对于这种情况，你可以像这样在Winform控件中绘制你的cv图像。

< pre class ="prettyprint"> void DrawCVImage（System :: Windows :: Forms :: Control ^ control，cv :: Mat& colorImage）
{
System :: Drawing :: Graphics ^ graphics = control - >的createGraphics（）;
System :: IntPtr ptr（colorImage.ptr（））;
。系统::绘图::位图^ B = gcnew系统::绘图::位图（colorImage.cols，colorImage.rows，colorImage.step，系统::绘图::成像::的PixelFormat :: Format24bppRgb，PTR ）;
System :: Drawing :: RectangleF rect（0,0，control-> Width，control-> Height）;
graphics-> DrawImage（b，rect）;
删除图形;
}

或者将你的cv图像转换为位图对象，然后在你的图片框中绘图。

 Mat matImage = imread（" image.bmp"，CV_LOAD_IMAGE_COLOR）; 
 cvtColor（matImage，matImage，CV_BGRA2RGBA）; 
 
 HBITMAP = CreateBitmap（matImage.cols，matImage.rows，1，32，matImage.data）; 

希望这你可以帮助。

I want to get my camera feed displayed in the PictureBox in Visual c++ CLR application. What should I include in the pictureBox callback in myform.h? What should I include in the .cpp file?

Thank you for your help.

Hi fMax6,

thanks for posting here.

For this case, you could draw your cv image in Winform control like this.

void DrawCVImage(System::Windows::Forms::Control^ control, cv::Mat& colorImage)
{
    System::Drawing::Graphics^ graphics = control->CreateGraphics();
    System::IntPtr ptr(colorImage.ptr());
    System::Drawing::Bitmap^ b  = gcnew System::Drawing::Bitmap(colorImage.cols,colorImage.rows,colorImage.step,System::Drawing::Imaging::PixelFormat::Format24bppRgb,ptr);
    System::Drawing::RectangleF rect(0,0,control->Width,control->Height);
    graphics->DrawImage(b,rect);
    delete graphics;
}

Or convert your cv image to bitmap object, then draw in your picturebox.

Mat matImage = imread("image.bmp", CV_LOAD_IMAGE_COLOR);
cvtColor(matImage, matImage, CV_BGRA2RGBA);

hBitmap = CreateBitmap(matImage.cols, matImage.rows, 1, 32, matImage.data);

Hope this could be help of you.
