stb-imageC 开发的图像读取解析库
C 语言开发的一个简单易用的图像读取解析库,也是 Duilib 上用到的图像解析库。
使用示例代码如下:
#include <stdio.h> #define STB_IMAGE_WRITE_IMPLEMENTATION #include "stb_image_write.h" #define STB_IMAGE_IMPLEMENTATION #include "stb_image.h" int main(int argc, char** argv) { int w, h, n; //rgba //load image unsigned char *data = stbi_load("rgba.png", &w, &h, &n, 0); printf("%d, %d, %d\n", w, h, n); //change pixel //rgba,write 10 red pixel at line 11 for (int dx = 0; dx < 10; ++dx) { data[n * w * 10 + dx * n + 0] = 255; data[n * w * 10 + dx * n + 1] = 0; data[n * w * 10 + dx * n + 2] = 0; data[n * w * 10 + dx * n + 3] = 255; } //write image stbi_write_png("write.png", w, h, n, data, w * 4); stbi_image_free(data); return 0; }
开源协议是 public domain 和 MIT。
