MultiLine Line Spacing broken from v17.3.0

The line spacing in multiline fields is broken on some of our form fields if we use a version of Aspose.PDF after v17.2.0. I assume this is related to change PDFNET-42024, “Line Spacing Increased on Multiline Textbox”. This is still broken in Aspose.PDF v19.6.0.

Acrobat Reader handles the form field correctly.

TextField.pdf (3.1 KB)

namespace AsposePlayground
    using System.Linq;
    class Program
        static void Main(string[] args)
            var pdfLicense = new Aspose.Pdf.License();

            var form = new Aspose.Pdf.Facades.Form("TextField.pdf");

            form.FillField("TextField", string.Concat(Enumerable.Repeat($"abcdefghijklmnopqrstuvwxyz\n", 5)));

We’re using v22…11.0. We’re still seeing this behavior with multi-line spacing. This seems like a bug that you introduced years ago. Is there a fix for this yet? If not, what will paying for more support actually do here? Why not just fix this issue or post the workaround in this forum?

This issue may very well cause us to ask for a refund and find a different product, unless we can find a fix for this.


We apologize for the inconvenience faced due to this bug. Your concerns have been recorded and the issue has been escalated to the next level of the priority.
