Hello,

I used quick pdf to Extract the text from a pdf file.For Some Pages It Gives the error " scan line Index out of Range".

The Code That i Used is Here Below

Language : VB 6.0

O.S. WIn-2000 Prof.

--------------------------------------------------------
Dim data As New iSED.QuickPDF

FileHandle = data.DAOpenFile(PdfFileName, Key)
PageReference = data.DAFindPage(FileHandle, 1)
ImageListId = data.DAGetPageImageList(FileHandle, PageReference)
ImageListCount = data.DAGetImageListCount(FileHandle, ImageListId)

For idxPageCnt = 1 To data.PageCount
           data.SelectPage (idxPageCnt)
            ' The Below Line It Creates The Error and it does not Read the File content
     sFullPageArr = Split(data.GetPageText(3), Chr$(13), -1, vbTextCompare)
            For i = 0 To UBound(sFullPageArr) - 1
                arrsplit = Split(sFullPageArr(i), ",", -1, vbTextCompare)
                If UBound(arrsplit) > 11 Then
                    For z = 11 To UBound(arrsplit)
                        If arrsplit2 = "" Then
                                arrsplit2 = arrsplit(z)
                        Else
                                arrsplit2 = arrsplit2 & "," & arrsplit(z)
                        End If
                    Next
  end if
     next
Next

Hi!
First you're using the DA-functions and then...
Why you don't use DAExtractPageText instead of GetPageText?
Have a try.

Sir,

Now I used DAExtractPageText().The same Error Comes Here when the option is 3. I also Used Other arguments 1 and 2 as options to DAExtractPageText().

The Function works . But It Returns only 2 co-ordinates. How can i Identify the left,top,right,bottom of a line.

Regards,

Hi Gerald,

you need only two coordinates 'cause you've the font height in pixel and you know the text length...?

Hi Gerald!

Read in the QuickPDF-documentation in the chapter "Fonts".
You can use "FontSize"...

Good luck,
Ingo
