For get the pdf information, it need an instance of com.inet.pdfc.model.Document
For geting a specific page information use the method getPage(<pageindex>)
Document document = resultModel.getComparisonParameters().getFirstFile().getContent();
Page page = document.getPage( i );
And for all drawable elements
List<DrawableElement> list = page.getElementList().getList();
For further using the drawable element, it can be cast in the correct class for more information about the elements.
for( DrawableElement drawableElement : list ) {
switch( drawableElement.getType() ){
case Text:
TextElement textElement = (TextElement)drawableElement;
break;
case Shape:
ShapeElement shapeElement = (ShapeElement)drawableElement;
break;
case Image:
ImageElement imageElement = (ImageElement)drawableElement;
break;
}
