Keywords: Cc:

Description

to fix:
in GDIPlus.au3,
in function _GDIPlus_BitmapCreateFromMemory,
replace this:

        Local Const $hBitmap = _GDIPlus_BitmapCreateFromStream($hStream) ;creates a Bitmap object based on an IStream COM interface
        If @error Then Return SetError(3, 0, 0)
        DllCall("oleaut32.dll", "long", "DispCallFunc", "ptr", $hStream, "ulong_ptr", 8 * (1 + @AutoItX64), "uint", 4, "ushort", 23, "uint", 0, "ptr", 0, "ptr", 0, "str", "") ;release memory from $hStream to avoid memory leak

with this:

        Local Const $hBitmap = _GDIPlus_BitmapCreateFromStream($hStream) ;creates a Bitmap object based on an IStream COM interface
        Local $error = @error
        DllCall("oleaut32.dll", "long", "DispCallFunc", "ptr", $hStream, "ulong_ptr", 2 * (@AutoItX64 ? 8 : 4), "uint", 4, "ushort", 23, "uint", 0, "ptr", 0, "ptr", 0, "str", "") ;release memory from $hStream to avoid memory leak (2 is the offset of the Release method of IUnknown in its vtable)
        If $error Then Return SetError(3, 0, 0)
