# Combine ipe and beamer presentation (font identification)

I am trying to transition from an existing ipe presentation to beamer by combining slides from both into the same presentation. To do this I need to match the existing slides in beamer, a job that shouldn't be too hard I thought. However, can anyone tell me how to reproduce the following please.

My first problem is the font. Using acroread or pdffonts to determine the fonts used I get a long list that I can't interpret. whatthefont.com gives a few options and the closest is http://www.myfonts.com/fonts/processtype/seravek/extra-light/ which I find hard to believe.

The fonts are the standard Computer Modern Sans. There are other CM fonts, probably because the test.pdf has been extracted from a bigger one. –  egreg Oct 13 '12 at 22:36
Thanks, I should have noticed that. Just need to get it exactly the same in Beamer now. –  Raphael Oct 14 '12 at 9:27

## 1 Answer

The fonts are easy, actually only three of them are used in the page that was extracted from a larger file via pdftk:

• The header was set in CMSS12.
• For the text CMSS10 is used.
• The item bullets come from CMSY10.

The prefixes, seen in the output of pdffonts are typically added for fonts that are not embedded as full fonts, but using a subset of the needed characters.

An example file that shows the font usages.
Edit: Paper layout added and font sizes fixed.
The header font is scaled by a factor of 2.8 and the text font by a factor of 2.4. The example therefore uses \mag=2400 and \Large instead of \large for the header font to get 2.8/2.4 scaling.

\mag=2400
