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。
