animate – animate a sequence of images
USAGE
animate [ options ...] file [ [ options ...] file ...]
DESCRIPTION
Animate displays a sequence of images on any workstation display run-
ning 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 continu-
ous-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 back-
drop, use:
animate +borderwidth -backdrop cockatoo.*

For a more detailed description of each option, see Options,
above. 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 ani-
mate three images, the first with 32 colors, the second with an
unlimited number of colors, and the third with only 16 colors,
use:
animate -colors 32 cockatoo.1 -noop cockatoo.2
-colors 16 cockatoo.3
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.
MOUSE BUTTONS
Press any button to map or unmap the Command widget. See the next sec-
tion for more information about the Command widget.

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 (class Background)
.in 20
Specifies the preferred color to use for the Image window
background. The default is #ccc.
borderColor (class BorderColor)
.in 20
Specifies the preferred color to use for the Image window
border. The default is #ccc.
borderWidth (class BorderWidth)
.in 20
Specifies the width in pixels of the Image window border.
The default is 2.
font (class Font or FontList)
.in 20
Specifies the name of the preferred font to use in normal
formatted text. The default is 14 point Helvetica.
foreground (class Foreground)
.in 20
Specifies the preferred color to use for text within the
Image window. The default is black.
geometry (class geometry)
.in 20
Specifies the preferred size and position of the image
window. It is not necessarily obeyed by all window man-
agers. 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 (class IconGeometry)
.in 20
Specifies the preferred size and position of the applica-
tion 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 (class Iconic)
.in 20
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 man-
agers may choose not to honor the application’s request.
matteColor (class MatteColor)
.in 20
Specify the color of windows. It is used for the back-
grounds of windows, menus, and notices. A 3D effect is
achieved by using highlight and shadow colors derived from
this color. Default value: #ddd.
name (class Name)
.in 20
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 (class SharedMemory)
.in 20
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 (class textFont)
.in 20
Specifies the name of the preferred font to use in fixed
(typewriter style) formatted text. The default is 14 point
Courier.
title (class Title)
.in 20
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 con-
figuration files in $HOME/.magick if the directory exists. See
MAGICK_CODER_MODULE_PATH, MAGICK_CONFIGURE_PATH, and MAGICK_FIL-
TER_MODULE_PATH if more flexibility is needed.
MAGICK_CODER_MODULE_PATH
Search path to use when searching for image format coder mod-
ules. 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 Win-
dows). 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 operat-
ing 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 applica-
tions should write temporary files. Overridden by MAGICK_TMPDIR
if it is set.
CONFIGURATION FILES

colors.mgk
colors configuration file
delegates.mgk
delegates configuration file
log.mgk
logging configuration file
