FillMemory

[mestnyi]

in macos fillmemory clears the canvas and sets the transparency and it works very well, is it possible to make it so that both Windows and Linux have the same behavior.

Code: Select all

Global BackgroundColor, img = LoadImage( #PB_Any, #PB_Compiler_Home + "examples/sources/Data/Geebee2.bmp" ) 
Global hole = CreateImage( #PB_Any,100,100,32 )

If StartDrawing( ImageOutput( hole ) )
  DrawingMode( #PB_2DDrawing_AllChannels )
  Box( 0,0,OutputWidth(),OutputHeight(),RGBA( $00,$00,$00,$00 ) )
  Circle( 50,50,48,RGBA( $00,$FF,$FF,$FF ) )
  Circle( 50,50,30,RGBA( $00,$00,$00,$00 ) )
  StopDrawing( )
EndIf

Global alpha = 45
OpenWindow(0, 0, 0, 300, 300, "Test", #PB_Window_SystemMenu|#PB_Window_ScreenCentered)
SetWindowColor(0, $C0AED7F2)

StartDrawing(WindowOutput(0))
BackgroundColor = Point(0, 0)
StopDrawing()

ButtonGadget(10, 10, 10, 280, 80, "button")
CanvasGadget(0, 10, 10, 280, 280)

If StartDrawing( CanvasOutput( 0 ) )
  FillMemory( DrawingBuffer( ), DrawingBufferPitch( ) * OutputHeight( ), alpha )
  
  DrawingMode( #PB_2DDrawing_Default )
  ;DrawingMode( #PB_2DDrawing_AlphaBlend )
   
  DrawImage( ImageID( Img ),50,50 )
  DrawImage( ImageID( hole ),130,130 )
  StopDrawing( )
EndIf

Repeat
  Event = WaitWindowEvent()
  
  Select Event
    Case #PB_Event_CloseWindow
      Exit = #True
  EndSelect
  
Until Exit
