If you want to use a … Read more
working code: public static Bitmap getWholeListViewItemsToBitmap() { ListView listview = MyActivity.mFocusedListView; ListAdapter adapter = listview.getAdapter(); int itemscount = adapter.getCount(); int allitemsheight = 0; List<Bitmap> bmps = new ArrayList<Bitmap>(); for (int i = 0; i < itemscount; i++) { View childView = adapter.getView(i, null, listview); childView.measure(MeasureSpec.makeMeasureSpec(listview.getWidth(), MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); childView.layout(0, 0, childView.getMeasuredWidth(), childView.getMeasuredHeight()); childView.setDrawingCacheEnabled(true); childView.buildDrawingCache(); bmps.add(childView.getDrawingCache()); … Read more
A quick and dirty way would be to use the WinForms WebBrowser control and draw it to a bitmap. Doing this in a standalone console app is slightly tricky because you have to be aware of the implications of hosting a STAThread control while using a fundamentally asynchronous programming pattern.

If you look at wkhtmltox, there’s native lib/app for converting a webpage to an image. <?php // file: img.php $img=render_image($_GET[‘url’]); ?> <!– Your Website –> <img alt=”ldr”/> <script type=”text/javascript”> $(document).ready(function(){ var url=”http://google.com/”; $(‘#img’).attr(‘src’,’img.php?url=”+encodeURIComponent(url)); }); </script> In case the comment wasn”t clear enough, you need PHP somewhere which could run a native program.
You are mistaken about the way array is laid out in memory, as you can find out by declaring img before the loop and adding this printf to your inner loop: printf(“%ld %ld %u %u %u\n”,x,y,pic.offset(x,y,0),pic.offset(x,y,1),pic.offset(x,y,2)); This yields (on my 1920×1200 screen): 0 0 0 2304000 4608000 0 1 1920 2305920 4609920 0 2 3840 … Read more
