- <h2>ANIMATION TOOL (gis.m)</h2>
- The Animation Tool is an interactive interface to display a series of
- raster maps as an animation. Rasters can be added individually or as a
- prefix followed by a sequential number suffix.
- <br>
- <h3>Using the Animation Tool</h3>
- The Animation Tool is started from the <i>File</i> menu or
- from the animation button (<img src="icons/grass/module-xganim.gif" alt="icon">)
- on the GIS Manager toolbar.
- <P>
- The main animation window has a toolbar for selecting maps to display
- and controling the animation, and a display area. The display area can
- show a single, full-screen animation, or two to four simultaneous
- quarter-screen animations.
- <br><br><br>

- <h3>Selecting Maps to Animate</h3>
- Click the maps button (<img src="icons/grass/element-cell.gif" alt="icon">)
- on the main animation window toolbar to open a map selection window.
- <br><br>
- <div align="center">
- <img src="gm_animate1.png" alt="Animation map selection window" height="206" width="446">
- </div>
- <br>
- A map or map series must be entered in the entry for frame 1. If a map
- series is only entered for frame 1, a single, full-frame animation will be
- displayed. If map series are entered for other frames, two to four
- quarter-frame animations will be displayed (see example image above).
- Raster maps can be added individually or as a prefix followed by a sequential
- number suffix. <br><ul><li>To enter maps individually, enter
- each map name separated by a comma (no space) from the previous map
- name (see the entry for frame 3 in the example image above).</li>
- <li>For a map series entered in the prefix/suffix format, the suffix can be
- specified as a range of numbers in side parentheses. In the example image
- above, "map(1-4)" will specified raster maps map1 through map4. </li>
- <li>
- The suffix for a map series also can be specified using Unix-style wildcard
- matching. In the examle above "rdbuffer[0-1][1-9]" specifies raster
- maps rdbuffer01 through rdbuffer19.</li><li>Multiple specification
- forms can be mixed on a single entry line. For example, you could specify
- "rast-a,rast-b,rast-(1-50),rast[0-9][0-9]". This will specify rast-a,
- rast-b, rast-1 through rast-50, and rast00 through rast99.
- <br>
- </li>
- </ul>
- <h3>Controlling the Animation</h3>
- The animation can be controlled in various ways by using the buttons on the
- main animation window toobar.
- <P>
- <img src="gm_animatetool.png" alt="Animation Toolbar">
- <P>
- <img src="icons/grass/gui-rewind.gif">
- The rewind button will set the display to the first animation frame.
- <P>
- <img src="icons/grass/gui-rplay.gif">
- The reverse button will play the animation in reverse order.
- <P>
- <img src="icons/grass/gui-stepb.gif"> The reverse step button will step
- through the animation frame by frame in reverse order.
- <P>
- <img src="icons/grass/gui-stop.gif"> The pause button will stop the
- animation at whatever frame is visible when the animation is stopped.
- The animation will be continued from this frame when a forward or reverse
- button is pressed.
- <P>
- <img src="icons/grass/gui-stepf.gif"> The forward step button will step
- through the animation frame by frame.
- <P>
- <img src="icons/grass/gui-play.gif"> The play button will display the maps
- of the animation in the order they are listed in the map selection window.
- <P>
- <img src="icons/grass/gui-snail.gif"> The slow button will increase the
- time between the display of each consecutive frame in the animation,
- causing it to to slow down.
- <P>
- <img src="icons/grass/gui-rabbit.gif"> The fast button will decrease the
- time between the display of each consecutive frame in the animation,
- causing it to to speed up.
- <P>
- <img src="icons/grass/gui-loop.gif"> The repeat switch will cause the
- animation to repeatedly cycle from first to last frame if the play button
- is pressed, or cycle from last to first if the reverse button is pressed.
- <P>
- <img src="icons/grass/gui-swing.gif"> The alternating switch will cause the
- animation to alternately play from first frame to last frame, and from last
- to first.
- <P>
- <tt>[Names]</tt> The names switch will cause the file names of the maps used for the
- animation to display in the lower left corner of each animation frame.
- <P>
- <img src="icons/grass/gui-exit.gif"> The Exit button will quit the Animation Tool.
