我想通过iText将我的Swing JComponent打印到pdf。
JComponent com = new JPanel(); com.add( new JLabel("hello") ); PdfWriter writer = PdfWriter.getInstance( document, new FileOutputStream( dFile ) ); document.open( ); PdfContentByte cb = writer.getDirectContent( ); PdfTemplate tp = cb.createTemplate( pageImageableWidth, pageImageableHeight ); Graphics2D g2d = tp.createGraphics( pageImageableWidth, pageImageableHeight, new DefaultFontMapper( ) ); g2d.translate( pf.getImageableX( ), pf.getImageableY( ) ); g2d.scale( 0.4d, 0.4d ); com.paint( g2d ); cb.addTemplate( tp, 25, 200 ); g2d.dispose( );
不幸的是,PDF文件中未显示任何内容。你知道如何解决这个问题吗?
