Does the SetOrigin can be used before extracting text, or is it just useful before writing text?
I read text, and want to get coordinates relative to TopLeft.
Seems that SetOrigin does not have effect when retrieving coordinates
Can someone confirm (or not)
Thanks in advance

Hi Eric!
SetOrigin has no affect regarding textextraction
and there's no need to 'cause you can use the
options 3 and 4 to get the position data. So you
know where's your extracted data from. The first
row at the top is always the one with the highest
value (in pixel / psunits). So row number 125 (for
example) is pretty below and 852 is the highest
while using format DIN A4.
Cheers, Ingo

Ingo,
Thanks for your reply, which confirms my thought.
I currently used option3 and it seems that origin is bottom right, regarding position i retrieved and text place in the file.
Does it mean i have to call getorigin before to be sure how the document origin was set? or is text extraction still referring to bottom right?
Thanks again
Cheers
Eric

Hi Eric!
Testextraction from pdf means last in - first out.
So you'll get the last line at first. Page by page.
If the whole page is written in pdf and at the end
the author inserts one word in the first line this word
was the last which was inserted but it's the first
which will be extracted 'cause it's the last content on the page.
With the coordinates you have to rearrange the content...
Cheers, Ingo
