MFC窗口怎么显示halcon采集到的图片

Question

在halcon上连接相机采集了图像，之后把这个部分的cpp代码导出了，如下：
void action()
{

// Local iconic variables
HObject ho_Image;

// Local control variables
HTuple hv_AcqHandle;

//Image Acquisition 01: Code generated by Image Acquisition 01
OpenFramegrabber("USB3Vision", 0, 0, 0, 0, 0, 0, "progressive", -1, "default", -1, "false", "default", "2BA200001454_DahengImaging_MER050560U3C", 0, -1, &hv_AcqHandle);
GrabImageStart(hv_AcqHandle, -1);
while (0 != 1)
{
GrabImageAsync(&ho_Image, hv_AcqHandle, -1);
}
CloseFramegrabber(hv_AcqHandle);
}

想新建一个MFC文件，之后在串口设一个按钮，把上述代码放到按钮代码里，但是问题是怎么才能让采集到的图像显示在窗口的PictureControl控件上呢？
查阅了一些资料有的说用OpenWindow和dispobj，但是好像需要涉及到图片数据类型的转换？求大神解答

Answer 1

是涉及转换问题，主要是把halcon类型转换为数组，然后根据宽高设置到控件，8位图用get_image_pointer1，24位图用get_image_pointer3，以下是我写的转换函数，你可以参考一下：

#ifdef HALCON11
int ConvertHalcon11ToKSJ(HObject Image, unsigned char ** ppImageData)//ppImageData在接口调用后需要释放
{
#else
int ConvertHalcon10ToKSJ(Hobject Image, unsigned char ** ppImageData)
{
#endif

    mirror_image(Image, &Image, "row");//上下反转图片
    HTuple     Hchannels;
    count_channels(Image, &Hchannels);
    int nChannels = Hchannels[0].I();
    HTuple     Htype;
    HTuple     Hwidth, Hheight;
    unsigned char * pTempData = NULL;
    if (nChannels == 1)//根据位图深度调用相应接口
    {
        HTuple hpoint;
        get_image_pointer1(Image, &hpoint, &Htype, &Hwidth, &Hheight);
        int nLineByte = MAKEWIDTHBYTES(Hwidth[0].I(), 8);
        pTempData = new unsigned char[nLineByte * Hheight[0].I()];
        unsigned char *  ptr = (unsigned char *)hpoint[0].L();
        for (int i = 0; i < Hheight[0].I(); i++)//深拷贝
        {
            memcpy(pTempData + i * nLineByte, ptr + i * Hwidth[0].I(), Hwidth[0].I());
        }
    }
    else if (nChannels == 3 || nChannels == 4)
    {
        HTuple Hred;
        HTuple Hgreen;
        HTuple Hblue;
        get_image_pointer3(Image, &Hred, &Hgreen, &Hblue, &Htype, &Hwidth, &Hheight);
        int nLineByte = MAKEWIDTHBYTES(Hwidth[0].I(), nChannels * 8);
        pTempData = new unsigned char[nLineByte * Hheight[0].I()];
        unsigned char *  ptr_red   = (unsigned char *)Hred[0].L();
        unsigned char *  ptr_green = (unsigned char *)Hgreen[0].L();
        unsigned char *  ptr_blue  = (unsigned char *)Hblue[0].L();
        for (int i = 0; i < Hheight[0].I(); i++)//将红、绿、蓝保存到像素中
        {
            int nOffset     = i * Hwidth[0].I();
            int nRealOffset = i * nLineByte;
            for (int j = 0; j < Hwidth[0].I(); j++)//深拷贝
            {
                int nPixelOffset = j * nChannels;
                pTempData[nRealOffset + nPixelOffset + 2] = ptr_red[nOffset + j];
                pTempData[nRealOffset + nPixelOffset + 1] = ptr_green[nOffset + j];
                pTempData[nRealOffset + nPixelOffset]     = ptr_blue[nOffset + j];
            }
        }
    }
    else
    {
        return -1;
    }

    *ppImageData = pTempData;
    return 0;
}
