Hi,


The following code:

PdfDocument doc = new PdfDocument("C:\\temp\\TestA.pdf");
doc.Save("C:\\temp\\TestAafter.pdf");

Thows this error on Save: An fill-in form field must have a Name.
This is the callstack:

at EO.Pdf.PdfField.a()
at EO.Pdf.PdfOnOffField.a()
at EO.Pdf.PdfCheckBoxField.a()
at EO.Pdf.PdfField.a()
at EO.Pdf.Internal.j8.a()
at EO.Pdf.Internal.i0.a()
at EO.Pdf.PdfDocument.a()
at EO.Pdf.PdfDocument.Save(String fileName)

If I modify the code like this:

PdfDocument doc = new PdfDocument("C:\\temp\\TestA.pdf");

foreach (PdfField field in doc.Fields)
{
field.Color = new PdfColor(System.Drawing.Color.Pink);
}

doc.Save("C:\\temp\\TestAafter.pdf");

I get this error on save: Property 'Rect' can not be empty.
The stacktrace is this:
at EO.Pdf.Internal.ai.a[a](String A_0, Boolean A_1)
at EO.Pdf.Drawing.PdfRectangle.a(ai A_0, String A_1, Boolean A_2)
at EO.Pdf.Internal.m6.d()
at EO.Pdf.Internal.m6.h()
at EO.Pdf.PdfField.b()
at EO.Pdf.PdfField.c()
at EO.Pdf.Internal.j8.b()
at EO.Pdf.PdfDocument.a()
at EO.Pdf.PdfDocument.Save(String fileName)

Any ideas ?

Im using EO.pdf version 5.0.34.2. If you need the pdf file for debugging just contact me om my email an i will send it to you.

Hi,

We have posted a new build that fixed the "An fill-in form field must have a Name." error. Please see your private message for the download location.

As to the "Property 'Rect' can not be empty", you will need to change your code like this:



Note that you have to check whether the field is a "terminal" field first because fields in a PDF file can be organized as a tree. You can only set Color on the "terminal" fields.

Hope this helps. Please feel free to let us know if there is anything else.

Thanks!
