如何以编程方式在jasper标题中设置图像

我正在创建JR未使用报告jrxml模板。我需要知道如何设置Java代码的报告标题中的图像？如何以编程方式在jasper标题中设置图像

 
    
    ... 
    //Title 
    band = new JRDesignBand(); 
    band.setHeight(50); 
    textField = new JRDesignTextField(); 
    textField.setBlankWhenNull(true); 
    textField.setX(0); 
    textField.setY(10); 
    textField.setWidth(515); 
    textField.setHeight(30); 
    textField.setHorizontalAlignment(HorizontalAlignEnum.CENTER); 
    textField.setStyle(normalStyle); 
    textField.setFontSize(22); 
    expression = new JRDesignExpression(); 
    expression.setValueClass(java.lang.String.class); 
    expression.setText("$P{ReportTitle}"); 
    textField.setExpression(expression); 
    band.addElement(textField); 
    jasperDesign.setTitle(band);

这里，而不是文本字段我需要添加一个图像。我该怎么办？

可以使用JRDesignImage类设置图像。

样品：

public JasperDesign getJasperDesign() throws JRException { 
    JasperDesign jasperDesign = new JasperDesign(); 
    jasperDesign.setName(DESIGN_NAME); 
    jasperDesign.setPageWidth(595); 
    jasperDesign.setPageHeight(842); 
    jasperDesign.setColumnWidth(515); 
    jasperDesign.setColumnSpacing(0); 
    jasperDesign.setLeftMargin(40); 
    jasperDesign.setRightMargin(40); 
    jasperDesign.setTopMargin(50); 
    jasperDesign.setBottomMargin(50); 

    JRDesignParameter parameter = new JRDesignParameter(); 
    parameter.setName("ReportTitle"); 
    parameter.setValueClass(java.lang.String.class); 
    jasperDesign.addParameter(parameter); 

    //Title band 
    JRDesignBand band = new JRDesignBand(); 
    band.setHeight(250); 

    JRDesignTextField textField = new JRDesignTextField(); 
    textField.setBlankWhenNull(true); 
    textField.setX(0); 
    textField.setY(10); 
    textField.setWidth(515); 
    textField.setHeight(30); 
    textField.setHorizontalAlignment(HorizontalAlignEnum.CENTER); 
    textField.setFontSize(22); 
    JRDesignExpression expression = new JRDesignExpression(); 
    expression.setValueClass(java.lang.String.class); 
    expression.setText("$P{ReportTitle}"); 
    textField.setExpression(expression); 
    band.addElement(textField); 

    // Image 
    String imgPath = "\"dukesign.jpg\""; 

    expression = new JRDesignExpression(); 
    expression.setText(imgPath); 

    JRDesignImage image = new JRDesignImage(jasperDesign); 
    image.setX(45); 
    image.setY(55); 
    image.setWidth(130); 
    image.setHeight(104); 
    image.setScaleImage(ScaleImageEnum.FILL_FRAME); 
    image.setExpression(expression); 

    // Add image to Detail band 
    band.addElement(image); 

    jasperDesign.setTitle(band); 

    return jasperDesign; 
}

其结果将是（生成的PDF文件）：

感谢。它正在处理你的代码。在你的代码中，你错过了为表达式设置“表达式类”。 –
