You think that fivewin can have comand native to use PNG ? because it use DLL freeimage, i think that it´s time of
fivewin have it native.

thanks so much for your help.

Note: ( Itryed too ON PAINT PalBmpDraw( hDC, 0, 0, oBmp1:hBitmap ) more too no work fine.. )

Hello Lailton

Yes, i saw you problem, but is freeimagen fault.
is possible have PNG native, but no for now
you should convert png to alphabitmap

sample:

Code: Select all | Expand

#include "FiveWin.ch"
function Main()

   local oWnd, oBmp1
   DEFINE WINDOW oWnd STYLE WS_POPUP COLOR CLR_WHITE,CLR_WHITE

          oBmp1:=TImage():new(0,0,120,125,,"test.bmp",.t.,ownd)
          oBmp1:lTransparent:=.t.
          oWnd:Center()
          SetTransparent( oWnd )

   ACTIVATE WINDOW oWnd ON PAINT PaintTransparent( hDC, oBmp1:hBitmap, 0, 0 ) 
   oBmp1:End()

return nil
//---------------------------------------------------------------------------------------------------//
#define LWA_COLORKEY  1 
#define GWL_EXSTYLE   -20 
#define WS_EX_LAYERED 524288 
//---------------------------------------------------------------------------------------------------//
STATIC FUNCTION SETTRANSPARENT( oDlg ) 
   SETWINDOWLONG( oDlg:hWnd, GWL_EXSTYLE, NOR( GETWINDOWLONG( oDlg:hWnd, GWL_EXSTYLE ), WS_EX_LAYERED ) ) 
   SETLAYEREDWINDOWATTRIBUTES( oDlg:hWnd, CLR_WHITE,, LWA_COLORKEY ) 
RETURN NIL
//---------------------------------------------------------------------------------------------------//
function PaintTransparent( hDC, hBitmap, nRow, nCol )
   local hBmpOld := SelectObject( hDC, hBitmap )
   local nZeroZeroClr := GetPixel( hDC, 0, 0 )
   local nOldClr 
   SelectObject( hDC, hBmpOld )
   nOldClr = SetBkColor( hDC, CLR_WHITE )
   TransBmp( hBitmap, nBmpWidth( hBitmap ), nBmpHeight( hBitmap ), nZeroZeroClr, hDC, nRow, nCol, nBmpWidth( hBitmap ), nBmpHeight( hBitmap ) )
   SetBkColor( hDC, nOldClr )          
return nil
//---------------------------------------------------------------------------------------------------//

Daniel,

The problem using as bmp is:

Size of file is but..

png file have 8,106 Bytes
bmp file have 60,056 Bytes

Quality

It´s very good !


It´s +/- ( but to bad ... )



How i say before, png is execellent, all language have suport this, think that it´s time
of fivewin too have native suport and remove freeimage.dll ( or use only to bmp file.. )

other ASK

that program you use to convert png to bmp ?

thanks.
