可能的使用场景
在Aspose.Cells 17.1之前，转换为HTML格式时不支持WordArt的渐变填充。从Aspose.Cells 17.1版本开始，支持WordArt渐变填充。以下截图比较了使用Aspose.Cells 17.1和旧版本转换Excel文件时渐变填充的效果。
在将电子表格转换为HTML时渲染WordArt的渐变填充
以下示例代码将源Excel文件转换成输出HTML格式。源Excel文件中包含带有渐变填充的WordArt对象，如上截图所示。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example - Source Gradient Fill</title>
</head>
<body>
<h1>Source Gradient Fill to HTML Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample">Convert to HTML</button>
<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">
const { Workbook, SaveFormat, Utils } = AsposeCells;
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
});
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const resultDiv = document.getElementById('result');
if (!fileInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file (.xls, .xlsx, .csv).</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiating a Workbook object by opening the uploaded Excel file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Save workbook to HTML format
const outputData = workbook.save(SaveFormat.Html);
const blob = new Blob([outputData], { type: 'text/html' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'out_sourceGradientFill.html';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Converted HTML File';
resultDiv.innerHTML = '<p style="color: green;">Conversion completed successfully! Click the download link to get the HTML file.</p>';
});
</script>
