新版的图像用sdk，虽然有点难用，不过对没时间的人很有帮助。-Developer’s Image Library was previously called OpenIL, but due to trademark issues,

OpenIL is now known as DevIL.

DevIL is an Open Source programming library for programmers to incorporate into

their own programs. DevIL loads and saves a large variety of images for use in a software

developer’s program. This library is capable of manipulating images in various ways and

passing image information to display APIs, such as OpenGL and Direct3D.

The purpose of this manual is to guide users in coding with the Developer’s Image

Library. This manual is for users proficient in C and with competent knowledge of the

integrated development environment (IDE) or compiler they are using.
