Abstract: Изобретение относится к способам визуализации текстовой информации на экране. Его применение позволяет получить технический результат в виде обеспечения автоматического размещения типографских деталей на границах высокого контраста подкомпонентов элементов изображения, экономии времени обработки и ресурсов. Указанный результат достигается посредством выполнения частичного, а не полного топологического анализа символа. Так как установлено, что в устройствах отображения, имеющих вертикальные полосы подкомпонентов элементов изображения одного и того же цвета, удобочитаемость символа увеличивается, когда левые края ножек выровнены с границами высокого контраста между подкомпонентами элементов изображения, то способ содержит операции, направленные на достижение этого. 5 н. и 35 з.п. ф-лы, 8 ил.
