Slow performance of facades FillField method

Aspose.PDF Product Family
#1

The facades FillField method is running very slow for one of my pdf forms. Most other run quickly. I have a sample program that illustrates the problem by comparing the slow form to a fast form.Can you take a look and tell me how I can speed up my slow form?

Code:

FileStream fs = new FileStream(sourceName, FileMode.Open, FileAccess.ReadWrite);
//open document
Aspose.Pdf.Facades.Form form = new Aspose.Pdf.Facades.Form(fs);

        int currentField = 0;

        foreach (string formFieldName in form.FieldNames)
        {
            Aspose.Pdf.Facades.FieldType fieldType = form.GetFieldType(formFieldName);

            if (fieldType == Aspose.Pdf.Facades.FieldType.Text)
            {
                form.FillField(formFieldName, currentField++.ToString());
                System.Diagnostics.Debug.WriteLine("{0} Field {1}", stopwatch.ElapsedMilliseconds, formFieldName);
            }

            if (currentField >= 20)
                break;

        }

        System.Diagnostics.Debug.WriteLine("20 fields loaded in {0}", stopwatch.ElapsedMilliseconds);
        form.Save(targetName);
        fs.Close();

I can upload the .NET solution if there is a way to do that.

@IFSTim,
We have tested your code for a sample PDF document with the latest version 17.8 of Aspose.Pdf for .NET API and it takes 1.5 seconds to fill 20 fields. Kindly send us your source PDF and also let us know which Aspose.Pdf for .NET API version you are using. We will investigate and share our findings with you. Your response is awaited.

Here is the pdf form that is slow to load. I do see other forms load quickly so I’m wondering what is different about this form and is there a faster way to load it?
