QUESTION
I am trying to download a large number images from their url(s) and then creating a PDF file out of them in Node.js. I'm using the image-downloader module to download the images in a promise chain and then once all promises are resolved, using another module, images-to-pdf, to trigger the creation of the pdf.
The problem is that most of the promises get resolved immediately in around 5-6 seconds, but there are a few images that are taking quite a bit of time to download. I'd like to force trigger the PDF creation after a certain interval of waiting. Can that be done?
Here is the code

to add a timeout to each images promise and if you're going to resolve it, then you need to resolve it with some sentinel value (I use null
here in this example) that you can test for so you know to skip it when processing the results.

I have a System.Net.Mail.MailMessage which shall have it's html body and pdf attachments converted into one single pdf.

For example, this will throw no error but the resulting pdf will only contain the attachments but not the html email body:

Looks like the HTMLWorker is closing the documents stream right after parsing. So as a workaround, you could create a pdf from your mailbody in memory. And then add this one together with the attachment to your final pdf.
Here is some code, that should do the trick:
