Привет!
Я почти разобрался с тем, как мне работать с картой в компоненте TImage, осталось одно (и еще кое-что). Сейчас задача такая: мне нужно при клике мышки на компоненте TImage распознавать цвет пикселя, над которым в момент клика находился курсор мышки. Видимо это нужно сделать при помощи передачи координат, но куда?? кому?? какие свойства нужно использовать.
Подскажите пожалуйста, кто знает или кто пробовал..
Пишу на BDS 2006.
Заранее, большущее спасибо!!

есть вот такие методы а Канваса.. но среди них того, что мне нужно.. GetPixel и SetPixel .. Как быть?? хочу узнать цвет пикселя.. ((((((( очень нужно..

Еще пишут, что для того чтобы узнать цвет пикселя jpg-файла его неодходимо в bitmap перевести... но как? Как все это сделать на BDS?? КОШМАР...

Нашел вот что:
с формой работает.

Но если пишу вот так, то ругается на то, что картинка эта нея вляется bitmap'ом . Что делать?
и на правильном ли я пути? ..
