以下是openCV開啟Camera的片段code
=========================================================
CvCapture* capture = 0;
capture = cvCaptureFromCAM(0);
IplImage *frame; ------------------------------>opencv定義存放frame的地方

cvNamedWindow( "result", 0 ); ---------------->new一個windoe

if( capture )
{
for(;;)
{ //Edit1->Text=IntToStr(frame->nSize);
if( !cvGrabFrame( capture ))
break;
frame = cvRetrieveFrame( capture );
if( !frame )
break;

cvShowImage( "result", frame );----------->將frame丟到window並利用無限迴圈持續show

if( cvWaitKey( 10 ) >= 0 )
break;
}
cvReleaseCapture( &capture );
}
==========================================

Camera確實可以Show也可以控制PTZ
但是我希望將某一個frame，在Image元件上畫出來，也就是要取像
畫的方法例如: Image->Canvas->Pixels[x][y]=??????????????
但是???????的地方卻不知道該如何取得IplImage *frame的RGB值
不知道有沒有高手會呢???為小弟解惑!!謝謝!!

    }
    IplImage;
是這個嗎?
frame->imageData[?]
用整個imageData copy 進到 Bitmap->ScanLine[] 會不會比較好
