I want to derive a node a node that takes 3 input images and gives one output image. There is no in-built node present in DMIP library. So, I derived a SimpleNode_3_1 from "Node" class to take 3 inputs. But following trace messages are printed in trace file. Is this approach is correct? or we can't derive a node that takes 3 input nodes.
Trace to file Trace3node.txt started
Image 0012FE60 is being created with not good for DMIP buffer.
Image 0012FDB4 creation failed with code -1
Input port 0 does not exist in SimpleNode_3_1 02424E90 in iGraph 022ECB88
Input port 1 does not exist in SimpleNode_3_1 02424E90 in iGraph 022ECB88
Input port 2 does not exist in SimpleNode_3_1 02424E90 in iGraph 022ECB88
Output port 0 does not exist in SimpleNode_3_1 02424E90 in iGraph 022ECB88
Compilation aborted - free input in Graph 02424E30
Execution aborted - wrong status Normal of Graph 02424E30
Is it explicitely required to specify Input ports (Input port 0, port1 ,port2) and output port? If yes, then how do we specify them?
