Here's what I've just written for UserGuide.lyx: How it works ========= LyX has the ability to handle literally any graphics format in the known universe so long as a conversion path from this graphics format to the target output format can be created. If that sounds a little obtuse, consider how LyX handles Encapsulated PostScript® figures. LaTeX provides native support for this format, so LyX needs do nothing other than use the \includegraphics LaTeX command to insert the figure in the final document. To view the figure on the LyX screen, however, some additional work is required because neither the XForms nor the Qt GUI libraries can load PostScript® figures themselves. The XForms library can load figures in the following, widely used graphics formats: bmp, gif, jpeg, pbm, pgm, ppm, tif and xbm whilst the Qt library can also handle mng, png and xpm format figures. Thus, LyX must initiate a conversion from eps to a loadable graphics format. It does this using the powerful, configurable converters mechanism exposed in the Converters section of the Edit->Preferences dialog. If LyX cannot create a conversion path (which might have many steps) from eps to one of the loadable formats listed above, then it defaults to the use of ImageMagick's convert utility. If, after all that, LyX still cannot load the figure, then it'll tell you so with a message "Error converting to loadable format" in place of an on-screen view of your figure. If you're presented with such a message, then you'll need to augment the list of known converters. This strategy is used both to generate on-screen views of your image and when generating the final document. In the latter case, the LaTeX compiler must be supplied with graphics files in PostScript® format. Similarly the PDFLaTeX compiler requires files in pdf, png or jpeg format. LyX will handle the necessary conversions behind the scenes.
