Open the demo in new window can open the designer
This demo shows how to add a watermark-style background image to a ReportSheet.
Set the background image for the ReportSheet and set paintOrder to over-content to draw the image above the cell content. This is useful for report watermarks such as draft marks, approval stamps, company logos, or other visual indicators that should remain visible on top of the generated report.
Sample Code
window.onload = async () => {
const loadingTip = addLoadingTip();
const { spread, designer } = createSpreadAndDesigner();
const res = await fetch('$DEMOROOT$/en/sample/features/report-sheet/rendering-features/watermark/spread.json');
await spread.fromJSON(await res.json());
loadingTip.remove();
if (designer) {
designer.refresh();
}
}
function createSpreadAndDesigner() {
const demoHost = document.getElementById('demo-host');
if (window !== top) {
return {
spread: new GC.Spread.Sheets.Workbook(demoHost, { sheetCount: 1 }),
}
} else {
const designer = new GC.Spread.Sheets.Designer.Designer(demoHost, undefined, undefined, { sheetCount: 1 });
return {
designer,
spread: designer.getWorkbook(),
}
}
