Bitmap2

I´m trying to use bitmap2 but it does not work and no errors are shown in console this is the code

    private function drawBackground(dc as Dc) as Void {
        if (null != _offscreenBuffer) {
            if ( Graphics.Dc has :drawBitmap2 ){
            dc.drawBitmap2(0, 0, _offscreenBuffer, {:tintColor => mFgColor});
            }else{
            dc.drawBitmap(0, 0, _offscreenBuffer);
            }
        }
    }

and this is the bitmap.xml file I have also try automatic palette false and true

<resources>
    <bitmap id="Evertop" filename="drawables/Evertop.png">
        <palette disableTransparency="true">
			<color>000000</color>
            <color>AAAAAA</color>
            <color>555555</color>
        </palette>
    </bitmap>
    
    <bitmap id="Evertopd" filename="drawables/Evertopd.png">
        <palette disableTransparency="true">
			<color>000000</color>
            <color>AAAAAA</color>
            <color>555555</color>
            <color>AA0000</color>
        </palette>
    </bitmap>
</resources>

I don´t know if it works
