    CompressionQuality quality,
    int numberClusters,
    int numberPca,
    PercentageCompleteCallback^ callback,
    PrtBuffer^ buffer

JScript public function PrtCompressedBuffer(
    quality : CompressionQuality,
    numberClusters : int,
    numberPca : int,
    callback : PercentageCompleteCallback,
    buffer : PrtBuffer
);

Parameters

quality Microsoft.DirectX.Direct3D.CompressionQuality
Quality of spherical harmonic (SH) compression.
numberClusters System.Int32
Number of clusters to use for compression.
numberPca System.Int32
Number of principal component analysis (PCA) basis vectors to use in each cluster.
callback Microsoft.DirectX.Direct3D.PercentageCompleteCallback
PercentageCompleteCallback delegate that represents the optional callback method used to compute the percentage of precomputed radiance transfer (PRT) compression computations completed.
buffer Microsoft.DirectX.Direct3D.PrtBuffer
Uncompressed PrtBuffer object to compress.

Remarks

The PrtCompressedBuffer constructor creates a compressed PRT buffer from an uncompressed PrtBuffer object.
