```
public class ImageWriter
extends java.lang.Object
implements IFormatWriter
```
ImageWriter is the master file format writer for all supported formats. It uses one instance of each writer subclass (specified in writers.txt, or other class list source) to identify file formats and write data.

    Description copied from interface: IFormatHandler
    
    Returns the native data type of image planes for this reader, as returned by IFormatReader.openPlane(int, int, int, int, int) or IFormatWriter.savePlane(int, java.lang.Object). For most readers this type will be a byte array; however, some readers call external APIs that work with other types such as BufferedImage.
    
    Specified by:
    
    getNativeDataType in interface IFormatHandler
  - setId

public void setId(java.lang.String id)
           throws FormatException,
                  java.io.IOException
```
    Description copied from interface: IFormatHandler
    
    Sets the current file name.

    Description copied from interface: IPyramidHandler
    
    Return the number of resolutions for the current series. Resolutions are stored in descending order, so the largest resolution is first and the smallest resolution is last.
    
    Specified by:
    
    getResolutionCount in interface IPyramidHandler
  - getResolution
