我剛剛看到以前的文章~是在做ccd擷取到的兩張圖做相減~但是這個元件BN_subtractClick我不知從哪叫出來~~拜託各位大大指點一下路徑~謝謝 //---------------------------------------------------------------------------        void __fastcall TForm1::BN_subtractClick(TObject *Sender)     {        for (int i=0;ibuffer2[i]) buffer3[i]=buffer1[i]-buffer2[i]; else buffer3[i]=buffer2[i]-buffer1[i]; } capGrabFrameNoStop(hCapWnd); //從CCD中抓取單格影像，但不會停止其他動作 capEditCopy(hCapWnd); TMemoryStream *stream=new TMemoryStream; HDC ScreenDC=GetDC(hCapWnd); Graphics::TBitmap *bmp1=new Graphics::TBitmap(); bmp1->Width = CapWidth; bmp1->Height = CapHeight; bmp1->PixelFormat=pf24bit; StretchBlt(bmp1->Canvas->Handle,0,0,CapWidth,CapHeight, ScreenDC,0,0,CapWidth,CapHeight,SRCCOPY); stream->Position=0; stream->Clear(); stream->SetSize(bmpFileSize); bmp1->SaveToFile("image3.bmp"); stream->Position = 0; stream->Write(buffer3,bmpFileSize); stream->Position = 0; Image3->Picture->Bitmap->LoadFromStream(stream); delete stream; delete bmp1; } 發表人 - 639673 於 2005/07/26 13:21:52
