Longitude display error. #49

Closed geomatixDeveloper closed 4 years ago

geomatixDeveloper commented 5 years ago

On Mapwingis there is a longitude display error, which alos seems to upset tile loading of background maps. It s present in 4.9.6.1 and in 5.0.1.0 Set Map1.ShowCoordinates=true The default latitude and longitude is degrees and minutes However using this default map set-up when the cursor is just in the west the values the map is displaying -ve minutes with positive degrees. I guess its a bug in the display conversion routine. Using W7 and VB6. You can see this easily if you display a background map and pan it to London UK which is on the Grenwich meridan. Then move the cursor slowly from right to left. It changes from Lng: 0° 00 ' to -1° 59' which is incorrect it should read -0° 01'. A similar bug seems to affect the tiles which are refreshed and loaded. The result is that tiles to the west are not updated properly and display in lo-res than those on the right. image

Thanks for letting us know. We will investigate this more. At the moment we have some problems loading any OSM tiles, we need to fix that first.

If this is still an issue with the latest release (https://github.com/MapWindow/MapWindow5/releases) could you create a new issue? For now, I close this old issue.
