```
public class SoRasterReaderSet
extends Inventor
```
Class referencing all raster reading classes. This class is used to know what readers are available when opening a raster file. All raster readers supplied by Open Inventor are already referenced in SoRasterReaderSet as default readers. The default raster readers are: SoPNGImageRW, SoSGIRGBImageRW, SoGIFImageRW, SoJP2ImageRW, SoSUNImageRW, SoBMPImageRW, SoPGXImageRW, SoPNMImageRW, SoPSImageRW, SoJPEGImageRW, and SoTIFFImageRW.

- Method Detail
  - deleteReaders
```
public static void deleteReaders(int start)
```
    Calls deleteReaders(start, (int)-1).
  - addReader
```
public static void addReader(SoRasterImageRW reader)
```
    Adds a raster reading class to the set of raster readers.
  - getReader
```
public static SoRasterImageRW getReader(SoRasterImageIO imageIO)
```
    Returns an instance of the reader class if found in the set of raster readers. Returns NULL if no reader found or available.
  - getNumReaders
```
public static int getNumReaders()
```
    Returns the number of raster readers currently in the set.
  - getReaderAt
```
public static java.lang.Class<? extends Inventor> getReaderAt(int index)
```
    Returns the type of reader at the specified index.
  - deleteReaders
```
public static void deleteReaders(int start,
                                 int num)
```
    Removes num readers (including default ones) at start position. If num is equal to -1, all readers are removed.
