Error using FindText with Spire.PDF

[javierfs]

I have a problem when I try this code.

Code: Select all

Dim result As PdfTextFind() = Nothing
result = doc.Pages.Item(i).FindText("Serie").Finds

This return an error.
When I have a pdf without changes it works, but when I try with the same pdf which I replace a image and save it fails.

Code: Select all

Dim page As PdfPageBase = doc.Pages(i)
fls = New FileStream(filename, FileMode.Open, FileAccess.Read)
image = PdfImage.FromStream(fls)
fls.Close()
page.ReplaceImage(cantidadFirmas(_folderOrigen & "\" & filePdf) + 1, image)
doc.SaveToFile(_folderOrigen & "\" & filePdf, FileFormat.PDF)

Can you help me?
Thanks.
Best Regards.

This is the Error Message:

System.FormatException:
{"La cadena de entrada no tiene el formato correcto."} ({ "The input string does not have the correct format."})

StackTrace:
en System.Number.ParseSingle(String value, NumberStyles options, NumberFormatInfo numfmt)

en Spire.Pdf.PdfPageBase.ᜄ(String[] A_0)

en Spire.Pdf.PdfPageBase.FindText(String searchPatternText)

This only happens when the documents have been save or modify one time.
