Set background image to each page of survey

Hello Jane
I want to set different image on each page in pdf file
The link you added is not working getting error

Hello,
Please accept my apologies for sharing a wrong link. You can access the demo at Add a Background Image to a PDF Form.

If you wish to render the same image on individual survey pages, you can follow this demo and use the surveyPDF.onRenderHeader function. Please try this demo: View Plunker.

JavaScript
 surveyPDF.onRenderHeader.add(async function (_, canvas) {
        await canvas.drawImage({
            base64: image, // A Base64 encoded image
            rect: {
                xLeft: 0,
                xRight: canvas.controller.paperWidth,
                yTop: 0,
                yBot: canvas.controller.paperHeight,
            }
        }).then(() => {
            canvas.packs.unshift(canvas.packs.pop());
        });
});

Let me know if this code works for you.

Hello jane

Here is any way to set different image on each page?
Like image1.png on page 1
image2.png on page2 and so on…

Hi,
If you wish to render an individual image on each survey page, modify the canvas.drawImage function and render an image on a rectangle with the yBot: canvas.controller.paperHeight parameter.

JavaScript
surveyPDF.onRenderHeader.add(async function (sender, canvas) {
        await canvas.drawImage({
            base64: image,
            rect: {
                xLeft: 0,
                xRight: canvas.controller.paperWidth,
                yTop: 0,
                yBot: canvas.controller.paperHeight,
            }
        }).then(() => {
            canvas.packs.unshift(canvas.packs.pop());
        });
});

Take note that page background images will appear as expected only if the resultant PDF contains the same number of pages as the original survey has. If a PDF document contains a greater number of pages because survey questions take more space, the page background image may not appear as expected.

Please let me know if you have any further questions.

Hello Jane
