PDF Tool APIサンプルコード：パス（矩形、線、多角形、折れ線描画）の描画
PDF文書のページ上にパス（矩形、線、多角形、折れ線描画）を描画します。
概要
サンプルコードの概要
PDF文書のページ上にパス（丸角矩形・矩形・楕円・線・多角形・折れ線描画）を描画します。
- PtlContent.drawRoundRect(PtlRect, float, float, PtlParamDrawShape) :丸角矩形の描画
- PtlContent.drawRect(PtlRect, PtlParamDrawShape) :矩形の描画
- PtlContent.drawCircle(PtlRect, PtlParamDrawShape) :円形（楕円または円）の描画
- PtlContent.drawLine(PtlPoint, PtlPoint, PtlParamDrawShape) :線の描画
