Start with the TestController exportXls example and trace how JeecgTemplateExcelView, TemplateExportParams, and ImageEntity process the attached test.xlsx template and sign.png file. Reproduce the export with the shown Java 21 and AutoPoi versions, then verify that the image appears correctly in the generated workbook.
