PDFlib サンプル集(クックブック)
PDFlib で、イメージが保有するクリッピングパス情報に基づき、イメージを切り抜いて表示するサンプルプログラムです。
クリッピングパスを含んだイメージを使います。クリッピングパスを使わずに配置し、クリッピングパスに従ってイメージを切り抜きます。
必要な製品:PDFlib または PDFlib+PDI または PPS
/*
* Integrated clipping path:
* Place an image with its integrated clipping path being applied to it

* Use an image containing a clipping path. Place it without any clipping
* taken place. Then, place the image clipped according to its clipping path.
*
* Required software: PDFlib/PDFlib+PDI/PPS 10
* Required data: image file with integrated clipping path
