+ | Use the arrow keys on your keyboard to move around | ||
+ | {{ ::viewport_panning1.png?direct&400 |}} | ||
+ | |||
+ | Click on the left mouse button, and move the mouse around, to move the slide around, too. | ||
+ | |||
+ | {{ ::viewport_panning2.png?direct&400 |}} | ||
+ | |||
+ | If you want to navigate somewhere quick, click anywhere in the overview image to immediately jump to that particular area at the current magnification. | ||
+ | |||
+ | {{ ::viewport_panning3.png?direct&400 |}} | ||
+ | |||
+ | If you want to rotate a slide, use Alt + mouse movements. Alternatively, use the rotation widget in the bottom left of the screen for simpler mouse control, or to enter very precise rotation angles. | ||

- | ==== Color control ==== | + | The thumbnail widget has a special button that allows you to track your progress throughout a slide: |
+ | |||
+ | {{ ::viewport_tracking.png?direct&200 |}} | ||
+ | |||
+ | Once enabled, a gray overlay covers your slide's thumbnail, with pieces of it gradually disappearing, as you start navigating your side. The zoomlevel at which you inspect a specific region of interest, influences the outline color in the tracking screen. | ||
+ | |||
+ | {{ :viewport_tracking2.png?direct&400 |}} | ||
+ | |||
+ | This kind of tracking is instantaneous and ad-hoc. When you close the viewport, it disappears, and its history is not logged. If you're interested in tracking viewing operations over time and across your use population, you should have a look at the [[heatmap]] functionality instead. | ||
+ | ==== Color correction ==== | ||
+ | |||
+ | The default PMA.UI representation in PMA.core shows a color correction widget in the top-right corner of the viewport. | ||
+ | |||
+ | {{ ::viewport_color_correction.png?direct&400 |}} | ||
+ | Use it to control brightness, contrast, and gamma correction. | ||
