 Hi!

I need help on couple of issues .... Basically I want to capture
webpage from webview and get raster data of the bitmap.

To do so what I did is
                WebView m_browser;
 Picture picture = m_browser.capturePicture();
        Bitmap  b = Bitmap.createBitmap( picture.getWidth(),
        picture.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas c = new Canvas( b );
        picture.draw( c );

Issue 1: Out of memmory exception when web page is big for eg.  http://times.com 
What should I do to get this image? Is it possible to get image in
multiple bitmaps?

Issue 2: How can i get RGB data 24 bit data from ARGB_8888. I need to
get this 24 bit Raster data compress it with some compression and
process it...

Thanks in advance

if your image is too big create smaller one, for example two times
smaller:

  WebView browser;
  Picture p = browser.capturePicture();
  Bitmap b = Bitmap.createBitmap( p.getWidth() / 2, p.getHeight() /
2, Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);
    c.scale(0.5, 0.5);
    p.draw(c);
