-----------------------------------------
Here's code that creates a push button with an image. The position is set only
in the widget rectangle, not in the BBox and not in the content stream.
{code}
PDDocument doc = new PDDocument();
PDPage page = new PDPage();
doc.addPage(page);
PDAcroForm acroForm = new PDAcroForm(doc);
doc.getDocumentCatalog().setAcroForm(acroForm);
PDPushButton pushButton = new PDPushButton(acroForm);
pushButton.setPartialName("push");
acroForm.getFields().add(pushButton);
PDAnnotationWidget widget = pushButton.getWidgets().get(0);
page.getAnnotations().add(widget);
widget.setRectangle(new PDRectangle(50, 500, 100, 100)); // position on the page
widget.setPrinted(true);
widget.setPage(page);
PDActionJavaScript javascriptAction = new
PDActionJavaScript("app.alert(\"button pressed\")");
PDAnnotationAdditionalActions actions = new PDAnnotationAdditionalActions();
actions.setU(javascriptAction);
widget.setActions(actions);
// Create a PDFormXObject
PDFormXObject form = new PDFormXObject(doc);
form.setResources(new PDResources());
form.setBBox(new PDRectangle(100, 100));
form.setFormType(1);
PDAppearanceDictionary appearanceDictionary = new PDAppearanceDictionary(new
COSDictionary());
widget.setAppearance(appearanceDictionary);
PDAppearanceStream appearanceStream = new
PDAppearanceStream(form.getCOSObject());
appearanceDictionary.setNormalAppearance(appearanceStream);
// Create the content stream
BufferedImage bim = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB); //
black
PDImageXObject image = LosslessFactory.createFromImage(doc, bim);
try (PDAppearanceContentStream cs = new
PDAppearanceContentStream(appearanceStream))
{
cs.drawImage(image, 0, 0);
}
doc.save("button.pdf");
acroForm.flatten();
doc.save("button-flat.pdf");
doc.close();
{code}
