// stb_rect_pack.h - v0.10 - public domain - rectangle packing
|

|
// Sean Barrett 2014
|
||||||
|
//
|
||||||
|
// Useful for e.g. packing rectangular textures into an atlas.
|
||||||
|
// Does not do rotation.
|
||||||
|
//
|
||||||
|
// Not necessarily the awesomest packing method, but better than
|
||||||
|
// the totally naive one in stb_truetype (which is primarily what
|
||||||
|
// this is meant to replace).
|
||||||
|
//
|
||||||
|
// Has only had a few tests run, may have issues.
|
||||||
|
//
|
||||||
|
// More docs to come.
|
||||||
|
//
|
||||||
|
// No memory allocations; uses qsort() and assert() from stdlib.
|
||||||
|
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
||||||
|
//
|
||||||
|
// This library currently uses the Skyline Bottom-Left algorithm.
|
||||||
|
//
|
||||||
|
// Please note: better rectangle packers are welcome! Please
|
||||||
|
// implement them to the same API, but with a different init
|
||||||
|
// function.
