[mapguide-users] Rendering defect?

[Dave Wilson]

I don't think the issue is so much about the clipping, it's about the false border that's introduced. Users don't want a false border on the clipped polygon.

There are APIs in the rendering service for both clipped and unclipped rendering. RenderDynamicOverlay clips, while RenderMap doesn't. I'm not sure which one Fusion uses though. You can try manually issuing a RenderMap to see if you get the result you want. Using the un-clipped rendering carries a performance penalty.

Exactly, that's what I wanted to express - I'm not an native speaker
I want to be able to switch off that current behavior of MG
