Developer's Image LibraryorDevIL,started by Denton Woods, is across-platformimage library which aims to provide a commonAPIfor different imagefile formats.It consists of three parts: the main library (IL), the utility library (ILU) and the utility toolkit (ILUT), mirroring the corresponding parts ofOpenGL(although theOpenGL Utility Toolkitis not part of the OpenGL specification).[1]
It was originally calledOpenIL;the name was changed at a request fromSilicon Graphics, Inc.[2]
DevIL currently[when?]supports 43 file formats for reading and 17 for writing; among those with read-write support areBMP,DDS,JPEG,PCX,PNG,raw,TGA,andTIFF.The actual supported formats depend on compilation settings, in particular, external libraries likelibjpegandlibpng.[3]
On June 9, 2010, Woods announced that he had submitted a request to change the licensing terms from theGNU LGPLto aBSD license.[citation needed]According to the website (as well as the source repository), DevIL is still licensed under the terms of the LGPL.[4]DevIl is listed in the directory of theFree Software FoundationasFree Software.[5]
