I am using the beamerposter.sty file to make my poster and I want to put a background in the title section of the poster- not a graphic or logo of an institution, but an actual background that spans the entire length of the poster title.

I have been searching but I can't seem to find anything that specifically addresses this issue. I have the eso-pic, background, and wallpaper packages so if you can provide a solution with any of those I'd be grateful. Here is an example of what I mean to accomplish

The poster has a blue background with a shell. I'd like to know how to do this in LaTeX (not necessarily with the same graphic)

Here is the skeleton of my poster

I do not intend on using the provided picture but the idea is identical.

Perhaps you will be satisfied with this solution. I just modified the header definition from the confposter package. I don't know how to determine the real height of the title, so it will be necessary to manually adjust the size of the background picture. Besides, I'm not familiar with tikz package and I assume that there may be a better solution. I used "scope fading" to improve the transition to poster text. It has a side effect: this option reduce the width of the picture. Therefore, I added the parameter "scale=1.01". "fig" is the name of any picture for the header background.

  • Thanks for the quick reply! So I have applied your edit with a placeholder picture of mine and everything compiles with no errors but I do not see the placeholder picture that I am using. It may just be a question of picture size and position. Did you have a file name for 'fig' like 'placeholder.png' or 'placeholder'? – TAO May 24 '18 at 20:03
  • I'm sorry, when I was formatting the text apparently removed some of the options of the environment 'tikzpicture'. The correct title should be '\begin{tikzpicture}[remember picture, overlay]'. I have already corrected this error in my answer. – Vladimir May 24 '18 at 21:17
  • @TO4991, In fact, the file name was 'fig.png'. And pdflatex should find the appropriate file. – Vladimir May 24 '18 at 21:36
