Add a watermark to second of 3 PDF's

[iii-james]

I am using this post as a reference. I have a pdf that has 3 pages. I only want to merge a watermark on the second one. Is this possible with pdfUtils?

const jsreport = require('jsreport-proxy')

async function afterRender(req, res) {
    const watermarkRes = await jsreport.render({
        template: {
            name: 'Watermark' 
        }   
    })

    const $pdf = await jsreport.pdfUtils.parse(res.content)
    const pagesToMerge = new Array($pdf.pages.length).fill(watermarkRes.content)

    const originalBuffer = Buffer.from(res.content)      
    const withWatermarkBuffer = await jsreport.pdfUtils.merge(originalBuffer, pagesToMerge)
    res.content = await jsreport.pdfUtils.append(res.content, withWatermarkBuffer)
}

You could do this without an extra script.

@admin I actually have another scenario. In the watermark template I need to be able to access the data passed into the parent template. Is that possible?

[admin]

The input data from the original template are forwarded to the rendering of the pdf operation.

@admin thanks for pointing that out. I had to prefix the data with @root because I was inside an iteration.
