Remove unwanted White Space in WebView Android

I have started developing an App using WebView. Actually I am loading an Image with Webview (I like to use the built-in zoom controls of the class). I can successfully load the Image but I can see some irritating white spaces. I can't find the way to remove it. My Images are 750 * 1000 in size. I have attached my code below.

webview.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >
    <WebView
        android:id="@+id/webView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

ImageViewer.java

package com.android.test;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class ImageViewer extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        String loadUrl = "file:///android_res/drawable/splash_001.jpg";

        WebView image = (WebView) findViewById(R.id.webView);
        image.clearView();
        image.clearCache(true);
        image.getSettings().setBuiltInZoomControls(true);
        image.getSettings().setSupportZoom(true);
        image.getSettings().setLoadWithOverviewMode(true);
        image.getSettings().setUseWideViewPort(true);
        image.loadUrl(loadUrl);
    }

}
