extract rotatted rectangle c#

[Vladimir_Drzik]

Hi Kumi

I'm not familiar with NI vision under C#, so I will just give you the steps I would take:

1. Extract the whole bounding rectangle of your rotated rectangle
2. Do a bitmap rotation according to the angle of the rotated rectangle. You have to use the inverse angle to make the bitmap oriented in the right direction.
3. Extract the center part of the rotated bitmap. The size of this part is equal to the dimensions of the original rotated rectangle

I can give you some code in LabVIEW if you can read it.

Hi Vladimir,

this is exactly the problem I have, but I need to do it in LabView. Do you have code that does this? I'm having troubles cutting the right size out after the rotation.

Thanks,

Hi Georg

Sorry to reply so late, I was too busy to do the example. Here you are.
