Global Mapper Pro

Why is GM v20.1 ECW display performance much less responsive than previous versions?

Previous versions were very quick to redraw when panning and zooming ECW images. With version 20.1 I get the spinning circle a lot.

    Hope this is fixed in the v21 release.

    Hello,

    I suggest that you contact Blue Marble Support directly about this via email (geohelp@bluemarblegeo.com) if you are still seeing this problem in Global Mapper 21.0. Please provide a detailed description of your workflow, and an ECW file that exhibits slow performance when panning and zooming.

    We updated the library we use to read ECW files back in April. That update is in Global Mapper 21. I am not sure if it was also added to Global Mapper 20.1 in a minor version update also.

    Cheers,
    Bob

    Version 21.0 is a lot better than v20.1, but when zoomed way in it is not as quick as v17.2.
