Package jj2000.j2k.image
Class DataBlkFloat
java.lang.Object
jj2000.j2k.image.DataBlk
jj2000.j2k.image.DataBlkFloat
This is an implementation of the DataBlk interface for
32 bit floating point data (float).
The methods in this class are declared final, so that they can be inlined by inlining compilers.

DataBlkFloat
public DataBlkFloat()Creates a DataBlkFloat with 0 dimensions and no data array (i.e. data is null). -
DataBlkFloat
public DataBlkFloat(int ulx, int uly, int w, int h) Creates a DataBlkFloat with the specified dimensions and position. The data array is initialized to an array of size w*h.- Parameters:
ulx- The horizontal coordinate of the upper-left corner of the blockuly- The vertical coordinate of the upper-left corner of the blockw- The width of the block (in pixels)h- The height of the block (in pixels)
-
DataBlkFloat
Copy constructor. Creates a DataBlkFloat which is the copy of the DataBlkFloat given as paramter.- Parameters:
src- the object to be copied.

getDataType
public final int getDataType()Returns the identifier of this data type, TYPE_FLOAT, as defined in DataBlk.- Specified by:
getDataTypein classDataBlk- Returns:
- The type of data stored. Always DataBlk.TYPE_FLOAT

-
getData
Returns the array containing the data, or null if there is no data array. The returned array is a float array. -
getDataFloat
public final float[] getDataFloat()Returns the array containing the data, or null if there is no data array.- Returns:
- The array of data or null if there is no data.
-
setData
Sets the data array to the specified one. The provided array must be a float array, otherwise a ClassCastException is thrown. The size of the array is not checked for consistency with the block's dimensions. -
setDataFloat
public final void setDataFloat(float[] arr) Sets the data array to the specified one. The size of the array is not checked for consistency with the block's dimensions.- Parameters:
arr- The data array to use.
-
toString
Returns a string of informations about the DataBlkInt.
