It appears your function can be replaced with :-

_GDIPlus_ImageSaveToFile($Bitmap, 'E:\Media\Pictures\Raster_Proj' & '\Out_A_' & $sTrail & '.png')

Here are two methods of creating a bitmap that is saved to disk.

#include <WinAPI.au3>
#include <GDIPlus.au3>

Local $filename, $begin, $aArr, $time, $iColor
Local $hBMP, $hImage1, $hImage2, $hGraphic, $iW, $iH

$sFilename = @ScriptDir & "\TestRed.gif"
$sFilename1 = @ScriptDir & "\TestBrown.png"
$iW = 32
$iH = 32
$iColor = "0xFFFF0000"
$iColor1 = "0x654321"

$begin = TimerInit()

_FileCreateImageColor($sFilename, $iW, $iH, $iColor)

_FileCreateImageColor1($sFilename1, $iW, $iH, $iColor1)

ConsoleWrite("Time taken = " & Round(TimerDiff($begin) / 1000, 3) & " secs" & @CRLF)
ShellExecute($sFilename)
ShellExecute($sFilename1)


Func _FileCreateImageColor($filename, $iW = 32, $iH = 32, $iColor = "0xFFFFFFFF")
    $hBMP = _WinAPI_CreateBitmap($iW, $iH, 1, 32)
    _GDIPlus_Startup()
    $hImage1 = _GDIPlus_BitmapCreateFromHBITMAP($hBMP)
    $hGraphic = _GDIPlus_ImageGetGraphicsContext($hImage1)
    _GDIPlus_GraphicsClear($hGraphic, $iColor)
    _GDIPlus_GraphicsDrawImageRect($hGraphic, $hImage1, 0, 0, $iW, $iH)
    _GDIPlus_ImageSaveToFile($hImage1, $filename)
    ;__BitmapToImageFile($hImage1, $filename)
    _GDIPlus_ImageDispose($hImage1)
    _GDIPlus_GraphicsDispose($hGraphic)
    _WinAPI_DeleteObject($hBMP)
    _GDIPlus_Shutdown()
    Return
EndFunc ;==>_FileCreateImageColor

Func _FileCreateImageColor1($filename, $iW = 32, $iH = 32, $iColor = "0xFFFFFF")
    $hBMP = _WinAPI_CreateSolidBitmap(WinGetHandle(""), $iColor, $iW, $iH)
    _GDIPlus_Startup()
    $hImage1 = _GDIPlus_BitmapCreateFromHBITMAP($hBMP)
    _GDIPlus_ImageSaveToFile($hImage1, $filename)
    ;__BitmapToImageFile($hImage1, $filename)
    ;__BitmapToImageFile1($hImage1, $filename)
    _GDIPlus_ImageDispose($hImage1)
    _WinAPI_DeleteObject($hBMP)
    _GDIPlus_Shutdown()
    Return
EndFunc ;==>_FileCreateImageColor1

; ============ Testing MvGulik's function ==============
Func __BitmapToImageFile(ByRef $Bitmap, $filename)
    _GDIPlus_ImageSaveToFile($Bitmap, $filename)
    Return
EndFunc ;==>__BitmapToImageFile

Func __BitmapToImageFile1(ByRef $Bitmap, $sTrail = '')
    ;Local $sFileName = 'E:\Media\Pictures\Raster_Proj' & '\Out_A_' & $sTrail & '.png'
    Local $tmp1 = _GDIPlus_BitmapCreateHBITMAPFromBitmap($Bitmap)
    Local $tmp2 = _GDIPlus_BitmapCreateFromHBITMAP($tmp1)
    Local $sCLSID = _GDIPlus_EncodersGetCLSID('png')
    Local $res
    $res = _GDIPlus_ImageSaveToFileEx($tmp2, $sTrail, $sCLSID, 0)
    $res = _GDIPlus_ImageDispose($tmp2)
    $res = _WinAPI_DeleteObject($tmp1)
    Return
EndFunc ;==>__BitmapToImageFile1
