Due to that the code block [Note 1] that creates a too large pdf (input 2 MB; output 80 MB), you have created a track id as : PDFNEWNET-30669. Do you have any other approach to replace a text with regex of "[0-9.]*[A-Z.]*[a-z.]*[ ]*Page [0-9]+ of [0-9]+"? Because we can not wait too long. I tried another approach [Note 2], it won't work and you created another track id as PDFNEWNET-30674.
The problem is that if output pdf is too large, the code [Note 1] can not be executed repeatedly. System got "OutOfMemory" error. And strange thing is that system needs to "wait" for a while (10 - 20 minutes) to let [Note 1] run successfully again. As analysis goes, a small pdf created by Aspose works fine so far for LBB, but a large one.
My system is Intel(R) Core(TM)2 Duo CPU E8400 3.00GHz RAM 4GB Visual Studio 2008 Framwork 3.5.
Do you have another code that replace a text in pdf without creating a too large pdf?
Dim contentEditor As New Aspose.Pdf.Facades.PdfContentEditor()
contentEditor.ReplaceTextStrategy.IsRegularExpressionUsed = True
contentEditor.ReplaceTextStrategy.ReplaceScope = Aspose.Pdf.Facades.ReplaceTextStrategy.Scope.REPLACE_ALL
contentEditor.ReplaceText("[0-9.]*[A-Z.]*[a-z.]*[ ]*Page [0-9]+ of [0-9]+", String.Empty)
Dim pdfDocument As New Document(outPutFile)
Dim textFragmentAbsorber As New TextFragmentAbsorber("[0-9.]*[A-Z.]*[a-z.]*[ ]*Page [0-9]+ of [0-9]+")
Dim textSearchOptions As New TextSearchOptions(True)
textFragmentAbsorber.TextSearchOptions = textSearchOptions
Dim textFragmentCollection As TextFragmentCollection = textFragmentAbsorber.TextFragments
For Each textFragment As TextFragment In textFragmentCollection
textFragment.Text = String.Empty
