Running latest versions of OS 10.9, XCode 5.1.1 and Plugin v1.4 (Downloaded latest plugin. docs say 1.4 code comment says 1.3) Goal: Pan and zoom WebView images (similar to ability for map view) (Set up image and webview items approx 1/4 of screen pointing to a fullscreen image) Observed Using Image Item: No Pan or Zoom. (only behavior is to size/stretch image to item width and height size. Using a Web View (pointing to the same image URL), with Attempt to fit content set to No. The WebView originally would only scroll vertically, and no ability to zoom. == UPDATE ===== Editing the code "tmpWeb.scalePagesToFit = NO;" // enables horizontal scrolling. However ability to pan is inconsistent. Sometimes only able to scroll left-right or up-down. Does not pan. Note: WebView (with Attempt to fit content) does not display image, and displays text. Same as editing code to "attemptZoom = YES" ==================== Chris- How would we modify the webView code to support zoom and pan of image in: CR_ultimateScreenCreator.m ? ==================== Thanks Title Comments UPDATED...

Image is being loaded with "URL to load" similar to: http://www.mydomain.com/tests/background/Project_320x568.jpg =========== Using http://google.com same scrolling (no pan behavior) and no zoom. Maybe running into limitations of both current image and webview.... would this need a new item like an imageView?
