 * optional content group (OCG), here used as a layer. This optional group is returned and
 * can be enabled and disabled through methods on {@link PDOptionalContentProperties}.
 * <p>
 * You may want to call {@link #wrapInSaveRestore(PDPage) wrapInSaveRestore(PDPage)} before calling this method to make
 * sure that the graphics state is reset.
 *
 * @param targetPage the target page
 * @param form the form to place
 * @param transform the transformation matrix that controls the placement of your form. You'll
 * need this if your page has a crop box different than the media box, or if these have negative
 * coordinates, or if you want to scale or adjust your form.
 * @param layerName the name for the layer/OCG to produce
 * @return the optional content group that was generated for the form usage
 * @throws IOException if an I/O error occurs
