In 1975, Peter Karow invented a software program for the company Gunold in Stockstadt, Germany, that made automatic stitching of embroidered text possible worldwide for the first time.
In 1970, Xerox put into operation the first small laser printer, and three years later the first PC was developed with a graphical user interface that used a bitmap memory for the creation of the video signal.
Peter Karow realized very quickly that - in the case of coarse resolutions -the mere calculation of bitmaps led to images of letters that appeared distorted through random rasterization.
[6] Initially, the graphical user interfaces on monitors were black and white, and consequently the display of small type sizes was very poor due to jagged edges.
Hot metal typesetting in earlier times used the so-called optical scaling, when fonts were cut bolder and wider with decreasing point size.
The Japanese company Fujitsu hired Peter Karow and Jürgen Willrodt from Hamburg to develop a method that would automatically break down Kanji characters into single elements.
[11] In 1992, Peter Karow developed the Hz-program,[12] the automation of the paragraph justification, together with the well-known typographer Hermann Zapf and Margret Albrecht.
On behalf of the company AdVision digital GmbH in Hamburg, Peter Karow developed the AdCyclopedia, a database for current and historic ads in newspapers, magazines, TV, internet, billboards, movies and emails.
In 1999, the GWA headquarters (German Association of Communication Agencies) entered into a cooperation with the company AdVision digital GmbH in order to provide its members and their customers with an effective competitor monitoring tool on the internet.
