+ | PMA.UI's viewport offers different ways to zoom in on a slide. | ||
+ | |||
+ | The simplest way is to use the scrollwheel on your mouse: pushing the scrollwheel forward (away from you) lets your zoom in; bringing it toward you (or scrolling //backwards//) zoom out again. Furthermore, we've optimized the speed of interaction so that you can go from the highest level of viewing to the deepest level in one smooth sweeping motion. | ||
+ | |||
+ | If you don't have a mouse, or want precision control, you can use the zoom controls in the top-left corner of the screen, too. There are plus and minus button to zoom in (increase magnification) or zoom out (reduce magnification). | ||
+ | |||
+ | {{ ::viewport_zooming1.png?direct&200 |}} | ||
+ | |||
+ | There is also the zoombar. You interact with that one by moving the slider up and down to control your magnification. | ||
+ | |||

+ | |||
+ | The zoombar is useful even if you don't use it to control your magnification: it also indicates whether you are looking at content through optimal magnification or digital pmagnificaion. The number of articifically added zoomlevels for digital zoom can be controlled in PMA.UI, or even disabled altogether. | ||

+ | On mobile devices, //pinching// also works (use the pinch manoever to rotate your content, too!). | ||
