---------------------------------------
Hi Tilman,
Well, although I recognise what you mention about proportional fonts I can't
agree it isn't possible. I found a product named A-PDF. They offer three types
of PDF to text conversion with a free product and one of these options does
what I was looking for, it fills blank areas with spaces. I think another good
method could be to insert a tab character instead of spaces. That would
eliminate the math needed to fill blank areas with spaces where a proportional
font is used. So, I think, when an option was added to Tika to replace x
spaces with a tab character the problem would probably be solved. Can you agree
yhat could be a solution?
Kind regards,
Rens Huizenga

> I have to convert Pdf's to database data. I developed a parser that reads
> .txt files. The original data is available in PDFs only . Therefore .txt
> files will have to be created by Tika converting the PDF's to .txt. After
> conversion I recognise an alignment issue with the .txt data compared to the
> columns in the PDF. On the TIKA website I read that I need to check if the
> problems also occurs in PDFBox, so I checked for that. PDFBox has the same
> issue.
> These lines of PDF data:
> a b c d e
> a b c d e
> are both presented as
> a b c d e
> in the text file, causing for example numbers to be presented in the wrong
> "column".
> Unfortunately I cannot share busniess documents, but i have created an
> example in Excel, saved it as PDF and converted it to .txt. See attachments.
> In addition I converted the testset online with Convertio.co. Their results
> is as expected, with enough spaces between the words/numbers to recognise the
> column.
