PostScript语言教程与手册 英文

he POST SCRIPT page description language provides a device in-dependent standard for representing the printed page. This book is designed to be a companion piece to the POST SCRIPT Lan-guage Reference Manual. It presents illustrative material to aid in understanding the P OST SCRIPT language. The tutorial infor-mation presented here has been deliberately separated from the reference manual to help ensure that the defining document of-fers a precise, unambiguous definition of the language and asso-ciated graphics imaging model. In all cases, when questions of definition or precise specification are raised, the POST SCRIPT Language Reference Manual is the final word.
