ZK Spreadsheet uses Range.addPicture (ClientAnchor, byte[], int) to insert a new picture into the sheet.


<window vflex="1" width="100%" 
    <spreadsheet id="myss" src="/WEB-INF/excel/config/addPicture.xlsx" maxrows="200"
        maxcolumns="40" vflex="1" width="100%">
    <button id="add" label="Add Picture" upload="true"/>


We use onUpload to get the picture byte stream data to be inserted into the sheet. Besides the picture byte stream data, user have to specify where to anchor the picture, too.

	private Spreadsheet myss;
	public void onUpload$add(UploadEvent evt) throws Exception {
		final Media media = evt.getMedia();
		byte[] image = media.getByteData();
		//add a picture
		Worksheet sheet = myss.getSelectedSheet();
		Range rng = Ranges.range(sheet);
		ClientAnchor anchor = new XSSFClientAnchor(0, 0, 0, 0, 2, 1, 7, 11); //C2:H12
		String fmt = media.getFormat();
		rng.addPicture(anchor, image, PictureHelper.getPictureFormat(fmt));
