Selection symbol gets cut

Question

I am setting a selectionSymbol for my layer this way (iOS SDK v 10.2.5):

if let selectionSymbol = AGSPictureMarkerSymbol(image: selectionSymbolImg) {

selectionSymbol.offset = CGPoint(x: 0, y: 10)

layer.selectionSymbol = selectionSymbol

}

On the first picture you can see the expected result. However sometime when I select a point on the map the selection symbol gets cut, see second picture. So what's wrong with it? Have can I avoid this behavior? And how can I bring selected point to the front?

Ok, good. The dynamic rendering mode could not handle as many graphics as the static rendering mode in 10.2.x. So make sure performance is ok for the number of graphics that you are using. If performance becomes an issue there are some other workarounds you can try:

- putting selected graphics in a different graphics layer

- smaller selection symbol

Thanks! Tested for a while and seems the issue is gone with dynamic rendering mode.

I think this is a bug in our static mode graphics layer rendering. We render to tiles and with a bigger symbol like that for the selection symbol, it doesn't realize that it needs to draw it in multiple tiles. Can you try dynamic graphics layer rendering mode to confirm that?
