The gnomonic projection


You can change the aspect ratio of a view window in two ways:

  • You can explicitly set the aspect ratio of the window using the Aspect Ratio dialog; to open this, select Window → Set aspect ratio (or press ‘a’).

  • If the image being viewed is not a 360 image (or View image as 360 has been turned off), you can select Fit aspect ratio from the pop-up menu or the Window menu; this will change the aspect ratio of the window to match that of the image, and zoom the image to fill the window.20191007-aspect-ratio.jpg

Aspect Ratio dialog

Aspect Ratio dialog

The Aspect Ratio dialog shows the current aspect ratio of the window and also lets you enter X and Y values to set your desired aspect ratio.

When entering X and Y values, both must be positive whole numbers, e.g., 16 and 9 to set a 16:9 ratio for X:Y. Once a valid X and Y have been entered, click ‘Apply’ to change the shape of the window immediately – PanGazer will set the requested aspect ratio while maintaining approximately the same window area, constrained by the size of the screen, etc.

Once a new aspect ratio has been applied you can click ‘Snapshot’ to save an image of the new view.

The other buttons available are:

‘Swap XP’ – this exchanges the X and Y values (switches portrait to landscape, or vice versa).

‘Reset’ – this resets the aspect ratio to the aspect ratio of the view when the dialog was opened.

‘Done’ – this applies the X and Y values then closes the dialog.

‘X’ (close) – closes the dialog without applying any changes.
