Hi, Sorry for the delayed response. I have attached an modified version of our core.touch.events.js file which should allow you to use pinch zoom on your iOS device. Please be aware that due to the complexity of our UI dealing with user selection, multiple scrolling panels and context menus, enabling this feature provides a somewhat different user experience, which some may consider worse. To use: Go to the scripts directory located in your jasperserver installation folder. Rename the current core.touch.events.js file to core.touch.events.old.js. Copy the attached file to scripts folder. You don't have to restart jasperserver. Just reload the page.We hope this helps you achieve your goals with Jasperserver. Gerald Truong. Client-side Team.
