Parfois, vous avez besoin de copier des éléments d’une feuille de calcul, par exemple, des images, des graphiques et d’autres objets de dessin, entre les feuilles. Aspose.Cells for JavaScript via C++ supporte cette fonctionnalité. Les graphiques, images et autres objets peuvent être copiés avec la plus haute précision.
Cet article vous donne une compréhension détaillée de comment copier des formes entre les feuilles de calcul.
Copier une image d’une feuille de calcul à une autre
Pour copier une image d’une feuille de calcul à une autre, utilisez la méthode PictureCollection.add(number, number, number, number, Uint8Array) comme indiqué dans le code exemple ci-dessous.

AsposeCells.onReady({

"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.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiate Workbook from uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Get the Picture from the "Picture" worksheet.
const pictureSheet = workbook.worksheets.get("Picture");
const pictureSource = pictureSheet.pictures.get(0);
// Save Picture to Memory (property access converted from getData())
const ms = pictureSource.data;
// Copy the picture to the Result Worksheet (properties converted)
const resultSheet = workbook.worksheets.get("Result");
resultSheet.pictures.add(
pictureSource.upperLeftRow,
pictureSource.upperLeftColumn,
ms,
pictureSource.widthScale,
pictureSource.heightScale
);
// Save the modified workbook and provide download link
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'PictureCopied_out.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
resultDiv.innerHTML = '<p style="color: green;">Picture copied successfully! Click the download link to get the modified file.</p>';
});
