PDFlib サンプル集(クックブック)

本サンプルプログラムは、PDF 文書生成ライブラリーの実装である PDFlib の基本的な機能を実際のプログラムで紹介したものです。

本サイトでダウンロードした PDFlib は、一部機能の制限を除き、評価版として無償でお使いいただけます。

疑似フォントスタイル

PDFlib で、ボールドやイタリックテキスト出力を疑似的に行うサンプルプログラムです。

テキストラインとボールドで傾斜するテキストフローを出力します。これは、実際にイタリックやボールドの内容がフォントに提供されていない場合に使用されます。


/*
 * Simulated font styles:
 * Create simulated italic or bold text output
 * 
 * Output text lines and Textflows with simulated obliqued or bold font, which
 * is useful if a real italic or bold variant of the font is not available.
 * 
 * Required software: PDFlib/PDFlib+PDI/PPS 9
 * Required data: font
