I load a local HTML template into a WebView. My webview's frame size is very small (250X300). I use this to show only a preview. The problem is, I can't see the entire html content in the webview. I can see only the top left. I have to scroll to see the entire content. So is there any possiblity to set the scale or zoom factor for the webview?
