- Method Detail
  - getDPI
```
public int getDPI()
```
    Return the DPI setting for this TIFFOptions.
    
    Returns:
    
    The current DPI setting.
  - getCompression
```
public String getCompression()
```
    Return the current compression setting fo this TIFFOptions.
    
    Returns:
    
    The current compression setting.
  - getByteOrder
```
public ByteOrder getByteOrder()
```
    Gets the byte order to use when saving a TIFF file.
    
    Returns:
    
    The byte order
  - setByteOrder
```
public void setByteOrder(ByteOrder byteOrder)
```
    Sets the byte order to use when saving a TIFF file.
    
    Parameters:
    
    byteOrder - The byte order to use, this can be either ByteOrder.BIG_ENDIAN or BYTEOrder.LITTLE_ENDIAN.
  - setRowsPerStrip
```
public void setRowsPerStrip(int rowsPerStrip)
```
    Sets the number of rows per strip to use when writing the TIFF file. When this value is set, the TIFF file will be a multi-strip file using this value for the number of rows per strip.
    
    Parameters:
    
    rowsPerStrip - The number of rows per strip in the output file. Use -1 to output the file as a single strip file.
  - getRowsPerStrip
```
public int getRowsPerStrip()
```
    Returns the number of rows per strip that will be used when saving a TIFF file.
    
    Returns:
    
    Number of rows per strip. If -1, this means that the TIFF file will be output as a single strip file.
  - isGrayscale
```
public boolean isGrayscale()
```
    Returns a flag indicating whether the document should be converted to grayscale before writing the output TIFF file.
    
    Returns:
    
    The value of the grayscale flag.
  - setGrayscale
```
public void setGrayscale(boolean grayscale)
```
    Sets the grayscale flag. When this is true, the library will convert the image to grayscale before exporting.
    
    Parameters:
    
    grayscale - The new value of the grayscale flag.
  - getDitherBW
```
public int getDitherBW()
```
    Gets the dithering option when converting images to black and white.
    
    Returns:
    
    The current dithering option
  - setDitherBW
```
public void setDitherBW(int ditherBW)
```
    Sets the dithering option when converting images to black and white. The possible values for this are DITHER_NONE and DITHER_FLOYD_STEINBERG
    
    Parameters:
    
    ditherBW - The new value of the dithering option
  - getJPEGQuality
```
public float getJPEGQuality()
```
    Gets the current setting for the JPEG quality. this is only used when the TIFF file is saved using JPEG compression, with TIFF_JPEG. The value is between 0 and 1.
    
    Returns:
    
    The current setting for the JPEG quality.
  - setJPEGQuality
```
public void setJPEGQuality(float jpegQuality)
```
    Sets the JPEG quality to be used when saving a JPEG compressed TIFF file. This value only gets used when the compression type is TIFF_JPEG.
    
    Parameters:
    
    jpegQuality - The JPEG quality setting, should be between 0 and 1.
