Apply default zoom to Google Maps

[fred]

Hi,

In v13, the new locate image command can be customized.

Go to Preferences>Miscellaneous>Advanced>image_locate_service and replace the line with google map with:

google[Google Maps]=https://maps.google.com/?q=%lat%,%lon%&ll=%lat%,%lon%&z=7

Change the z=# to apply a zoom between 1 to 20.

Select an image file containing GPS coordinates to display the image toolbar. Customize and drag and drop the locate image command to this toolbar. I set the button to only display an icon.

TODO: I think we could improve this button making it disabled if the selected image doesn’t have GPS info. If someone wants to help. I guess it would use the evaluator.

Image LOCATE buttons are hidden by default if there's no GPS information; the ones in the submenu are an exception, which are only disabled.

You should be able to use IsEnabled() in the evaluator to use this to check for GPS, e.g. IsEnabled("Image LOCATE") should return true if GPS is available.

Note that Image LOCATE only hides/disables itself in the viewer, not when placed on lister toolbars. Checking if the selected file(s) contain GPS data each time the selection changes would be slow/expensive, while the image viewer already knows about the file it has loaded and displayed.

Locate image command

Context stuff won't work in the Lister itself, since determining whether a file has coordinates in it or not is an expensive operation. You could maybe do something with the evaluator, but by default it ignores Image LOCATE commands completely (wit…

Could I use @enableif with this button ?

Image LOCATE=google

How?

[lxp]

Yes. For example, this would create a button that works only on Sundays:

@enableif:=DatePart(Now(), "D")=="1"
Image LOCATE=google
