使用DynamicReports API将图像渲染为XLS报告

Question

I want to render image from a folder and display in Excel report.

Following codes used to render.

String headerImagePath = "/file/fileName.jpg"
BufferedImage img = null;

try {
    img = ImageIO.read(new File(headerImagePath)); 

}  catch (IOException e)  {
    e.printStackTrace();
}
JasperReportBuilder report = report();
report.title(cmp.image(img));

But image is not showing in excel sheet.

Any other option to render an image?

Answer 1

Are you sure that the image path is correct?

You can check that easily by running:

System.out.println(new File(headerImagePath).exists());

If this code outputs false then you need to correct the path.

Answer 2

Finally got it.!

You need pass the image file name as a parameter.

     parameters.put("header", headerImagePath);

Add the above parameters & it's Class to Jasper Report.

     report.addParameter("header", String.class);

You can add the image to report as follows

     report.title(cmp.image(exp.jasperSyntax("($P{header})",String.class)).setDimension(50, 130));
