Size of OCRd text

[charuvasudev]

Hi,

I have used PDFXchange and tesseract for OCR in my project. And it works fine. My only concern is that the font size of the OCRd text which is added in the text layer of the pdf file is too small. When I do Ctrl+F and search for a key word, it highlights the text. The highlight is so small that it appears like a dot which is easily missed. Shouldn't the font size be automatcally calculated? It works as expected in your end user control. see the attached image for more clarity.

Here is the code-

Dim Op As PDFXEdit.IOperation = Inst1.CreateOp(nID)
Dim input As PDFXEdit.ICabNode = Op.Params.Root("Input")
Dim fsInst As PDFXEdit.IAFS_Inst = CType(Inst1.GetExtension("AFS"), PDFXEdit.IAFS_Inst)
Dim impPath As PDFXEdit.IAFS_Name = fsInst.DefaultFileSys.StringToName(OpenFileDialog1.FileName)
Dim stroutputpath As String = System.IO.Path.GetDirectoryName(OpenFileDialog1.FileName) & "\" & System.IO.Path.GetFileNameWithoutExtension(OpenFileDialog1.FileName) & DateTime.Now.ToString("MMddyyymmss") & ".pdf"
Dim fsInst1 As PDFXEdit.IAFS_Inst = CType(Inst1.GetExtension("AFS"), PDFXEdit.IAFS_Inst)
Dim outPath As PDFXEdit.IAFS_Name = fsInst1.DefaultFileSys.StringToName(stroutputpath)
Dim pxcInst As PDFXEdit.IPXC_Inst = CType(Inst1.GetExtension("PXC"), PDFXEdit.IPXC_Inst)
Dim resDoc As PDFXEdit.IPXC_Document = pxcInst.OpenDocumentFrom(impPath, Nothing)
input.v = resDoc
Dim options As PDFXEdit.ICabNode = Op.Params.Root("Options")
options("OutputType").v = 0
options("OCRNoTextPagesOnly").v = True
Try
Op.Do()
Catch ex As Exception
resDoc.Close()
Exit Sub
End Try
resDoc.WriteTo(outPath)
resDoc.Close()


Pls guide.

Hi,

Any update on my issue?

Hello, charuvasudev

You posted this during the holidays, we have a bit of a backlog, but the Dev team is working through things. I cannot promise when they will be able to respond, but we will be back to you once they have taken a look.

Kind regards,

Hi, charuvasudev.

Maybe the difference is because the Editor EU uses the newer "op.document.OCRPages2" operation internally, instead of the much older and now-obsolete "op.document.OCRPages", which you use. I recommend starting to use the new version with the "SkipPagesWithText" parameter, as equivalent of "OCRNoTextPagesOnly" from the older version.

HTH.
