Good morning
I will continue a little bit my monologue.
I figured out few things.
Concerning the pdfloc coordinates:
<fragment start="#pdfloc(3adc,0,33,0,0,0,0,1)" end="#pdfloc(3adc,0,33,0,3,0,1,1)"/>
-3adc remains the same for this document = probably format information ? (note: i made another document same style and got 370d)
- the 2nd coordinate remains as well the same = might be the page number
- the 3rd coordinate (33) represent the line number = increases every time by 8
--> It is not the number of signs (which I increased every line +1). I made another document with steady characters each line and it is as well increasing +8
- the 4th no idea
- the 5th (0 on the left, 3 on the right) seems to be the number of characters increasing by 1 every line (confirmed with steady numbers in my 2nd document).
I saw as well that the 5th remain 0 on both sides when you only would mark one letter and becomes 1 for 2 letters.
Concerning the other ones I have no clue yet
EDIT: I am not sure whether the system is based on letters or pure coordinates.
So additional information. I made the pdf document with font size 12 which means
for each x we have like 7.5 pixels verticaly and ca. 17 pixels per line of text.
So, probably the factor for each line is like 2x (8 in coordinates represents 17 pixels/2)
