How to create a pbitmap from graphics?

[memerim]

If i get a graphics from a call _GDIPlus_GraphicsCreateFromHDC

How do i convert this graphics to a bitmap?

What the function below return, isn't a bitmap?

Func _GDIPlus_BitmapCreateFromGraphics($iWidth, $iHeight, $hGraphics)
   Local $aResult = DllCall($__g_hGDIPDll, "int", "GdipCreateBitmapFromGraphics", "int", $iWidth, "int", $iHeight, "handle", $hGraphics, _
         "handle*", 0)
   If @error Then Return SetError(@error, @extended, 0)
   If $aResult[0] Then Return SetError(10, $aResult[0], 0)

   Return $aResult[4]
EndFunc   ;==>_GDIPlus_BitmapCreateFromGraphics

 

Theres an example in the docs:

But the variable name is $g_hBitmap? hBitmap?

Trying to understand how to use the function to get a bitmap from a graphics and save it to disk.

If you want to know how to save the contents of a Graphics object to a bitmap, then the answer is that there's no direct approach for doing so.this how you save Bitmap from Graphics and save it to Disk.

$g_hGfx = _GDIPlus_GraphicsCreateFromHWND($g_hGUI) ;create a graphics object from a window handle
 $g_hBitmap = _GDIPlus_BitmapCreateFromGraphics($iWidth, $iHeight, $g_hGfx) ;create a Bitmap object based on a graphics object
 _GDIPlus_ImageSaveToFile($g_hBitmap,"D:\image.bmp");Save the bitmap to a file on disk, or do whatever else with it

_GDIPlus_BitmapCreateFromGraphics2

Its a different function? or did you mean FromGraphics?

I mean from a hdc not a window.

@memerim

i mean't from Graphics.

From HDC:

$g_hGfx =  _GDIPlus_GraphicsCreateFromHDC($hdc) ;create a graphics object from a hdc
 $g_hBitmap = _GDIPlus_BitmapCreateFromGraphics($iWidth, $iHeight, $g_hGfx) ;create a Bitmap object based on a graphics object
