1*
2* rl_gputex v1.1 - GPU compressed textures loading and saving
3*
4* DESCRIPTION:
5*
6* Load GPU compressed image data from image files provided as memory data arrays,
7* data is loaded compressed, ready to be loaded into GPU
8*
9* Note that some file formats (DDS, PVR, KTX) also support uncompressed data storage.
10* In those cases data is loaded uncompressed and format is returned
11*
12* FIXME: This library still depends on Raylib due to the following reasons:
13* - rl_save_ktx_to_memory() requires rlGetGlTextureFormats() from rlgl.h
14* though this is not a problem, if you don't need KTX support
15*
16* TODO:
17* - Review rl_load_ktx_from_memory() to support KTX v2.2 specs
18*
19* CONFIGURATION:
20*
21* #define RL_GPUTEX_SUPPORT_DDS
22* #define RL_GPUTEX_SUPPORT_PKM
23* #define RL_GPUTEX_SUPPORT_KTX
24* #define RL_GPUTEX_SUPPORT_PVR
25* #define RL_GPUTEX_SUPPORT_ASTC
26* Define desired file formats to be supported
27*
28* #define RL_GPUTEX_SHOW_LOG_INFO
29* Define, if you wish to see warnings generated by the library
30* This will include <stdio.h> unless you provide your own RL_GPUTEX_LOG
31* #define RL_GPUTEX_LOG
32* Define, if you wish to provide your own warning function
33* Make sure that this macro puts newline character '\n' at the end
34*
35* #define RL_GPUTEX_MALLOC
36* #define RL_GPUTEX_FREE
37* Define those macros in order to provide your own libc-compliant allocator;
38* not doing so will include <stdlib.h>
39* If you're providing any of those, you must provide ALL of them,
40* otherwise the code will (most likely) crash...
41*
42* #define RL_GPUTEX_NULL
43* Define in order to provide your own libc-compliant NULL pointer;
44* not doing so will include <stdlib.h>
45*
46* #define RL_GPUTEX_MEMCPY
47* Define in order to provide your own libc-compliant 'memcpy' function;
48* not doing so will include <string.h>
49*
50* #define RLGPUTEXAPI
51* Define to compiler-specific intrinsic, if you wish to export public functions
52* There is no need to do so when statically linking
53*
54* VERSIONS HISTORY:
55* 1.1 (15-Jul-2025) Several minor fixes related to specific image formats; some work has been done
56* in order to decouple the library from Raylib by introducing few new macros; library still
57* requires Raylib in order to function properly
58*
59* 1.0 (17-Sep-2022) First version has been created by migrating part of compressed-texture-loading
60* functionality from Raylib src/rtextures.c into self-contained library
