Примеры

В следующем примере кода показано создание ImageList, добавление изображений в Images свойство, установка ImageSize свойства и использование Draw метода. Чтобы запустить этот пример, поместите его в форму, содержащую кнопку с именем Button1. В примере предполагается наличие и Gone Fishing.bmp в FeatherTexture.bmp C:\Windows\. Измените пример соответствующим образом, если растровые изображения не существуют в системе или существуют в другом расположении.
