I add bitmaps as pointshapes with a rotation angle by doing what is suggested in this post: [Rotated Points and Text](https://community.thinkgeo.com/t/rotated-points-and-text/401/4)

The bitmap and rotation of that bitmap show up on the map fine, but for some reason the zoom in/out no longer works. Panning works fine, but zoom in/out seem to be disabled. I’m not getting any exceptions thrown. It’s only AFTER I add a bitmap.

Any ideas what could cause this?

Thanks.

Update: so it’s not just the bitmap, it’s when I add any feature to the layer.

This is an InMemoryFeatureLayer that I’m adding features to. The zoom works fine when adding ponits/shapes/etc. to the trackshapelayer.

Hi Dan,

Please try to rebuild index after you modify the feature.

If that don’t works, could you please upload a sample so we can look into it?

Regards,

Ethan

Hi Dan,

That’s strange to fix it by restart your computer, if you met any update later please let us know.
