\section{NAME}
animate - animate a sequence of images

\section{Synopsis}

{\bf animate} {\bf [} {\it options\/} {\bf ...]} {\it file\/} [ [
{\it options\/} ...] {\it file\/} ...]


\section{Description}

{\bf Animate} displays a sequence of images on any workstation display
running an X server. {\bf 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,
{\bf 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 {\bf mogrify} to color reduce the
images to a single colormap. See {\bf 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 {\it xstdcmap\/}. See {\bf xstdcmap(1)}
for details. This method is recommended for colormapped X server because
it eliminates the need to compute a global colormap.


\section{Examples}

To animate a set of images of a cockatoo, use:

\begin{verbatim}
    animate cockatoo.*
\end{verbatim}

To animate a cockatoo image sequence while using the Standard Colormap
{\it best\/}, use:

\begin{verbatim}
    xstdcmap -best
    animate -map best cockatoo.*
\end{verbatim}

To animate an image of a cockatoo without a border centered on a backdrop,
use:

\begin{verbatim}
    animate +borderwidth -backdrop cockatoo.*
\end{verbatim}

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 {\bf -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:

\begin{verbatim}
     animate -colors 32 cockatoo.1 -noop cockatoo.2
             -colors 16 cockatoo.3
\end{verbatim}

{\bf Animate} options can appear on the command line or in your X resources
file. See {\it 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 {\it MIFF\/} (refer to {\bf miff(5)} and the
{\bf scene} keyword
is specified in the image. Otherwise the images will display in the order
they appear on the command line.


\section{Mouse Buttons}

Press any button to map or unmap the Command widget. See the next section
for more information about the Command widget.


\section{Command Widget}

The Command widget lists a number of sub-menus and commands. They are

Menu items with a indented triangle have a sub-menu. They are represented
above as the indented items. To access a sub-menu item, move the pointer
to the appropriate menu and press a button and drag. When you find the
desired sub-menu item, release the button and the command is executed.
Move the pointer away from the sub-menu if you decide not to execute a
particular command.

\end{description}


\section{X Resources}

{\bf 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 {\bf X(1)} for more information on X resources.

All {\bf animate} options have a corresponding X resource. In addition,
the {\bf animate} program uses the following X resources:
\begin{description}
\item{{\bf background} {\bf (}{\it class\/} {\bf Background)}}

Specifies the preferred color to use for the Image window background. The
default is \#ccc.
\item{{\bf borderColor} {\bf (}{\it class\/} {\bf BorderColor)}}

Specifies the preferred color to use for the Image window border. The default
is \#ccc.
\item{{\bf borderWidth} {\bf (}{\it class\/} {\bf BorderWidth)}}

Specifies the width in pixels of the Image window border. The default is
2.
\item{{\bf font} {\bf (}{\it class\/} {\bf Font} {\bf or} {\bf FontList)}}

Specifies the name of the preferred font to use in normal formatted text.
The default is 14 point {\it Helvetica\/}.
\item{{\bf foreground} {\bf (}{\it class\/} {\bf Foreground)}}

Specifies the preferred color to use for text within the Image window.
The default is black.
\item{{\bf geometry} {\bf (}{\it class\/} {\bf geometry)}}

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 {\it 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.
\item{{\bf iconGeometry} {\bf (}{\it class\/} {\bf IconGeometry)}}

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.
\item{{\bf iconic} {\bf (}{\it class\/} {\bf Iconic)}}

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.
\item{{\bf matteColor} {\bf (}{\it class\/} {\bf MatteColor)}}

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.
\item{{\bf name} {\bf (}{\it class\/} {\bf Name)}}

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.
\item{{\bf sharedMemory} {\bf (}{\it class\/} {\bf SharedMemory)}}

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.
\item{{\bf text\_font} {\bf (}{\it class\/} {\bf textFont)}}

Specifies the name of the preferred font to use in fixed (typewriter style)
formatted text. The default is 14 point {\it Courier\/}.
\item{{\bf title} {\bf (}{\it class\/} {\bf Title)}}

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.
