Character production on picture or display, e.g. X-ray of patient, comprises using arrangement which determines and stores maximum and minimum print size and side length values, and which calculates print size

摘要

An arrangement for producing characters on e.g. a photograph or display, comprises a device for determining and storing a primary set of values which has a minimum side length and minimum print size, and a secondary set of values with a maximum side length and maximum print size. A second device determines and stores the side length of the picture, and a third device calculates the print size. An arrangement for producing characters on e.g. a photograph or display, comprises a device for determining and storing a primary set of values which has a minimum side length and minimum print size, and a secondary set of values with a maximum side length and maximum print size. A second device determines and stores the side length of the picture, and a third device calculates the print size using the formula; f = ((f2-f1)/(x2-x1)) (xa.yb - x1) + f1 where a and b are used to manually fit the character size to a given picture side ratio (x/y).
