推荐一个c++小巧开源且跨平台的图像解码库

该图像解码库仅仅三个文件。

图像处理封装:

spot.cpp

spot.h

解码库实现:

spot.c

支持图片文件格式如下:

File format	Read	Write
BMP files	yes	yes
CRN files	yes	no
DDS DXT1/2/3/4/5 files	yes	yes
GIF files	yes	no
HDR files	yes	no
JPG files (progressive)	yes	no
JPG files	yes	yes
KTX (ETC1) files	yes*	yes*
KTX (PVRTC) files	yes*	no
PIC files	yes	no
PKM (ETC1) files	yes	yes
PNG files	yes	yes
PNM (PPM/PGM) files	yes	no
PSD files	yes	no
PUG files	yes	yes
PVR2 (PVRTC) files	yes*	no
PVR3 (ETC1) files	yes*	no
PVR3 (PVRTC) files	yes*	yes*
SVG files (rasterized)	yes	no
TGA files	yes	yes
WEBP files	yes	yes

由于该解码库加载图像默认会转换hsla色域，故本人对其进行了优化，并且修正了一部分解码库的bug。
