| Name | Description | |
|---|---|---|
 | h | The height of the block, in pixels. |
| offset | The offset in the array of the top-left coefficient |
| progressive | The progressive attribute (false by default) |
| scanw | The width of the scanlines used to store the data in the array |
| TYPE_BYTE | The identifier for the System.Byte data type, as signed 8 bits. |
| TYPE_FLOAT | The identifier for the System.Single data type |
| TYPE_INT | The identifier for the System.Int32 data type, as signed 32 bits. |
| TYPE_SHORT | The identifier for the System.Int16 data type, as signed 16 bits. |
| ulx | The horizontal coordinate (in pixels) of the upper-left corner of the block of data. This is relative to the component of the image from where this block was filled or is to be filled. |
| uly | The vertical coordinate of the upper-left corner of the block of data. This is relative to the component of the image from where this block was filled or is to be filled. |
| w | The width of the block, in pixels. |

Public Fields
Public Methods
| Name | Description | |
|---|---|---|
 | getData | Returns the array containing the data, or null if there is no data. The returned array is of the type returned by getDataType (e.g., for TYPE_INT, it is a int[]).
Each implementing class should provide a type specific equivalent method (e.g., getDataInt() in GrapeCity.Documents.Imaging.jpeg.jj2000.j2k.image.DataBlkInt) which returns an array of the correct type explicitly and not through an System.Object. |
| getDataType | Returns the data type of the DataBlk object, as defined in this class. |
 | getSize | Returns the size in bits, given the data type. The data type must be one defined in this class. An System.ArgumentException is thrown if type is not defined in this class. |
| setData | Sets the data array to the specified one. The type of the specified data array must match the one returned by getDataType (e.g., for TYPE_INT, it should be a int[]). If the wrong type of array is given a System.Exception will be thrown.
The size of the array is not necessarily checked for consistency with w and h or any other fields. Each implementing class should provide a type specific equivalent method (e.g., setDataInt() in GrapeCity.Documents.Imaging.jpeg.jj2000.j2k.image.DataBlkInt) which takes an array of the correct type explicitly and not through an System.Object. |
| ToString | Returns a string of informations about the DataBlk |
