Discovering beziér curves

In the beginning. PostScript was thought to work in the field of office environments. But nevertheless, the integration of the different page elements played a key role in the concept from the beginning. In the first time it was not possible to use colors, and the greyscale pictures had have an awful resolution too. But now there has been a central page description language for all the elements that a printing page may contain, integrating text (typefaces), pictures (pixel information), as well as graphics (vector elements, beziér curves).

And because film output was possible soon, PostScript established in the field of prepress technology. With increasing version numbers, the technical possibilities increased rapidly too. The parallel running development of Photoshop, PageMaker, Quark etc. allowed on the basis of more and more powerful hardware integrated production of full color pages, integrating all ever existing elements and forms.

Curves are described in PostScript using ***Polynome dritten Grades***, what gives a good description of the curves while using less ***Stützpunkte***. This is the main difference to TrueType typefaces, what is using quadratic splines. Potentially, PostScript typefaces have got a higher quality.
