How to Burn In Markup, Producing a New PDF

First, create a PrizmDocServerClient:

var prizmDocServer = new PrizmDocServerClient(/* your connection info */);

Then, call BurnMarkupAsync providing 1) the original document and 2) the markup JSON file which defines the areas to be redacted:

RemoteWorkFile result = await prizmDocServer.BurnMarkupAsync("original.pdf", "markup.json");

This will upload both the original document and markup JSON file to PrizmDoc Server, ask PrizmDoc Server to burn in the markup, producing a new redacted PDF, and then return once the burning process is complete.

The returned result is just metadata about the output; the actual output file has not been downloaded yet. To actually download the result from PrizmDoc Server, call SaveAsync on the returned result:

await result.RemoteWorkFile.SaveAsync("redacted.pdf");

Or, if you'd prefer instead to download the bytes to a stream, call result.RemoteWorkFile.CopyToAsync:

await result.RemoteWorkFile.CopyToAsync(myStream);

Here is a complete example:

using System;
using System.Collections.Generic;
using System.IO;
using System.Threading.Tasks;
using Accusoft.PrizmDocServer;
using Accusoft.PrizmDocServer.Redaction;

namespace Demos
{
    class Program
    {
        static void Main(string[] args)
        {
            MainAsync().GetAwaiter().GetResult();
        }

        static async Task MainAsync()
        {
            var prizmDocServer = new PrizmDocServerClient(/* your connection info */);

            RemoteWorkFile result = await prizmDocServer.BurnMarkupAsync("original.pdf", "markup.json");

            await result.SaveAsync("redacted.pdf");
        }
    }
}

There are additional overloads of BurnMarkupAsync which allow you to use existing RemoteWorkFile instances instead of local file paths. See the PrizmDocServerClient API reference for more information.
