【问题原因】接口使用错误
【解决办法】应该使用ExportSetting，并将导出类型设置为IMG：ExportSetting exportSetting = new ExportSetting();
exportSetting.setTargetFileType(FileType.IMG);
exportSetting.setTargetFilePath("C:\Users\Administrator\Desktop\影像\test100.img");
exportSetting.setSourceData(dataset);
DataExport dataExport = new DataExport();
ExportSettings exportSettings = new ExportSettings();
exportSettings.add(exportSetting);
dataExport.setExportSettings(exportSettings);
dataExport.run();
