Re: overlay images in Beamer

[rupai]

Hi,

Thanks for your suggestions.

@Werner
I tried the overprint option but it displays the images on two
separate slides.

@Zio_Pecos
I tried your suggestion also but got the same result.


I have two separate images with different dimension. Image 2 is kind
of a zoom in version of a smaller portion of image 1. The idea is to
display image 1 (bigger image) and then display image 2 on top of it
so that both images are visible at the same time. I also want to
connect the corners of the 2nd image to the smaller region of the 1st
image. Any suggestion?

regards,
rupai

See http://www.tug.org/pracjourn/2007-3/tsyplakov/tsyplakov.pdf and
http://tpx.sourceforge.net/

I am using TpX and it is working well (that is, I am managing to do
what I want to do). I still have to split images over several slides
but I have no trouble with this when it comes to a slideshow
presentation where I'm going to have to "click" to advance the
presentation in any case.

For printing notes, I simply made one complete figure and then used:
\usepackage[handouts,t]{beamer}

\begin{frame}<handout:0>[plain]\frametitle{X}

stuff...

\end{frame}

<handout:0> means the slide is excluded from the notes. <beamer:0>
means the slide is excluded from the presentation. <beamer:0 handout:
0> means the slide is excluded all together... Read

All the best.

It appears to execute under wine-1.2 (in my Ubuntu 10.4)

I would create the image as required in another program such as gimp
or inkscape. Then I would use the the package 'textpos'.

@Peter,
thanks for your reply. I am using an older version of
Ubuntu. I'll give it a try after upgrading the current version.

@r
I created a png file with transparent background in
GIMP. But when I complied my presentation with pdflatex , the image
appeared completely dark in the pdf file. I am not sure if this
problem is specific to my system only. Does anyone encounter similar
problem with transparent png files in Beamer ?

regards,
rupai

Try to change the background to a colour suitable for the
presentation, for example if the presentation is to use black text,
use a white background for the image.

[Werner Grundlingh]

...perhaps try putting the original image in a box of size zero, and
then adding the second image. If the two images have the exact same
configuration and dimension, this should work. For example:

\makebox[l][0pt]{\includegraphics{figure1}}\includegraphics{figure2}
