oMeta difference FW & FWH?

Marc,

You need to provide a bigger hDC. You could create a "bigger" window and get its hDC:

DEFINE WINDOW oWnd SIZE 4000, 2000

hDC = GetDC( oWnd:hWnd )
... your code
ReleaseDC( oWnd:hWnd, hDC )

oWnd:End()

Thanks,

I will try it.

Antonio,

I doesn't work.
The size of the emf-file is still the same...

Here is my testcode

Code: Select all

FUNCTION test()
   local hPEN := CreatePen( 0 , 1, 0 )
   local w := getsysmetrics(0) - 10
   local h := getsysmetrics(1) - 68
   nZFactor = 1

   DEFINE WINDOW sWnd FROM 0,0 TO 4000,4000 TITLE 'Test' VSCROLL HSCROLL
   hdc = GetDC( 0 )
   hDCOut := CreateEnhMetaFile(hdc,'tmp.emf','testje')

   MoveTo( hDCOut, 0        , 0 )
   LineTo( hDCOut, 0        ,h      , hPen)

   LineTo( hDCOut, w     ,   h    , hPen)
   LineTo( hDCOut, w     ,   0    , hPen)
   LineTo( hDCOut, 0     ,   0    , hPen)
   LineTo( hDCOut, w     ,   h    , hPen)
   LineTo( hDCOut, w     ,   0    , hPen)
   LineTo( hDCOut, 0     ,   h    , hPen)

   CloseEnhMetaFile( hDCOut )
   ReleaseDC( 0, hdc )

   oMeta := TMetaFile():New( 38, 0, w, h,'tmp.emf',sWnd,CLR_BLACK,CLR_WHITE,h,w )

   ACTIVATE WINDOW sWnd MAXIMIZED ;
   VALID ( sWndOpen := .f. , .t.)

RETURN nil

Regards,
Marc

Marc,

There are some errors in your code. Please try this:

Code: Select all

FUNCTION test() 
   local hPEN := CreatePen( 0 , 1, 0 ) 
   local w := getsysmetrics(0) - 10 
   local h := getsysmetrics(1) - 68 
   nZFactor = 1 

   DEFINE WINDOW sWnd FROM 0,0 TO 4000,4000 TITLE 'Test' VSCROLL HSCROLL 
   hdc = GetDC( sWnd:hWnd ) 
   hDCOut := CreateEnhMetaFile(hdc,'tmp.emf','testje') 

   MoveTo( hDCOut, 0        , 0 ) 
   LineTo( hDCOut, 0        ,h      , hPen) 

   LineTo( hDCOut, w     ,   h    , hPen) 
   LineTo( hDCOut, w     ,   0    , hPen) 
   LineTo( hDCOut, 0     ,   0    , hPen) 
   LineTo( hDCOut, w     ,   h    , hPen) 
   LineTo( hDCOut, w     ,   0    , hPen) 
   LineTo( hDCOut, 0     ,   h    , hPen) 

   CloseEnhMetaFile( hDCOut ) 
   ReleaseDC( sWnd:hWnd, hdc ) 

   oMeta := TMetaFile():New( 38, 0, w, h,'tmp.emf',sWnd,CLR_BLACK,CLR_WHITE,h,w ) 

   ACTIVATE WINDOW sWnd MAXIMIZED ; 
   VALID ( sWndOpen := .f. , .t.) 

RETURN nil

Antonio,

It's the same result...
The size is the same as the screen.

Marc

Antonio,

Do you have a solution for creating 'bigger' meta-files.

I allway's get the same size as the screen

Marc,

> Do you have a solution for creating 'bigger' meta-files.

We may need to create a larger hDC in memory. Several functions should be used. We are going to review it

Thanks Rossine,

I'ts working very nice.
I will try to 'translate' my program to draw directly to the window and display the drawing instead of painting first to a meta-file and than displaying it.

Regards,
Marc
