10.2. LaTeX’s device-dependent graphics support

Since the introduction of LaTeX2ε in 1994, LaTeX has offered a uniform syntax for including every kind of graphics file that can be handled by the different drivers. In addition, all kinds of graphic operations (such as resizing and rotating) as well as color support are available.

These features are not part of the LaTeX2ε kernel, but rather are loaded by the standard, fully supported color, graphics, and graphicx extension packages. As the TeX program does not have any direct methods for graphic manipulation, the packages have to rely on features supplied by the “driver” used to print the dvi file. Unfortunately, not all drivers support the same features, and even the internal method of accessing these extensions varies among drivers. Consequently, all of these packages take options such as dvips to specify which external driver is being used. Through this method, unavoidable device-dependent information is localized in a single place, the preamble of the document.
