CenterPointReplacer: How generates the "Inside Point" feature?

https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/centerpointreplacer.htm

There are three options:

• Center point: Replaces the geometry of the feature with a point that is in the center of the feature's bounding box.
• Center of Gravity Point: Replaces the geometry of the feature with a point at the center of mass of the feature. Note that, depending on the feature’s shape, the resulting point may be far outside of the original feature.
• Inside Point: Replaces the geometry of the area feature with a point that is guaranteed to be inside the area.

I often see that the inside point is very close to the edge of the polygon but I've never seen a case where the point would not then overlap using the point on area overlayer. Are you able to share this particular geometry?

That's a very strange result indeed, would love to take a look at it too.

Maybe somebody from Safe can chime in about how the CenterPointReplacer works under the hood if you pick the InsidePoint option. Does it try CenterPoint and CenterOfGravity first and if both of those fall outside the polygon does it then pick "a" point inside?

Hello,

I would like to understand how the inside point is calculate exactly from the polygon by the CenterPointReplacer transformer.

Have you got answer for this issue ?
