|PanGazer – saving views|
PanGazer lets you snapshot (save) the current view as an image file. To do this, select the Snapshot current view ... menu item from the View menu or from the pop-up menu (or press the ‘s’ key): this will open the Windows file save dialog box for saving the image file.
Unlike a simple screenshot, the saved view (snapshot) includes metadata such as the effective lens focal length, camera tilt, and the location and bearing of the view. Therefore, a ‘flat’ saved view derived from a spherical image preserves available geometrical metadata so that (for example) moving the cursor over the image will show the correct bearing (or yaw) and tilt of the ‘camera’ at that point, and compass points and tilt angles can be overlaid on the image just as for the spherical source image.
Further, since the saved image includes the relevant metadata then if you then open the new image with PanGazer then any view of that image (for example, zoomed in) can also be saved and will also correctly propagate the metadata. Note, however, that angular position detail in the new image will only be correct if the zooming-in is on the centre of the image (e.g., by pressing ‘i’).
Images not created by PanGazer will similarly also show correct angular data provided they were not cropped, or if cropped they were cropped without changing the centre of the image and the lens information was updated to match.
