for the Image window. This
information is sometimes used by a window manager to provide some sort
of header identifying the window. The default is the image file name.
ENVIRONMENT
COLUMNS
Output screen width. Used when formatting text for the screen. Many
Unix systems keep this shell variable up to date, but it may need to be
explicitly exported in order for ImageMagick to see it.
DISPLAY
X11 display ID (host, display number, and screen in the form
hostname:display.screen).
HOME
Location of user's home directory. ImageMagick searches for
configuration files in $HOME/.magick if the directory exists. See
MAGICK_CODER_MODULE_PATH, MAGICK_CONFIGURE_PATH, and
MAGICK_FILTER_MODULE_PATH if more flexibility is needed.
MAGICK_CODER_MODULE_PATH
Search path to use when searching for image format coder modules.
This path allows the user to arbitrarily extend the image formats
supported by ImageMagick by adding loadable modules to an arbitrary
location rather than copying them into the ImageMagick installation
directory. The formatting of the search path is similar to operating
system search paths (i.e. colon delimited for Unix, and semi-colon
delimited for Microsoft Windows). This user specified search path is used
before trying the default search path.
MAGICK_CONFIGURE_PATH
Search path to use when searching for configuration (.mgk) files.
The formatting of the search path is similar to operating system search
paths (i.e. colon delimited for Unix, and semi-colon delimited for
Microsoft Windows). This user specified search path is used before trying
the default search path.
MAGICK_DEBUG
Debug options (see -debug for details)
MAGICK_FILTER_MODULE_PATH
Search path to use when searching for filter process modules
(invoked via -process). This path allows the user to arbitrarily
extend ImageMagick's image processing functionality by adding loadable
modules to an arbitrary location rather than copying them into the
ImageMagick installation directory. The formatting of the search path
is similar to operating system search paths (i.e. colon delimited for
Unix, and semi-colon delimited for Microsoft Windows). This user
specified search path is used before trying the default search path.
MAGICK_FONT_PATH
Directory where ImageMagick should look for TrueType and
Postscript Type1 font files if the font file is not found in the current
directory. It is preferred to define the available fonts via type.mgk
rather than use MAGICK_FONT_PATH.
MAGICK_HOME
Path to top of ImageMagick installation directory. Only observed
by "uninstalled" builds of ImageMagick which do not have their location
hard-coded or set by an installer.
MAGICK_DISK_LIMIT
Maximum amount of disk space allowed for use by the pixel cache.
MAGICK_FILES_LIMIT
Maximum number of open files.
MAGICK_MAP_LIMIT
Maximum size of a memory map.
MAGICK_MEMORY_LIMIT
Maximum amount of memory to allocate from the heap.
MAGICK_TMPDIR
Path to directory where ImageMagick should write temporary
files. The default is to use the system default, or the location set by
TMPDIR.
TMPDIR
For POSIX-compatible systems (Unix-compatible), the path to the
directory where all applications should write temporary files.
Overridden by MAGICK_TMPDIR if it is set.
TMP or TEMP
For Microsoft Windows, the path to the directory where applications
should write temporary files. Overridden by MAGICK_TMPDIR if it
is set.
CONFIGURATION FILES
ImageMagick uses a number of XML format configuration files:
The MIT X Consortium for making network transparent graphics a
reality.
Michael Halle, Spatial Imaging Group at MIT, for the initial
implementation of Alan Paeth's image rotation algorithm.
David Pensak, duPont, for providing a computing
environment that made this program possible.
Paul Raveling, USC Information Sciences Institute.
The spatial subdivision color reduction algorithm is based on his Img
software.
