class PushbuttonField
extends BaseField

Creates a pushbutton field. It supports all the text and icon alignments. The icon may be an image or a template.

Example usage:

 Document document = new Document(PageSize.A4, 50, 50, 50, 50);
 PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
 document.open();
 PdfContentByte cb = writer.getDirectContent();
 Image img = Image.getInstance("image.png");
 PushbuttonField bt = new PushbuttonField(writer, new Rectangle(100, 100, 200, 200), "Button1");
 bt.setText("My Caption");
 bt.setFontSize(0);
 bt.setImage(img);
 bt.setLayout(PushbuttonField.LAYOUT_ICON_TOP_LABEL_BOTTOM);
 bt.setBackgroundColor(Color.cyan);
 bt.setBorderStyle(PdfBorderDictionary.STYLE_SOLID);
 bt.setBorderColor(Color.red);
 bt.setBorderWidth(3);
 PdfFormField ff = bt.getField();
 PdfAction ac = PdfAction.createSubmitForm("http://www.submit-site.com", null, 0);
 ff.setAction(ac);
 writer.addAnnotation(ff);
 document.close();
