Detailed Description

This file show example of using basic PyTIOVX APIs to describe user/target kernel class and use it within an OpenVX graph.

See vx_tutorial_graph_image_gradients_pytiovx_uc.py for basic API usage.

The basic steps to define user/target class and use it with PyTIOVX tool

• Define a class for user/target kernel dervied from tiovx::node::Node base class
• Overide the constructor to explicitly specific the parameters and types
  • This allows the python to do basic syntax checking
• Overide the checkParams method to specify additional parameter checking if required
• Write the OpenVX use-case using PyTIOVX APIs
  • Use the user/target class when adding the user/target kernel to the graph
• Export the graph as C code or .jpg file

See source code of function vx_tutorial_graph_user_kernel_pytiovx_uc.make_my_graph() for detailed API usage for this example.
