The Settings menu lets you change settings that apply to all
windows. These are:
Hide all status and overlays – this overrides the individual
Status and Overlays settings described below for all views. If checked
neither status nor overlays are displayed in any view. Use the
Space Bar or pop-up menu to temporarily toggle between ‘hide all’
and ‘show selected items and overlays’ for the current view. Changing
this setting resets all views to match the new setting.
Status display – lets you customize the status shown
in the window (‘dynamic’ status, which might alter as you change
the view or move the mouse, is shown at top right and ‘static’ status,
referring to the loaded image, is shown at bottom right); scroll
down to see example screenshot with some status.
Note that the status information is only shown if there is room
for it in the current window or image display (that is, if the status
information would be wider than half the width available or would
be taller than half the height available then it is not shown) .
The dynamic status options refer to the current view;
by default, only the first three are shown. The options are:
- Show view coverage – this indicates the extent of the view.
The first number shown is the current pel (pixel) ratio; for example,
if the pel ratio is 200% then each pel in the original image has
been extrapolated to 2×2 pels on-screen.
If the image is 360° or has a known 35mm-equivalent focal length
then the equivalent focal length of the view is shown next (e.g.,
if ‘100mm equivalent’ is shown then the view appears as though taken
with a 100mm lens on a 35mm film or full-frame digital camera).
The final part of the view coverage line comprises the apparent angles
of view in X and Y (horizontal and vertical) of the displayed image.
- Show view yaw and pitch – this shows the yaw (left-to-right
angle from the image centre) and pitch (bottom-to-top angle from
the image centre) of the current view; that is, where the ‘camera’
is pointing relative to the centre of the image.
If the bearing of the centre of the image is known (see the Setting North page) then the compass point and bearing of the view is shown
instead of the yaw, and similarly if the position of the horizon
is known (as in a spherical panorama or an image created from one)
then the pitch is shown as the tilt from the horizon (positive is
up).
- Show cursor yaw and pitch – if the mouse position (cursor
arrow) is over the displayed image this shows its yaw (left-to-right
angle from the image centre) and pitch (bottom-to-top angle from
the image centre).
If the bearing of the centre of the image is known (see the Setting North page) then the compass point and bearing of the mouse position
is shown instead of the yaw, and similarly if the position of the
horizon is known (as in a spherical panorama or an image created
from one) then the pitch is shown as the tilt from the horizon (positive
is up).
- Show enhancement values – this shows values of all the view enhancements if any enhancement is in use (is non-zero).
- Show performance statistics – this shows the amount of memory
explicitly allocated by PanGazer and also (if 1 ms or more) the time
taken (in seconds) to render the last image along with the corresponding
frame rate (frames per second).
The static status options describe the source image and
are only shown if the requested information is available, i.e., is
in the Exchangeable image file (Exif) or other metadata. The default
for these status settings is to show the status. The options are:
- Show exposure settings – shows the settings used to capture
the image (shutter speed, aperture, ISO sensitivity, and EV [Exposure
Value] bias if available and non-zero), and also indicates if the
flash fired.
- Show lens data – shows the lens focal length (if available).
Also, if the 35mm equivalent is available this shows that value together
with the diagonal angle of view of the image and the visual magnification
factor. The latter is the human angle of attention (assumed to be
54°) divided by the diagonal angle of view of the lens.
- Show camera geolocation and attitude – shows the latitude,
longitude, and GPS altitude of the device used when the image was
captured, and the bearing and tilt of the centre of the image (camera
attitude).
- Show image time and date – shows the original time and date
of image capture (usually in local time) and also the UTC timestamp
(if known).
- Show image size – shows the X and Y dimensions of the image
in pels, its horizontal and vertical Angles Of View, and its file
size.
- Show camera data – shows the lens crop factor (focal length
multiplier), if it can be calculated, and the camera make and model.
- Show image description – shows the image description, or if
none the full path and file name of the image (the window’s title
bar shows the image’s file name, with underscores treated as blanks).
- Show image Copyright – shows the image’s Copyright text.
Overlays – lets you turn on or off information that augments
the view (see the
Overlays page for details):
- Show compass points – if the direction of view is known (that
is, North has been set – see the
Setting North page) then compass points (N, E, SW, etc.) will be
overlaid at the top of the view. This setting is on by default.
- Show North line – if the direction of view is known and the
North (N) compass point is shown at the top of the view then
the North line is overlaid on the view. All points on the line are
due North of the camera. This setting is off by default but will
be set on if you Set North.
- Show tilt angles – if the tilt of the view is known the tilt
angles will be shown overlaid at the left edge of the view. This
setting is off by default.
If the Image Geography dialog is open then both overlays will
be shown (if valid values are available/have been applied), independent
of these settings. In addition, Show compass points will be
set if you use the Set North pop-up menu option and similarly
Show tilt angles will be set if you choose Set horizon.
Measurement units – selects the units used when elevations
are displayed. Here you can choose any or all of Metric, Statute
(customary), or Nautical units. By default, Metric will be used.
This sub-menu self-orders; when you uncheck an item it is moved
to the bottom of the list and when you check an item it is moved
above any unchecked items. This lets you control the order in which
units are displayed (also, the top item is always selected so elevations
can always have units).
Statute and Nautical units both use feet for elevations; both units
are offered to keep the selection consistent with MapGazer.
Coordinate formats – changes the format used for displaying
Latitude and Longitude; the formats available are:
- degrees°minutes′seconds″ (this is the default)
- degrees°minutes
- decimal degrees with 5 or 6 fractional digits
- UTM (Universal Tranverse Mercator).
Please see the Coordinate formats page for for details and examples.
Initial zoom on load – this sets the preferred zoom when
a new image is loaded:
- Minimum zoom – sets the zoom to the minimum available.
- Default zoom – sets the zoom to the default for the image,
which will be derived from image metadata if possible.
- 100% zoom – sets the zoom so that the pel (pixel) ratio will
be 100% (that is, each pel in the original image is represented by
one pel on-screen).
- Maximum zoom – sets the zoom so that the pel (pixel) ratio
will be 200%.
For more details, see the zoom level page.
Note that the initial zoom is only used when an image is first
loaded; if you close PanGazer then reopen it without specifying an
image then the view (including the zoom) last seen will be presented.
Note also that the requested initial zoom might not be possible
(especially for low-resolution or small images). In this case the
best zoom match available will be used.
Console settings – changes the console and diagnostic
settings:
- Show console – displays a console window; this is primarily
used for viewing error messages and diagnostics – if some action
does not work as expected it may be helpful to turn the console on
and check it for messages on retrying the action.
- Show extra diagnostics – displays more detailed diagnostics
on the console.
- Show received messages – displays each Windows message as
it is received by PanGazer; this setting is quite verbose and will
slow the normal operation of PanGazer.
All the above settings are saved in a file (PanGazer.ini) provided
that the folder containing PanGazer.exe is writable (if not, PanGazer
will use the Windows default User folder). Settings saved also include
details of the image and viewpoint last viewed, the current enhancement
values, the last-loaded image file folder, and the screen position
of the last-viewed window, etc. Settings are only saved for the
last-viewed window (view).
