 Posted: Sun May 25, 2003 2:22 pm Post subject: Can I paste latex equations directly into formula fields? |
 |
|
I use latex on unix/linux all the time for publications. I have used MS PowerPoint in the past for presentations and converted latex equations with TexPoint (very nice!) but have now fully jettisoned MS in favor of linux and for presentations would like to use OpenOffice Impress (or StarOffice--by the way, is there any difference or advantage to using StarOffice?).
However, Impress's OO Math does not seem to use the same language as latex. I really would like to paste my latex formulas directly into Impress. Is there any way to configure Impress to allow this? If not, is there an add-on program (analogous to TexPoint) which will alow me to do this?
Thank you for your help/comments! |

I too have the same problem. It seems tragic that Impress supposed to be specially for us linux users is worse than powerpoint for using latex with it! Does anyone out there know the solution? Or do you all write latex slides from scratch without using open office at all?
Thanks! |

That is a matter of history. Do not forget that the origins of OpenOffice/Staroffice are as a proprietary application that wanted to compete on the desktop market just like any other proprietary office suite. Now Sun, who bought StarOffice from German based "Star Division" (hope I got this name correct) still wants to compete obviously, but to do so switched to a radically different model, that presumably *is* making a difference. If open source developpers were to design it from scratch, they presumably would have choosen to have Math talk Latex. Youĺl have to wait and see if some nice developpers start to create some Math compatible "texpoint" (TexMath"?). What also could help is that you file issue requests on www.openoffice.org.

Staroffice is the "shrink-wrapped" commercial implementation of OOo. It is based on OOo with proprietary extensions. In core functionality, they are fully equivalent (pretty much the same programs because based on the same code). StarOffice has the 'official ' support from the vendor, but you may find that the free support is'n always that bad either  Staroffice is quite a lot cheaper than other suites, and for roll-outs in companies, I would definitely recommend Staroffice. As a private user, you may like the extra's such as clip art and templates or the database component that comes with Staroffice. It comes as CD's nicely wrapped in a box and probably with a printed manual to get you started, but in terms of core Office productivity in Writer, Calc, Impress, Draw or Calc, you are perfectly equally armed with OOo than with Staroffice. |

ftack is it correct to say that OOo's API and UNO components are better than in Starbasic?
I know that there is no big difference, but I think developers improved these components for OOo by adding new features to it and fixing bugs, didn't they?

| Sorry, Cybb20, I can't help you in this as I am not a developper myself and I have yet to write my first OOo macro - recording is the furthest I ever ventured). There are however amazing macro and API experts wandering this forum and they will be much better placed to comment on your question. |

I made a small program (called eqe) to do just that: write the formula in LaTeX, click a button, and just drag the image to Impress (or anywhere else). You can find it at http://rlehy.free.fr .

well ...
eqe could become an openoffice component and thus solve the problem alltogether
think about it |

After a while (I had to install the perl modules + the gtk2-perl, which takes some time to figure out), eqe was up and running. It is a VERY GOOD way of putting LaTeX equations into Impress!
I agree: at some point, OpenOffice should switch from the underachieving equation editor they have to some implementation of eqe, or at least provide the option (in a smooth way!).
Thanks, Ronan!!! |

After some search on Google (not easy, though) I found this macro to write Latex in OpenOffice. Tried it and works!
OOOLatexMacro
http://www.fyma.ucl.ac.be/wiki/~piroux/OOo+macro
It would be fine if it became official... |

Here'a a somewhat elaborate Makefile snippet to create png files of LaTeX formulas that are properly antialiased:
| Code: |
%.svg: %.tex
latex $<
dvips -q -f -E -D 600 -y 5000 -o $*.eps $*.dvi
pstoedit -f sk -dt -ssp $*.eps $*.sk
LANG=C skconvert $*.sk $@
rm -f $*.eps $*.sk
%.png: %.svg
inkscape -e $@ -y 0.0 -d 200 $<
|
Usage
Make a LaTeX file with a formula, e.g. equation.tex:
| Code: |
\documentclass{minimal}
\begin{document}
\begin{displaymath}
\int f(x) dx
\end{displaymath}
\end{document}
|
then type
$ make equation.png
and insert that equation per drag'n'drop into Your presentation. Now make the formula png half the size and it should produce a nicely antialiased formula. If You link the png You can edit the tex file and rerun `make' without further steps, the new formula will then be present in Your presentation after a reload. Resizing to a smaller image in Impress is necessary for proper antialiasing, I was not satisfied with formula images that already had the final presentation size.
This code snippet converts the eps to svg and then to png via Inkscape. You need to have LaTeX, pstoedit, skconvert and Inkscape installed.
I like to keep my formulae in separate LaTeX files for editing with my favourite editor rather than editing them inline in some other program, but I was to lazy to adjust the tex2im script mentioned above with this code...
Pros:
- uses antialiased png formulae with transparent background, makes the presentation portable
- can render anything LaTeX produces, even weird/rare mathematical symbols (at least I think so)
Cons:
- each inserted formula needs a manual resize step once
- needs some additional tools to be installed
Hope someone finds it useful though  |

nice idea. But I get errors. Any idea what happened?
I downloaded the tools today.

| Posted: Tue Nov 06, 2007 9:58 am Post subject: Easier creation of LaTeX .png files with Inkscape |
|
|
I must confess I stole the last snippet I posted earlier from a colleague. Meanwhile I found out that Inkcsape is able to create a nicely antialiased .png directly from the .eps file:
| Code: |
$ inkscape -e equation.png -i svg2 -d 200 equation.eps
|
The option `-i svg2' helps Inkscape exporting the relevant area of the visible formula (i.e. the bounding box of the .eps). This method also preserves the shape of the LaTeX letters, while pstoedit distorted them slightly.
With
| Code: |
$ inkscape -l equation.svg equation.eps
|
one could convert the .eps into a plain .svg file directly, but as long as .svg import is not readily available in OOo, I am afraid one has to resort to this workaround with .png files...
The resizing of the imported .png in OOoImpress has still to be done as explained in my last posting.
Still buggy 
I just encountered that in this solution Inkscape has problems with fraction bars in formulae (does not recognize it in the eps file). Converting the formula with pstoedit into .sk format does the job...
*#$%, why has it be so hard to get .eps into another vector format?  |
