I tried to use imwrite
to successfully to display an image on a Windows Form, but it damages the disk, so I need a better way to do this.
Below, is my c
It is definitely a good idea to get away from writing the image to a file and then immediately reading back onto a control. It is quite inefficient as the hard drive is the slowest memory device in the system usually.
I do not believe you are using the correct Bitmap
constructor in your example above. You should probably be using this constructor definition. Also, telling the Bitmap
object that the PixelFormat
is undefined is probably not helping things either. I'm assuming you have a color camera that is returning a CV_8UC3
matrix (i.e., your PixelFormat == Format24bppRgb
).
How about try a call like this:
this->panel1->BackgroundImage = gcnew System::Drawing::Bitmap(frame.size().width,
frame.size().height,
frame.step,
PixelFormat::Format24bppRgb,
(IntPtr)frame.data);
Also, remember that OpenCV natively stores color in BGR format. So, you may need to swap the red and blue channels to get the data to look right.
Hopefully, that will get you started!
