RE: [xep-support] Table Border thickness in PDF

I am looking at the PDF you provided. I am not seeing a problem with the
rendered lines, nothing blatant anyhow. I see very subtle differences, and
using two different PDF viewers I see very very slight variations, but
zooming in and out these variations go away. I believe this is nothing more
than a screen resolution / screen redraw issue, but ultimately a problem
with the PDF reader itself.
Perhaps you can provide screen shots of the variations you are seeing.

Subject: [xep-support] Table Border thickness in PDF


attached you find a FO file and a PDF I generated with it. If the attachment
doesn't come through: The FO file consists of a table with 8 rows, each row
with a different height. Each cell has a 1pt border at the top.
Like this:

<fo:table-row height="18pt">
  <fo:table-cell border-top="solid 1pt #3366FF">

The problem with the PDF is that the line thickness of the table borders
changes to different sizes per row when viewed with Adobe Reader 8. It's
mostly ok in fullscreen mode (131% in my case) but when displayed in 100%,
the lines have a different thickness: Some are 2, some are 3 pixels thick. I
guess that has to do with the internal rasterization algorithm of Adobe
Reader, but I would like to know if there is any way around this effect
because the PDF files I want to produce are mainly to be shown on screens.
FYI, When I turn vector antialiasing on, the lines look a bit better, but
have a "smeared" look.

If I create PDFs with tables with InDesign I get much better results - I
guess the problem is not the sole fault of Adobe Reader so there should be a
way to do it.

Any suggestions?
