Abstract

An apparatus for producing dot-matrix data from outline data defining an original outline of an image in an X-Y coordinate system, including a first transforming device transforming, according to transformation data, first interval data defining original intervals regarding the X and/or Y axis, into second interval data defining transformed intervals; a correcting device correcting the second interval data into third interval data defining corrected intervals; a determining device determining, based on the first and third interval data, a transformation function for each of at least one original interval; a second transforming device transforming original or first outline data into second outline data defining a transformed outline, the first outline data including original sets of x and y coordinates defining the original outline, the second outline data including transformed sets of x and y coordinates defining the transformed outline, the second transforming device transforming the x and/or y coordinate of at least one original set of x and y coordinates within each of at least one original interval, into the x and/or y coordinate of at least one transformed set of x and y coord…
