White Border On Background

A white border appears around background images as you go North of about 39 degrees. Lower than this and the background filles the entire screen. Does not seem to be source related.

The border appears on zoom levels 3 and greater in higher latitudes. It occurs on all servers - map and street. Just go to northern Canada and it may occur for you. Or, it may be my system.

While I was zooming around I received an exception error. I get these and other Microsoft generated overflow errors with sufficient frequency that I will have to reload the program. Unfortunately I cannot attach images and Bill Gates does not allow me to do a Copy of his error messages.

Hello,

Code: Select all

            ImageTile = New Bitmap(1792, HH)
            MapBackground.WLON = LonFromXMerc(X, Zoom)
            MapBackground.ELON = LonFromXMerc(X + 7, Zoom)
            MapBackground.NLAT = LatFromYMerc(Y, Zoom)
            MapBackground.SLAT = LatFromYMerc(Y + 5, Zoom)
            MapBackground.COLS = ImageTile.Width
            MapBackground.ROWS = ImageTile.Height

The background is a picture that corresponds to 7 x 5 tiles! The distortion that you observe is due to the projection that SBuilderX uses to display maps. Nothing is wrong I hope. The lat/lon that the mouse shows is correct even when you are at those northen latitudes.

Kind Regards,

Luis
