HCompressorOption

public HCompressorOption()

Method Detail

copy

public HCompressorOption copy()

Specified by:

copy in interface ICompressOption

Returns:

copy the option (normally the option from with the copy happened is saved as original).

getCompressionParameters

public ICompressParameters getCompressionParameters()

Specified by:

getCompressionParameters in interface ICompressOption

Returns:

the parameters that must be synchronized with the hdu meta data.

getScale

public int getScale()

getTileHeight

public int getTileHeight()

getTileWidth

public int getTileWidth()

isLossyCompression

public boolean isLossyCompression()

Specified by:

isLossyCompression in interface ICompressOption

Returns:

true if the compression done with this specified options uses approximations. That means if the reconstruction of the data is excact the return should be false.

isSmooth

public boolean isSmooth()

setParameters

public void setParameters(ICompressParameters parameters)

Description copied from interface: ICompressOption

set the parameters that must be synchronized with the hdu meta data.

Specified by:

setParameters in interface ICompressOption

Parameters:

parameters - the parameters to synchronized

setScale

public HCompressorOption setScale(int value)

setSmooth

public HCompressorOption setSmooth(boolean value)

setTileHeight

public HCompressorOption setTileHeight(int value)

Description copied from interface: ICompressOption

set the tile height in pixel.

Specified by:

setTileHeight in interface ICompressOption

Parameters:

value - the number of pixel.

Returns:

this (builder pattern)

setTileWidth

public HCompressorOption setTileWidth(int value)

Description copied from interface: ICompressOption

set the tile width.

Specified by:

setTileWidth in interface ICompressOption

Parameters:

value - the number of pixel.

Returns:

this (builder pattern)

unwrap

public <T> T unwrap(java.lang.Class<T> clazz)

Description copied from interface: ICompressOption

un wrap a specific implementation detail.

Specified by:

unwrap in interface ICompressOption

Type Parameters:

T - the class to unrwap

Parameters:

clazz - the type to unwrap

Returns:

the implementation detail or null if no such detail is avalable.
