Example
This example shows the minimum requirements for using the L_EfxPatternFillRect function to draw and fill a rectangle with a pattern and color.
L_INT EfxPatternFillRectExample(HWND hWnd,RECT* pDest) { L_INT nRet; HDC hdc; /* Device context for the current window */ HPALETTE hSavedPalette = NULL; /* Temporary copy of the current system palette */ HPALETTE hOurPalette = NULL; /* The palette that we will use to paint */ L_INT nBitsPerPixel; /* Get the device context */ hdc = GetDC (hWnd); /* Check the device to see if we need a palette */ nBitsPerPixel = GetDeviceCaps( hdc, BITSPIXEL ) * GetDeviceCaps ( hdc, PLANES ); if ( nBitsPerPixel <=8 ) { hOurPalette = (HPALETTE)GetStockObject (DEFAULT_PALETTE); hSavedPalette = SelectPalette (hdc, hOurPalette, FALSE); /* Realize our palette */ RealizePalette (hdc); } /* Draw the pattern filled rectangle */ nRet = L_EfxPatternFillRect (hdc, /* device context */ pDest, /* destination rectangle */ EFX_PATTERN_DIAG_CROSS, /* diagonal cross pattern */ RGB ( 0,0,0 ), /* background color, black */ RGB ( 0,0,255 ) ); /* foreground color, blue */ if(nRet != SUCCESS) return nRet; /* Restore the old palette */ if ( hOurPalette ) SelectPalette (hdc, hSavedPalette, FALSE); /* Release the device context */ ReleaseDC(hWnd, hdc); return SUCCESS; }
