Tilman Hausherr updated PDFBOX-3970:
------------------------------------
Attachment: LegacyPDFStreamEngine.java
It looked good at first but when I tried to run it on the file from PDFBOX-4000
I got some weird effects... ("N" and "o" had almost the same visual bounds) one
problem in your code is that you're using the height, instead of using the
upper Y coordinate. I then removed the translation because we need the shapes
from the baseline and don't care about the rendering position on the page (this
is done later in the code). I am attaching my current code. Make a diff to
yours to see what it is about. It is a bit messy. I see you changed the type3
code at the bottom, I didn't investigate that, I'm using the existing type3
code.
I then ran the tests and got many regressions. Some can be explained (e.g.
PDFBOX-3062-002207-p1.pdf), but at least one is weird, the sorted result of
PDFBOX-2984-page180°.pdf.

> Hello Support Team,
> I am working on a project which parses a whole PDF document and stores the
> extracted text in some .txt file which can be read by other product.
> My issue is regarding extracting the text inside the cell of a table:
> *x,y co-ordinates of the text inside the cell are not getting correctly.*
> Y value of the last text line in the cell is getting larger than cell's max-Y
> value.
> I have attached the test file with this bug.
> As you can see in the test document, there is one cell along-with text in it
> and a text paragraph next to that cell.
> x-y coordinates that I get from pdfbox for all the paths (two vertical and
> two horizontal lines) of the cell are:
> (in x1,y1,x2,y2 format)
> Horizontal line 1: [100,88,220,88]
> Horizontal line 2: [100,120,220,120]
> Vertical line 1 : [100,88,100,120]
> Vertical line 2: [220,88,220,120]
> (Y values of the above paths are final values by subtracting the actual value
> given by pdfbox from height of the page as I see that for paths, y-values are
> processed from bottom to up)
> And bounding box of the last line in that cell is : [102,114,59,7] and hence
> max-Y of that line becomes 121 (min-Y + height)
>
> So, if we consider max-Y value of that cell (i.e. 120) and that of last line
> in that cell (i.e. 121), clearly, that line goes out of that cell.
> What can be the possible reason for this?
> Thank you in advance!
> Regards,
> Navnath Kumbhar
