Returns
SUCCESS |
The function was successful. |

Example
This example starts the Magnifying Glass then calls L_SetMagGlassPaintOptions function to set the Magnifying Glass paint options.
L_INT SetMagGlassPaintOptionsExample(L_HWND hWnd, pBITMAPHANDLE pBitmap, RECT* prcView) { L_INT nRet; L_TCHAR szMsg[256]=TEXT(""); MAGGLASSPAINTOPTIONS MagGlassPntOptions; MAGGLASSOPTIONS MagGlassOpt; // Starting the Magnifying Glass memset(&MagGlassOpt, 0, sizeof(MAGGLASSOPTIONS)); MagGlassOpt.uStructSize = sizeof (MAGGLASSOPTIONS); MagGlassOpt.nWidth = 100; MagGlassOpt.nHeight = 100; MagGlassOpt.nZoom = 400; MagGlassOpt.clrPen = RGB(255,0,0); MagGlassOpt.hMagCursor = NULL; MagGlassOpt.clrBack = RGB(128,128,128); MagGlassOpt.bEllipse = FALSE; MagGlassOpt.nBorderSize = 1; MagGlassOpt.b3D = TRUE; MagGlassOpt.uPaintFlags = 0; MagGlassOpt.pMask = NULL; MagGlassOpt.uMaskCount = 0; MagGlassOpt.nCrosshair = CROSSHAIR_FINE; MagGlassOpt.bIgnoreRgn = TRUE; MagGlassOpt.bCenter = TRUE; nRet = L_StartMagGlass(hWnd, pBitmap, prcView, &MagGlassOpt, NULL, NULL); if (nRet != SUCCESS) { wsprintf(szMsg, TEXT("Error Starting the Magnifying Glass, Error: %d"), nRet); MessageBox(hWnd, szMsg, TEXT("Error"), MB_ICONEXCLAMATION | MB_OK); return nRet; } // Setting the Magnifying Glass Paint contrast, gamma and intensity MagGlassPntOptions.uStructSize = sizeof(MAGGLASSPAINTOPTIONS); MagGlassPntOptions.nContrast = 100; MagGlassPntOptions.nGamma = 100; MagGlassPntOptions.nIntensity = 100; nRet = L_SetMagGlassPaintOptions(hWnd, &MagGlassPntOptions); if (nRet != SUCCESS) { wsprintf(szMsg, TEXT("Error Setting the Magnifying Glass painting options, Error: %d"), nRet); MessageBox(hWnd, szMsg, TEXT("Error"), MB_ICONEXCLAMATION | MB_OK); return nRet; } return SUCCESS; }
