When setting a radio selection via code it appears to change the size of the checkmark to be very small. (Ends up in the top right corner in this example).
The checkmark appears correctly when opening in a reader from the original file or if the file is saved unmodified from Aspose.
See the first gender radios inputs in the attached files
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(@"c:\temp\Test.pdf"); doc.Save(@"c:\temp\preresult.pdf"); // Radio checkmark continues to look correct var field = (Aspose.Pdf.Forms.RadioButtonOptionField)doc.Form.Fields.FirstOrDefault(f => f.FullName == "GENDER"); var radioGroup = (Aspose.Pdf.Forms.RadioButtonField)field.Parent; radioGroup.Selected = 1; doc.Save(@"c:\temp\result.pdf"); // Radio checkmark is tiny
