<div dir="ltr">Hi All,<div><br></div><div>I was trying to perform intersection on two feature classes (shape file format) using OGRLayer.Intersection(), but have problems making it work with C# bindings. I am not able to figure out on how to pass the arguments SWIGTYPE_p_GDALProgressFunc callback and OSGeo.OGR.SWIGTYPE_p_void callback_data. Can someone please help me figure out on how to handle these. I keep getting the error "Attempt to dereference null GDALProgressFunc". I am not sure what that means.</div>
<div><br></div><div style>Please share an example on how to call Intersection routine or some other routine which takes above mentioned argument types.</div><div style><br></div><div style>Thank you,</div><div><div>Dheeraj Reddy Mamidi<br>
