public PDAnnotationTextMarkup(String subType) 
{
        super();
        setSubtype( subType );
        // Quad points are required, set and empty array
        setQuadPoints( new float[0] );
}

Creates a TextMarkup annotation of the specified sub type.

Parameters:

subType - the subtype the annotation represents

 public PDAnnotationTextMarkup(COSDictionary field) 
{
        super( field );
}

Creates a TextMarkup annotation from a COSDictionary, expected to be a correct object definition.

Parameters:

field - the PDF objet to represent as a field.

 public float[] getQuadPoints() 
{
        COSArray quadPoints = (COSArray) getDictionary().getDictionaryObject( "QuadPoints" );
        if (quadPoints != null)
        {
            return quadPoints.toFloatArray();
        }
        else
        {
            return null; // Should never happen as this is a required item
        }
}

This will retrieve the set of quadpoints which encompass the areas of this annotation.

 public String getSubtype() 
{
        return getDictionary().getNameAsString( COSName.SUBTYPE);
}

This will retrieve the sub type (and hence appearance, AP taking precedence) For this annotation.

 public  void setQuadPoints(float[] quadPoints) 
{
        COSArray newQuadPoints = new COSArray();
        newQuadPoints.setFloatArray( quadPoints );
        getDictionary().setItem( "QuadPoints", newQuadPoints );
}

This will set the set of quadpoints which encompass the areas of this annotation.

 public  void setSubtype(String subType) 
{
        getDictionary().setName( COSName.SUBTYPE, subType );
}

This will set the sub type (and hence appearance, AP taking precedence) For this annotation. See the SUB_TYPE_XXX constants for valid values.
