Created PDF from folder dont't follow images

[DigitLib]

There are 6 xml and jpg named 01...06
Created PDF don't follow this but goes random, e.g.
Page 1 -> 04.jpg
Page 2 -> 03.jpg
Page 3 -> 01.jpg
Page 4 -> 06.jpg
Page 5 -> 02.jpg
Page 6 -> 05.jpg

Is there any convention how to name files?

Thank you!

The tool processes the PAGE XML files of a directory without sorting the directory entries. Try ls -U to get the unsorted list of directory entries. So the page order in the PDF is not random, but can be unexpected. This happens especially if the PAGE XML were not created in a sorted order, for example when running parallel OCR processes.

I used a trick to get sorted entries. Run these commands in the directory with the (unsorted) PAGE XML files:

mkdir sorted
cd sorted
ln -s ../*.xml .

Then use the newly created directory sorted instead of the unsorted directory.

Of course it would be much better to fix the code and sort the directory entries there.
