Developer's Image Library (DevIL) is a programmer's library to develop applications with very powerful image loading capabilities, yet is easy for a developer to learn and use

Ultimate control of images is left to the developer, so unnecessary conversions, etc. are not performed. DevIL utilizes a simple, yet powerful, syntax. DevIL can load, save, convert, manipulate, filter and display a wide variety of image formats.

Just reading the DevIL manual here. Also reminded me of glGenBuffers. Why did they choose to have the user of each library generate names (pg. 6 in the DevIL manual), rather than specifying names for your own images/buffers and so on? I thought…
