```
public PDFormXObject(PDDocument document)
```
    Creates a Form Image XObject for writing, in the given document.
    
    Parameters:
    document - The current document
- Method Detail
  - getFormType
```
public int getFormType()
```
    This will get the form type, currently 1 is the only form type.
    
    Returns:
    The form type.
  - setFormType
```
public void setFormType(int formType)
```
    Set the form type.
    
    Parameters:
    formType - The new form type.
  - getGroup
```
public PDTransparencyGroupAttributes getGroup()
```
    Returns the group attributes dictionary.
    
    Returns:
    the group attributes dictionary
  - getContentStream
```
public PDStream getContentStream()
```
  - getContents
```
public InputStream getContents()
                        throws IOException
```
    Description copied from interface: PDContentStream
    
    Returns this stream's content, if any.
    
    Specified by:
    
    getContents in interface PDContentStream
    
    Returns:
    An InputStream or null.
    
    Throws:
    
    IOException - If the stream could not be read
  - getResources
```
public PDResources getResources()
```
    This will get the resources for this Form XObject. This will return null if no resources are available.
    
    Specified by:
    
    getResources in interface PDContentStream
    
    Returns:
    The resources for this Form XObject.

```
    This will set the resources for this page.
    
    Parameters:
    resources - The new resources for this page.
  - getBBox
```
public PDRectangle getBBox()
```
    An array of four numbers in the form coordinate system (see below), giving the coordinates of the left, bottom, right, and top edges, respectively, of the form XObject's bounding box. These boundaries are used to clip the form XObject and to determine its size for caching.
    
    Specified by:
    
    getBBox in interface PDContentStream
    
    Returns:
    The BBox of the form.
  - setBBox
```
public void setBBox(PDRectangle bbox)
```
    This will set the BBox (bounding box) for this form.
    
    Parameters:
    bbox - The new BBox for this form.
  - getMatrix
```
public Matrix getMatrix()
```
    This will get the optional Matrix of an XObjectForm. It maps the form space to user space.
    
    Specified by:
    
    getMatrix in interface PDContentStream
    
    Returns:
    the form matrix if available, or the identity matrix.
  - setMatrix
```
public void setMatrix(AffineTransform transform)
```
    Sets the optional Matrix entry for the form XObject.
    
    Parameters:
    transform - the transformation matrix
  - getStructParents
```
public int getStructParents()
```
    This will get the key of this XObjectForm in the structural parent tree. Required if the form XObject contains marked-content sequences that are structural content items.
    
    Returns:
    the integer key of the XObjectForm's entry in the structural parent tree
  - setStructParents
```
public void setStructParents(int structParent)
```
    This will set the key for this XObjectForm in the structural parent tree.
    
    Parameters:
    structParent - The new key for this XObjectForm.
