Hi all,
How can I detect if an ellipse shaped object is within boundaries of an
region?
MapBasic's geographic operation " objectA Entirely Within objectB"
always returns FALSE when object A is an ellipse and objectB is a
region.
The opposite operation "objectA Contains Entire ObjectB) results always
False when objectA is a region and objectB is an ellipse.
I noticed the problem in MapInfo 5.0 using MapBasic 5.0
You can verify this for yourself in MapInfo:
-Set cosmetic layer editable
-Draw a region
-Draw an ellips within the boundaries of the region
-Draw a rectangle within the boundaries of the region
-Open the mapBasic window
-In MapBasic window type:
Dim region as Object
Dim ellips as Object
Dim rect as object
-In mapper window select the region
-In MapBasic window type:
region = selection.obj
-In mapper window select the ellipse
-In MapBasic window type:
ellips = selection.obj
-In mapper window select the rectangle
-In MapBasic window type:
rect = selection.obj
-In MapBasic window type:
print (rect entirely within region)
print (ellips entirely within region)
The first print result = "T" (true)
The second printresult = "F" (false)
Is this a bug or what?
