// stb_rect_pack.h - v1.01 - public domain - rectangle packing
|
||||
// Sean Barrett 2014
|
||||
//
|
||||
// Useful for e.g. packing rectangular textures into an atlas.
|
||||
// Does not do rotation.
|
||||
//
|
||||
// Before #including,
|
||||
//
|
||||
// #define STB_RECT_PACK_IMPLEMENTATION
|
||||
//
|
||||
// in the file that you want to have the implementation.
|
||||
//
|
||||
// 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.

// 1.00 (2019-02-25) avoid small space waste; gracefully fail too-wide rectangles
|
||||
// 0.99 (2019-02-07) warning fixes
|

||||
// 0.07 (2015-09-13) fix bug with empty rects (w=0 or h=0)
|
||||
// 0.06 (2015-04-15) added STBRP_SORT to allow replacing qsort
|
||||
// 0.05: added STBRP_ASSERT to allow replacing assert
