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

  28. <h3>Selecting Maps to Animate</h3>
  29. Click the maps button (<img src="icons/grass/element-cell.gif" alt="icon">)
  30. on the main animation window toolbar to open a map selection window.
  31. <br><br>
  32. <div align="center">

  34. </div>
  35. <br>
  36. A map or map series must be entered in the entry for frame 1. If a map
  37. series is only entered for frame 1, a single, full-frame animation will be
  38. displayed. If map series are entered for other frames, two to four
  39. quarter-frame animations will be displayed (see example image above).
  40. Raster maps can be added individually or as a prefix followed by a sequential
  41. number suffix. <br><ul><li>To enter maps individually, enter
  42. each map name separated by a comma (no space) from the previous map
  43. name (see the entry for frame 3 in the example image above).</li>
  44. <li>For a map series entered in the prefix/suffix format, the suffix can be
  45. specified as a range of numbers in side parentheses. In the example image
  46. above, "map(1-4)" will specified raster maps map1 through map4. </li>
  47. <li>
  48. The suffix for a map series also can be specified using Unix-style wildcard
  49. matching. In the examle above "rdbuffer[0-1][1-9]" specifies raster
  50. maps rdbuffer01 through rdbuffer19.</li><li>Multiple specification
  51. forms can be mixed on a single entry line. For example, you could specify
  52. "rast-a,rast-b,rast-(1-50),rast[0-9][0-9]". This will specify rast-a,
  53. rast-b, rast-1 through rast-50, and rast00 through rast99.
  54. <br>
  55. </li>
  56. </ul>
  57. <h3>Controlling the Animation</h3>
  58. The animation can be controlled in various ways by using the buttons on the
  59. main animation window toobar.

  63. <img src="icons/grass/gui-rewind.gif">
  64. The rewind button will set the display to the first animation frame.
  65. <P>
  66. <img src="icons/grass/gui-rplay.gif">
  67. The reverse button will play the animation in reverse order.
  68. <P>
  69. <img src="icons/grass/gui-stepb.gif"> The reverse step button will step
  70. through the animation frame by frame in reverse order.
  71. <P>
  72. <img src="icons/grass/gui-stop.gif"> The pause button will stop the
  73. animation at whatever frame is visible when the animation is stopped.
  74. The animation will be continued from this frame when a forward or reverse
  75. button is pressed.
  76. <P>
  77. <img src="icons/grass/gui-stepf.gif"> The forward step button will step
  78. through the animation frame by frame.
  79. <P>
  80. <img src="icons/grass/gui-play.gif"> The play button will display the maps
  81. of the animation in the order they are listed in the map selection window.
  82. <P>
  83. <img src="icons/grass/gui-snail.gif"> The slow button will increase the
  84. time between the display of each consecutive frame in the animation,
  85. causing it to to slow down.
  86. <P>
  87. <img src="icons/grass/gui-rabbit.gif"> The fast button will decrease the
  88. time between the display of each consecutive frame in the animation,
  89. causing it to to speed up.
  90. <P>
  91. <img src="icons/grass/gui-loop.gif"> The repeat switch will cause the
  92. animation to repeatedly cycle from first to last frame if the play button
  93. is pressed, or cycle from last to first if the reverse button is pressed.
  94. <P>
  95. <img src="icons/grass/gui-swing.gif"> The alternating switch will cause the
  96. animation to alternately play from first frame to last frame, and from last
  97. to first.
  98. <P>
  99. <tt>[Names]</tt> The names switch will cause the file names of the maps used for the
  100. animation to display in the lower left corner of each animation frame.
  101. <P>
  102. <img src="icons/grass/gui-exit.gif"> The Exit button will quit the Animation Tool.
