Спасибо. теперь надо что бы линия доходила до внутреннего кольца

но не доходит.

п.с Простите меня за мои познания в геометрии.

И еще можно ли сделать заливку определенного куска не вырисовывая отдельную часть нужного цвета?

Эта линия рисуется от левого верхнего угла рабочей области до правого нижнего + разворот на 23 градуса

Это так сложно вы объясняете, что линия должна быть под углом 68° к горизонтали?

Этот скрипт рисует круг, а на круге линию диаметра. Проблема в том что линия выходит за круг:

+ открыть спойлер

Приходится отдельно вырезать линии. На кнопку 1 отрезает лишнее.(можно и автоматом, просто для наглядности)

+ открыть спойлер

Эта линия рисуется от левого верхнего угла рабочей области до правого нижнего + разворот на 23 градуса
Задача: что бы линия сразу же на рисовалась нужного размера под круг, как это сделать?
