| EBCOTLayer | | class EBCOTLayer (Code) | | This class holds information about each layer that is to be, or has already
been, allocated . It is used in the rate-allocation process to keep the
necessary layer information. It is used by EBCOTRateAllocator.

| Field Summary | |
| int | actualBytes
The actual number of bytes which are consumed by the the current and
any previous layers. | | int | maxBytes
This is the maximum number of bytes that should be allocated for
this and previous layers. | | boolean | optimize
If true the `maxBytes' value is the hard maximum and the threshold is
determined iteratively. | | float | rdThreshold
The rate-distortion threshold associated with the bit-stream
layer. |
| actualBytes | | int actualBytes(Code) | | The actual number of bytes which are consumed by the the current and
any previous layers. This is the result from a simulation when the
threshold for the layer has been set.
|
| maxBytes | | int maxBytes(Code) | | This is the maximum number of bytes that should be allocated for
this and previous layers. This is actually the target length for
the layer.
|
| optimize | | boolean optimize(Code) | | If true the `maxBytes' value is the hard maximum and the threshold is
determined iteratively. If false the `maxBytes' value is a target
bitrate and the threshold is estimated from summary information
accumulated during block coding.
|
| rdThreshold | | float rdThreshold(Code) | | The rate-distortion threshold associated with the bit-stream
layer. When set the layer includes data up to the truncation points
that have a slope no smaller than 'rdThreshold'.
