Merhaba,<\/p>\n
Bu makalemizde C# Windows Form uygulamas\u0131nda \u00e7izgi \u00e7izmeyi irdeleyecek ve \u00f6rnek bir Paint uygulamas\u0131 \u00fczerinde i\u00e7eri\u011fimizi kuvvetlendirece\u011fiz. Windows Form uygulamalar\u0131nda forma \u00e7izgi \u00e7izebilmek i\u00e7in k\u00e2h Graphics s\u0131n\u0131f\u0131 \u00fczerinden Draw ile ba\u015fayan metodlar\u0131 kullanabilir k\u00e2h tek tek pixeller \u00fczerinde i\u015flemler yapabiliriz. Tabi burada ilk verdi\u011fim Graphics s\u0131n\u0131f\u0131 kullan\u0131larak \u00e7izilen \u00e7izgiler genellikle \u015fekillerden olu\u015fan yap\u0131lar\u0131 bar\u0131nd\u0131rmaktayken, tek tek pixellere m\u00fcdahale ederek \u00e7izdirdiklerimiz kullan\u0131c\u0131n\u0131n mouse ile olan insiyatifine ba\u011fl\u0131 tarifsiz \u00e7izgileri ifade etmektedir.<\/p>\n
Biz bu i\u00e7eri\u011fimizde ikinci \u00f6neri olan pixellere m\u00fcdahale y\u00f6ntemiyle \u00e7izim yapmay\u0131 inceleyece\u011fiz.<\/p>\n
Hemen konuya giri\u015f yapabilmek maksad\u0131yla a\u015fa\u011f\u0131daki gibi bir form tasarlayal\u0131m.<\/p>\n

Evet \u015fimdi \u00e7izim i\u015flemimize ge\u00e7ebiliriz.
