-----------------------------------------
Hi [~tilman],
Thank You.
We are using Apache Tika for Text Extraction and I was able to apply to pass
this value to PDFBox through Tika Configuration and it helped.
I see in Apache Tika code a comments like this:
{code:java}
// True if we should sort text tokens by position
// (necessary for some PDFs, but messes up other PDFs):
@Field
private boolean sortByPosition = false;
...
/**
* If true, sort text tokens by their x/y position
* before extracting text. This may be necessary for
* some PDFs (if the text tokens are not rendered "in
* order"), while for other PDFs it can produce the
* wrong result (for example if there are 2 columns,
* the text will be interleaved). Default is false.
*/
public void setSortByPosition(boolean sortByPosition) {
this.sortByPosition = sortByPosition;
}
{code}
Setting sortByPosition to true fixes this particular problem, but we have a
very large number of various *.pdf documents.
[~tilman], please, advise based on Your experience what value is less risky for
*sortByPosition* option.
Thank You in advance!
Best Regards,
