使用 Aspose.Cells for JavaScript 结合 C++ 向工作表添加图标
如果您需要使用Aspose.Cells在Excel文件中添加’图标'，那么本文档可以为您提供一些帮助。
对应于插入图标操作的Excel界面如下：
- 选择要插入到工作表中的图标的位置
- 左键单击插入->图标
- 在打开的窗口中，选择上图中红色矩形所示的图标
- 左键单击 插入，它将被插入到Excel文件中。
效果如下:
这里，我们准备了 示例代码 来帮助你使用 Aspose.Cells 插入图标。还包括必要的 示例文件 和图标 资源文件。我们使用Excel界面插入了一个图标，与 资源文件 在 示例文件 中具有相同的显示效果。
JavaScript

<title>Aspose.Cells Example</title>

<body>
<h1>Add Icon to Worksheet Example</h1>
<p>Select an Excel file and an SVG icon file, then click "Run Example".</p>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<input type="file" id="iconInput" accept=".svg" />
<button id="runExample">Run Example</button>

const { Workbook, SaveFormat, Color } = AsposeCells;
AsposeCells.onReady({

}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const iconInput = document.getElementById('iconInput');
const resultDiv = document.getElementById('result');
if (!fileInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
if (!iconInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select an SVG icon file.</p>';
return;
}
const file = fileInput.files[0];
const iconFile = iconInput.files[0];
const arrayBuffer = await file.arrayBuffer();
const iconArrayBuffer = await iconFile.arrayBuffer();
// Instantiating a Workbook object from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access first worksheet from the collection
const sheet = workbook.worksheets.get(0);
// Add the icon to the worksheet
const iconBytes = new Uint8Array(iconArrayBuffer);
sheet.shapes.addIcons(3, 0, 7, 0, 100, 100, iconBytes, null);
// Set a prompt message
const c = sheet.cells.get(8, 7);
c.value = "Insert via Aspose.Cells";
const s = c.style;
s.font.color = Color.Blue;
c.style = s;
// Save and prepare download link
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'sample2.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
resultDiv.innerHTML = '<p style="color: green;">Icon added successfully! Click the download link to get the modified file.</p>';
});
</script>
