JFreeChartをItext 5から7に移行

Question

私のアプリをItext 5から7に移行していて、ドキュメントにJFreeChartを追加する方法が見つかりません。私はそのフォーラムで尋ねたが、彼らは私がここに私を送ったので彼らを助けることができなかった。ここに私の働いているItext 5のコードです：

PdfContentByte cb=writer.getDirectContent(); 
PdfTemplate tp=cb.createTemplate(sizeX*scale+1,sizeY*scale+1); 
PdfGraphics2D g2d=new PdfGraphics2D(cb,sizeX*scale+1,sizeY*scale+1); 
tp.setWidth(sizeX*scale+1); 
tp.setHeight(sizeY*scale+1); 
Chart.getInstance().getChart().draw(g2d, new java.awt.geom.Rectangle2D.Float(0,0,sizeX*scale,sizeY*scale)); 
g2d.dispose(); 
cb.add(tp); 

誰かがitext 7等価物を作成するのを助けることができますか？ TIA。

Answer 1

私が理解しているように、iTextはPdfGraphics2Dクラスを削除しました。あなたが試みる可能性のあるアプローチの1つは、PDFGraphics2Dの実装にOrsonPDFを使用して（チャートのPDF版を作成する）、それをiTextによって作成されたPDFに埋め込むことです。私はここでそのことについてブログ記事を書いた：ここ

https://jfree.github.io/orsonpdf/

は、ソースコード（はJFreeChart 1.5.0、OrsonPDF 1.7以降、およびiTextの7を必要とする - 私は7.0.4を使用）です：
