Add Transitions
This exercise will demonstrate how to transition between objects.
Transitions are used to make the change from one picture to another
more fluid.
To create transitions define your transitions by adding <transition>
elements to the <head> section of the document.
Transitions are governed by their type and subtype. The transitions
used in this example are a few of the standardized SMPTE transitions.
<xmt-o ...>
<head>
...
<transition id="transBoxWipe" type="boxWipe" subtype="bottomRight" dur="2s"/>
<transition id="transfourBoxWipe" type="fourBoxWipe" subtype="cornersOut" dur="2s"/>
<transition id="transSnakeWipe" type="snakeWipe" subtype="topLeftHorizontal" dur="2s" />
...
</head>
<body> ... </body>
</xmt-o>
The transition is used by specifying the transIn attribute on the
media object. The transOut attribute can be specified to indicate
a transition to be used for the removal of the media object.
The timing is adjusted to allow for overlapping of the pictures.
Since the transitions last 2 seconds the picture will begin 2 seconds
before the previous picture ended. The durations are changed 12
seconds to compensate for the overlap.
<xmt-o ...>
<head> ... </head>
<body>
<par>
...
<img ... begin="0s" dur="12s"/>
<img ... begin="slide1.end-2s" dur="12s" transIn="transBoxWipe"/>
<img ... begin="slide2.end-2s" dur="12s" transIn="transfourBoxWipe"/>
<img ... begin="slide3.end-2s" dur="indefinite" transIn="transSnakeWipe"/>
...
</par>
</body>
</xmt-o>

credits at the end using groups and various graphic objects.
