Hello I am working on a Pylon Application, and I want to know how to draw image which is in array.
Basler's Pylon SDK, on memory Image saving
In this link, it shows I can save image data in array(I guess) Pylon::CImageFormatConverter::Convert(Pylon::CPylonImage[i],Pylon::CGrabResultPtr)
But the thing is I can not figure out how to draw that images which is in array.
I Think it would be easy problem, but I'd appreciate it if you understand because it's my first time doing this.

For quick'n dirty displaying of Pylon buffers, you have a helper class available in Pylon SDK to put somewhere in buffer grabbing loop:
//initialization
CPylonImage img;
CPylonImageWindow wnd;
//somewhere in grabbing loop
wnd.SetImage(img);
wnd.Show();
If you want to utilize in your own display procedures (via either GDI or 3rd party libraries like OpenCV etc.), you can get image buffer with GetBuffer() method:
CGrabResultPtr ptrGrabResult;
camera.RetrieveResult( 5000, ptrGrabResult, TimeoutHandling_ThrowException);
const uint8_t *pImageBuffer = (uint8_t *) ptrGrabResult->GetBuffer();
Of course, you have to be aware of your target pixel alignment and optionally use CImageFormatConverter for proper output pixel format of your choice.
