怎么将go struct 转为 C struct? 提取人脸特征的时候，咋感觉arr没有赋值呢？

i use go mod. this is some wrong below when i go get github.com/windosx/face-engine/v2:

go: downloading github.com/windosx/face-engine/v2 v2.2.0

官网sdk最高是3.0；用你的v4版本搭配3.0的sdk会报错：CGO找不到ASFGetActiveDeviceInfo函数。。。

还有，用你的v3版本搭配sdk3.0可以编译通过，但是提示appkey错误，错误码28674

在 Mac 上按 Linux 将 libarcsoft_face.so、libarcsoft_face_engine.so 放入 /usr/lib 目录后运行报错。

github.com/windosx/face-engine/v4
ld: library not found for -larcsoft_face_engine
clang: error: linker command failed with exit code 1 (use -v to see invocation)

请问此库支持 Mac 平台吗？

需要你帮助，怎么样可以联系到你

如题

求问

1、linux centos7.6
2、sdk包，Linux_x64_V3.0 (https://arcfacepackages.blob.core.chinacloudapi.cn/arcface-packages/sdk/arcface/linux/ArcSoft_ArcFace_Linux_x64_V3.0.zip)
3、代码，如readme

错误信息

首先感谢作者将虹软的sdk绑定到go，在今天偶发的一个bug，在engine.go的第296行
byteArr := (*[1 << 28]byte)(unsafe.Pointer(asfFaceFeature.feature))[:height:height] //如果图片中的人脸特征提取失败会导致asfFaceFeature.feature为nil，从而导致这里抛出panic，对应虹软sdk的错误代码为：81925

可通过修改为以下代码，或在提取特征逻辑中加入判断是否为nil的逻辑来解决
byteArr := (*[1 << 28]byte)(unsafe.Pointer(asfFaceFeature.feature)) //删除[:height:height]

如题，windows或linux都行

//#cgo LDFLAGS : -L${SRCDIR} -larcsoft_face_engine

你好，我在linux下使用，这个库文件必须放/usr/lib下，怎么进行调整到项目目录下。

找了很多的，没有找到相关的内容，特来请教下

拜读了你的代码，非常不错的工作，看到你的Util，有几个小建议

1. 没有必要进行resize，因为虹软的要求是 4 的倍数的宽度，读取 rgba 数组的时候，可以直接取整

for starty := 0; starty < height; starty++ {
for startx := 0; startx < newWidth; startx++ { <---- 这里直接读到4 的倍数即可
R := imgMatrix[starty][startx][0]
G := imgMatrix[starty][startx][1]
B := imgMatrix[starty][startx][2]
bgrData = append(bgrData, B, G, R)
}
}

2. util 的接口都是 文件 filename ，可以改一下，有时候是从网络上读取的字节流

3. image 转换 nrgba 可以直接 用
   "golang.org/x/image/draw"

b := src.Bounds()
m := image.NewNRGBA(image.Rect(0, 0, b.Dx(), b.Dy()))
draw.Draw(m, m.Bounds(), src, b.Min, draw.Src)

最近按照您的方法去做3.0版的SDK，问题太多了，做不下去

Linux，go1.17.6，gcc9.3.0.

在多协程抽取图片特征的时候，会间歇性的报错，导致项目退出，但是使用虹软其他功能就从来没出现过问题
