    Public Properties
     NameDescription
    Public PropertyReturns the horizontal code-block partition origin. Allowable values are 0 and 1, nothing else. (Inherited from CSJ2K.j2k.quantization.dequantizer.Dequantizer)
    Public PropertyReturns the vertical code-block partition origin. Allowable values are 0 and 1, nothing else. (Inherited from CSJ2K.j2k.quantization.dequantizer.Dequantizer)
    Public PropertyReturns the nominal tiles height (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public PropertyReturns the nominal tiles width (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)

    Public Methods
     NameDescription
    Public MethodOverridden. Returns the specified code-block in the current tile for the specified component, as a copy (see below).

    The returned code-block may be progressive, which is indicated by the 'progressive' variable of the returned 'DataBlk' object. If a code-block is progressive it means that in a later request to this method for the same code-block it is possible to retrieve data which is a better approximation, since meanwhile more data to decode for the code-block could have been received. If the code-block is not progressive then later calls to this method for the same code-block will return the exact same data values.

    The data returned by this method is always a copy of the internal data of this object, if any, and it can be modified "in place" without any problems after being returned. The 'offset' of the returned data is 0, and the 'scanw' is the same as the code-block width. See the 'DataBlk' class.

     
    Public Method (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the width in pixels of the specified component in the overall image, for the given resolution level.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the component subsampling factor in the horizontal direction, for the specified component. This is, approximately, the ratio of dimensions between the reference grid and the component itself, see the 'ImgData' interface desription for details.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the component subsampling factor in the vertical direction, for the specified component. This is, approximately, the ratio of dimensions between the reference grid and the component itself, see the 'ImgData' interface desription for details.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodOverridden. Returns the position of the fixed point in the output data for the specified component. This is the position of the least significant integral (i.e. non-fractional) bit, which is equivalent to the number of fractional bits. For instance, for fixed-point values with 2 fractional bits, 2 is returned. For floating-point data this value does not apply and 0 should be returned. Position 0 is the position of the least significant bit in the data. If the output data is 'float' then 0 is always returned.

    Note: Fractional bits are no more supported by JJ2000.

     
    Public MethodReturns the overall height of the image in pixels, for the given resolution level. This is the image's height without accounting for any component subsampling or tiling.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the horizontal coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid at the specified resolution level.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the vertical coordinate of the image origin, the top-left corner, in the canvas system, on the reference grid at the specified resolution level.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the overall width of the image in pixels, for the given resolution level. This is the image's width without accounting for any component subsampling or tiling.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodOverridden. Returns the specified code-block in the current tile for the specified component (as a reference or copy).

    The returned code-block may be progressive, which is indicated by the 'progressive' variable of the returned 'DataBlk' object. If a code-block is progressive it means that in a later request to this method for the same code-block it is possible to retrieve data which is a better approximation, since meanwhile more data to decode for the code-block could have been received. If the code-block is not progressive then later calls to this method for the same code-block will return the exact same data values.

    The data returned by this method can be the data in the internal buffer of this object, if any, and thus can not be modified by the caller. The 'offset' and 'scanw' of the returned data can be arbitrary. See the 'DataBlk' class.

     
    Public Method (Inherited from CSJ2K.j2k.quantization.dequantizer.Dequantizer)

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the horizontal coordinate of the upper-left corner of the specified resolution level in the given component of the current tile.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public MethodReturns the vertical coordinate of the upper-left corner of the specified resolution in the given component of the current tile.

    This default implementation returns the value of the source.

    (Inherited from CSJ2K.j2k.wavelet.synthesis.MultiResImgDataAdapter)
    Public Method (Inherited from CSJ2K.j2k.quantization.dequantizer.Dequantizer)
