How to Use the Blob Function BlobGetConvexPoints in Visual Basic

Question

I want to know if and how I could use the Question/fr/glossaire/5293-Blob">Blob-​function BlobGetConvexPoints in Visual Basic.

Résponse

According to the documentation there are two arrays which should return the x and y values for the points. The two parameters are given by reference in the function. However in Visual Basic you have to give the function the first element of this array, not the array itself!

Here a short example how to do it:

Dim aX(100) As Long
Dim aY(100) As Long
BlobGetConvexPoints BlobHandle, I, aX(0), aY(0)
