This is a simple way:
PdfAnnotation annotation = PdfAnnotation.createSquareCircle(
writer, rect, text, true);
annotation.put(PdfName.T, new PdfString(text));
annotation.put(PdfName.CONTENTS, null);
float[] red = { 1, 0, 0 };
annotation.put(PdfName.C, new PdfArray(red));
It creates a red Square annotation (defined by a Rectangle rect).
When somebody hovers over it, the String text is shown.
This is another possibility:
PdfAnnotation annotation =
PdfAnnotation.createText(writer, rect, "tooltip", text, false, null);
PdfAppearance ap = writer.getDirectContent().createAppearance(rect.getWidth(),
rect.getHeight());
annotation.setAppearance(PdfAnnotation.APPEARANCE_NORMAL, ap);
float[] red = { 1, 0, 0 };
annotation.put(PdfName.C, new PdfArray(red));
It creates a Text annotation.
There may be many other different possibilities.
Please read ISO-32000-1 to find the type of annotation that meets your needs.
(I can't decide in your place; I don't know EXACTLY what you want.)
