Hi Dimitry!
I've only a universal answer... ;-)
The textextraction doesn't extract the textcontent "line by line" (like you read it). The extraction extract first what was insert first. If you have a page where first header and footer was inserted, you'll extract first header and (the end of the page) footer and after this the content from the middle. If you have a text with several columns it's hardly possible to read the text later 'cause first all rows of the first column will be extracted.
On the last two values you can see the start positions (row and column) of each string in pixels. So you can see at the second picture that all strings are in the same pixel-row (366) but the columns are very different. The point isn't directly before the F. He is far away on the left (outside of the picture. Normally you'll extract longer strings but if this point was inserted alone later he'll appears as a single string.
Best regards,
Ingo
