テキストのウェブリンク

PDFlib で、テキストフローを作成して、テキストにウェブリンクを色づけして割り当てるサンプルプログラムです。

ウェブリンクテキストを表示するためには、matchbox および matchbox end インラインオプションを使って、マッチボックスを定義します。


/*
 * Weblink in Text:
 * Create a Textflow and integrate colorized Web links in the text
 *
 * Using the inline options "matchbox" and "matchbox end" define
 * matchboxes which are used to indicate the pieces of text on which the
 * Web links are to be placed.
 *
 * Required software: PDFlib/PDFlib+PDI/PPS 9
 * Required data: none
