|
// If the image is mapped onto a surface with texture coordinates |
|
// outside the zero-to-one range, then the image must be extrapolated. |
|
// This attribute tells the renderer how to do this extrapolation. |
|
// The attribute contains either a pair of comma-separated keywords, |

// vertical directions; or a single keyword, to specify extrapolation |
|
// in both directions (e.g. "clamp,periodic" or "clamp"). Extra white |

// no framesPerSecond attribute, playback software should assume that |
|
// the frame rate for the sequence is 24 frames per second. |

|
// framesPerSecond is stored as a rational number. A rational number is |
