nFlags
Number: Draw flags

Example
In this example an image is drawn centered into a window:
! Get the DC
Set hDC = GetDC( hWnd )
If hDC
! Get the image size
Call MImgGetSize( hImage, nWidth, nHeight )
! Get the client rectangle of the window
Call GetClientRect( hWnd, nLeft, nTop, nRight, nBottom )
! Calculate the draw rectangle
Set nLeft = SalNumberTruncate( SalNumberMax( 0, ( ( nRight - nLeft ) - nWidth ) / 2 ), 10, 0 )
Set nTop = SalNumberTruncate( SalNumberMax( 0, ( ( nBottom - nTop ) - nHeight ) / 2 ), 10, 0 )
Set nRight = nLeft + nWidth
Set nBottom = nTop + nHeight
! Draw it
Call MImgDraw( hImage, hDC, nLeft, nTop, nRight, nBottom, 0 )
! Release the DC
ReleaseDC( hWnd, hDC )
