Development of PostScript Procedures for Transformations of Digital Typography

This work presentes the result of researching of digital typography transformations which are based on the development of PostScript procedures. This is development of the designer programmatical modules which has not existed in conventional graphic programs. Program modules combine Em-Square and custom functions while the construction of Em-Squares is programmatical led by Postscript procedures. This paper presentes applied transformational matrices and PostScript code. Procedures are interpreted by PostScript interpreter for the given output resolution so their processing is on fastest possibly speed. Procedures which are prepared in encapsulated format can be integrate with conventional vector graphics. This work gives the contribution to the development of digital typography and typographic design through new native PostScript procedures and new possibilities of designing original typographic solutions.
