Document Classes ⇒ Beamerposter - Annoying white line on the edge

[achim]

Dear community

I am currently making my second beamerposter. The problem described here also occurred in the first one but I just ignored it. Now I'd like to get this problem out of the way...

Please find the poster attached to this post, so you know what I'm talking about.

Poster.pdf

(243.32 KiB) Downloaded 847 times

The poster attached shows a white line on the left edge. If I compile the document in 'portrait' format, then the line is on the top (covered by the uni crest on the rhs).

This is not too disturbing as long as the poster is in 'landscape' format as it can be cut off, however it looks pretty awful in 'portrait' format.

Did anybody ever come across this problem or has anyone a hint as to where the origin of the problem might be?

Here's the code:

ps: Make sure you provide a picture (instead of Images/CrestWB) if running the code.

Your code generates over 100 errors for me, then quits. You need to construct a properly compiliable minimal working example per board rules. It is impossible to diagnose anything otherwise.

[achim]

You're right, I'm sorry.

OK here is a striped down version of it. It uses the 'Berlin' style sheet. The problem still persists (both in landscape and portrait as described above). Hence my style sheet should be good.

Cheers!

I only see the problem if compiled via latex > dvips > ps2pdf. If I compile with pdflatex directly, I don't see an issue. I gather from your first example, however, that you need to use PSTricks? How difficult would it be to get around this? (Either by switching to Tikz or exporting the individual graphical elements to eps then converting them to pdf and including them?)

Another possibility worth considering might be simply using pdfcrop on the final result... seems to do the trick.

[achim]

Interesting, thanks for pointing that out!

You're right I do work with pstricks (a lot that is). I might have to consider pre compiling the pstricks images to .eps.
The thing is, I'm quite used to pstricks now and do like it very much. Tikz does not look bad either but for now I'd rather stay with pstricks.

I will (as much as time allows) investigate further into why this happens when I compile dvi ps pdf.

Many thanks!
Achim
