PDF Fields Overlay - Input Not Displayed Properly

Good Morning,

I am having some good luck using your products to
perform the following actions in C#:

1. Convert Word documents to
2. Copy form fields from different PDF onto the new PDF, saved
as a different file.

The problem I’ve run into is that when I
open the new PDF with the overlayed form fields and type characters in,
all of the characters bunch up in the first space on top of each other after exiting the fields.

Here is the code I’m using for the conversion:

var asposeFile = new Aspose.Words.Document(path,
Aspose.Words.LoadFormat.Docx, string.Empty);

asposeFile.Save(strSavePath, Aspose.Words.SaveFormat.Pdf);

And here is the code I’m using for the overlay:

var formEditor = new Aspose.Pdf.Kit.FormEditor(oldPdfFile, pdfNew);

Aspose.Pdf.Kit.Form pdfForm = new Aspose.Pdf.Kit.Form(pdfBase);

foreach (string fieldName in pdfForm.FieldNames) {

if (pdfForm.GetFieldType(fieldName) !=
Aspose.Pdf.Kit.FieldType.Radio) {

formEditor.CopyOuterField(pdfBase, fieldName);





My primary coding source for this has been this post:

I've also attached the original document, converted PDF, base PDF, and the End Result pdf for you.

I am so close to having this automated, if this issue can be corrected I will be done.

Thanks a lot for any help you can give me,

Thanks for your request. As I can see part of proccesing which is related to Aspose.Words works fine. So, I will move this request to Aspose.Pdf.Kit forum. My colleagues will answer you shortly.

Best regards,

Update: I have not been able to rectify the issue of letters jumbling on top of themselves in the form fields, and I noticed that the gentlemen posting in the topic referenced in my initial post also observed the same behavior.

Also, CopyOuterFields is incapable of copying radio buttons, and the documentation indicates this as so. Is there any way to add a radio button via a workaround? I tried the following with no results:

if (pdfForm.GetFieldType(fieldName) != Aspose.Pdf.Kit.FieldType.Radio) {
formEditor.CopyOuterField(pdfBase, fieldName);
else {
//get field type
Aspose.Pdf.Kit.FieldType myType = pdfForm.GetFieldType(fieldName);
//get field value
String myValue = pdfForm.GetField(fieldName);
//get field appearance
Aspose.Pdf.Kit.FormFieldFacade myFacade = pdfForm.GetFieldFacade(fieldName);
fieldName, myFacade.PageNumber, myFacade.Box.Left,
myFacade.Box.Bottom, myFacade.Box.Left + myFacade.Box.Width,
myFacade.Box.Bottom + myFacade.Box.Height);

When a radio button is found, the ‘else’ block is executed. The AddField method then throws the error “An error has occurred: Need at least one option, please call FormEditor.setOptions(String[]).: v4.9.0.0”. I do not see this member within FormEditor, so I don’t know what the error means or how to resolve it.

Please advise,
