    Public Fields
     NameDescription
    Public FieldDefaultAllocatorSizeThe default value for the 'allocator size' PPMd compression property. The value represents megabytes of memory.  
    Public FieldDefaultModelOrderThe default value for the 'maximum model order' PPMd compression property.  
    Public FieldDefaultModelRestorationMethodThe default value for the 'model restoration method' PPMd compression property.  
    Public FieldMaxAllocatorSizeThe maximum allowed value for the 'allocator size' PPMd compression property. The value represents megabytes of memory.  
    Public FieldMaxModelOrderThe maximum allowed value for the 'maximum model order' PPMd compression property.  
    Public FieldMinAllocatorSizeThe minimum allowed value for the 'allocator size' PPMd compression property. The value represents megabytes of memory.  
    Public FieldMinModelOrderThe minimum allowed value for the 'maximum model order' PPMd compression property.  
    Public FieldSignatureThe binary signature of the PPMd algorithm.  
    Public FieldVariantThe variant signature of the PPMd algorithm the component implements.

    Public Methods
     NameDescription
    Public MethodCompressOverloaded. Overridden. Compresses an array of bytes.  
    Public Methodstatic (Shared in Visual Basic)ComputePPMdOptionsComputes the correct values of the PPMd algorithm properties based on the specified compression level.  
    Public MethodCreateCompressorStream (Inherited from Xceed.Compression.Compressor)
    Public MethodDisposeOverloaded. Provides correct cleanup of resources in the base class and its derived classes.  
    Public Methodstatic (Shared in Visual Basic)WritePPMdZipHeaderWrites the PPMd algorithm properties in the specified stream using the Zip Specification format.
