HD View. Web page screen capture of Microscoft HD View which is used to smoothly display the gigapixel images online. The scale bar shows 500 μ m and changes as the user zooms in and out of the image (or resizes the browser window). The “Save Specific View” button displays a URL that can be copied and returns the view to the location on the large image and zoom level currently displayed. Buttons in the top-right have the following functions— Hand: translate the image view; Line: toggle between the following tone adjustments: no adjustment (horizontal line), exposure only adjustment (diagonal line), compress or expand the dynamic range as necessary (curve); Grid: toggle between auto lens and fisheye lens (this should be left as the grid icon, auto lens); Fullscreen: toggle between normal window and fullscreen (scale bar and “Save Specific View” button are not visible in fullscreen); Home: return to the fully zoomed out view, so the entire image is visible in the browser window; Magnifying glass: zoom in and out of the image. With a scroll wheel mouse, one can zoom into and out of a place on the image by scrolling the wheel forwards or backwards while the mouse is over the image.
