This allows the API to implement animated zoom transitions even for custom Projections, scaling the viewport from 1x to 2x. This also allows the API to project coordinates once and simply bit shift the projected coordinates on zoom, improving performance. > Thank you for any help. > Cheers Ben > -- > You received this message because you are subscribed to the Google Groups > "Google Maps JavaScript API v3" group. > To post to this group, send email to > [email protected]. > To unsubscribe from this group, send email to > [email protected]<google-maps-js-api-v3%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/google-maps-js-api-v3?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
