| + | 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. | ||
| + | |||
| + | {{ ::viewport_zooming2.png?direct&200 |}} | ||
| + | |||
| + | 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. | ||
| + | |||
| + | {{ ::viewport_zooming3.png?direct&200 |}} | ||
| + | |||
| + | On mobile devices, //pinching// also works (use the pinch manoever to rotate your content, too!). | ||
| + | |||
| + | ==== Thumbnails and labels ==== | ||
| + | |||
| + | Associated images are images that are part of the whole slide image data package, and provide additinal information about the slide. Examples include a thumbnail image, a scan map, or a label image. The first and the latter of this list are automatically added to the right of the viewport, if they are available. | ||
| + | |||
| + | {{ ::viewport_associates.png?direct&400 |}} | ||
| + | |||
| + | The label image can be rotated as needed. Clicking on it brings up the image in a separate viewing window. | ||
| + | |||
| + | The thumbnail has a blue rectangle drawn on it to indicate the currently viewed region of interest. This widget is a mini-browser in its own right: clicking anywhere on the thumbnail moves the current viewport to that particular area on the slide. The blue rectangle itself can be dragged around to a new location, too. | ||
| + | |||
| + | For smaller specimens like (needle) biopsies, the thumbnail can be enlarged so to easier identify individual objects on the slide. | ||
| + | |||
| + | [[https://realdata.pathomation.com/custom-panels-and-functionality-in-pma-studio/|Thumbnails, label images, and associated images in general can also be requested and presented individually]]. | ||

| ==== Fluorescent content ==== | ==== Fluorescent content ==== | ||
| + | |||
| + | When your slide contains one or more fluorescent color channels, a separate widget appears in the left-hand side of the viewport to allow controls over there. | ||
| + | |||
| + | {{ ::fluo1.png?direct&400 |}} | ||
| + | |||
| + | Names of channels are copied from the original file format, where possible. | ||
| + | |||
| + | You can control the visibility range of each channel individually through the scrollbar underneath each channel. | ||
| + | |||
| + | {{ ::fluo2.png?direct&400 |}} | ||
| + | |||
| + | Color ranges are supported both in 8 bit and 16 bit. Version 2.0.0 only supports 8 bit channels, which sometimes lead to color bleading. This was resolved in [[what_s_new_in_version_2.0.1|version 2.0.1]] and higher. | ||
| + | |||
| ==== Z-stacked content ==== | ==== Z-stacked content ==== | ||
| + | Similar to fluorescent slides; when a slide turns out to contain mutliple planes / stacks, a new widget appears automatically in the left-hand side of the viewport, allowing the end-user to navigate through the various layers. | ||
| + | |||
| + | {{ ::viewport_zstack.png?direct&200 |}} | ||
| + | We have a [[https://realdata.pathomation.com/blur-detection-in-z-stacks/|blog article on how you can analyze a z-stack]] to artifically compose a new slide that contains the sharpest tile at each position from the slide. | ||
