10 EGL Library 1) 소개 EGL(Embedded Graphic Library) 은 graphic application 개발시간을단축하고다양한 object를편리하게사용할수있도록제작되었다. EGL은다양한 object를간편하게사용할수있도록함수를제공하며, event에대한처리와 object 관리를 library내에서하도록되어있다. Event에대한추가동작은각 object별사용자 callback 함수를두어, 개발자가원하는동작의 callback 함수를작성하여사용할수있다. 2) 구성 EGL 은다음의 object 들로구성되어있다. 10
