在通过 C++ 采用 JavaScript 转换 Excel 为 PDF 时渲染 Office 插件

可能的使用场景
早期，Aspose.Cells 在将 Excel 文件保存为 PDF 格式时无法渲染 Office 插件。现在 Aspose.Cells 可以正常渲染。您无需使用任何特殊方法或属性来在输出 PDF 中渲染 Office 插件。只需将您的 Excel 文件保存为 PDF 格式，它将自动渲染 Office 插件。
在将Excel转换为PDF时呈现Office加载项
以下示例代码保存了包含Office加载项的示例Excel文件。请查看之前版本（即17.11）生成的输出PDF和较新版本（即17.12及之后版本）生成的输出PDF。之前版本的输出PDF为空白，但较新版本的输出PDF显示了Office加载项。
示例代码

<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Run Example</button>
<a id="downloadLink" style="display: none;">Download Result</a>
