IguanaTex is a PowerPoint add-in which allows you to insert LaTeX equations into your PowerPoint presentation. It is distributed completely for free, along with its source code.
If you know how to use LaTeX, it is very easy to use IguanaTex. Select New LaTeX display from the IguanaTex tab of the ribbon, and you will get a dialog box where you can type your equation:
Type any valid LaTeX code, and click on Generate. IguanaTex will compile your code into LaTeX, generate an image from it and insert it into PowerPoint.
Need to change something in the equation? Just select the image, then click on Edit LaTeX display in the IguanaTex tab of the ribbon, and the IguanaTex dialog will re-appear so you can edit the LaTeX code.
Generated bitmap displays are ordinary PowerPoint images, and vector displays are PowerPoint shapes. They can be grouped, animated, rotated, moved, resized, etc. Further editing of the equation will preserve all these changes.
To make similar changes to multiple displays (e.g., changing LaTeX engine, size, DPI, vector/bitmap, transparency, and simple text search & replace), select multiple displays or even multiple slides, and use "Regenerate selection" to apply all changes at once.
Both the image and LaTeX code are saved with the presentation: you can display your presentation on any computer, even those without IguanaTex. Of course, equations can only be edited if you install IguanaTex.
Former TexPoint users, rejoice: you can now edit with IguanaTex (v1.40+) your TexPoint displays, which will be automatically converted to IguanaTex format. You can either edit a TexPoint display as a normal IguanaTex one as described above, or just select one or more TexPoint displays (or the slides that contain them) and click on "Regenerate selection" to convert them to IguanaTex format.
