Function Documentation

show_image_attributes()

void show_image_attributes

(

vx_image

image

)

Show attributes of previously created image.

This function queries the vx_image image for its number of nodes, number of parameters, state, performance, reference name and reference count then prints this information.

Parameters

image

[in] Previouly created image object

• Query image attributes.

Queries image for width, height, format, planes, size, space, range, range and memory type.

show_graph_attributes()

void show_graph_attributes

(

vx_graph

graph

)

Show attributes of previously created graph.

This function queries the vx_graph graph for its number of nodes, number of parameters, state, performance, reference name and reference count then prints this information.

Parameters

graph

[in] Previouly created graph object

• Query graph attributes.

Queries graph for number of nodes, number of parameters, state and performance

  /
vxQueryGraph(graph, (vx_enum)VX_GRAPH_NUMNODES, &num_nodes, sizeof(vx_uint32));
vxQueryGraph(graph, (vx_enum)VX_GRAPH_NUMPARAMETERS, &num_params, sizeof(vx_uint32));
vxQueryGraph(graph, (vx_enum)VX_GRAPH_STATE, &state, sizeof(vx_enum));
vxQueryGraph(graph, (vx_enum)VX_GRAPH_PERFORMANCE, &perf, sizeof(vx_perf_t));

show_node_attributes()

void show_node_attributes

(

vx_node

node

)

Show attributes of previously created node.

This function queries the vx_node node for its status, number of parameters, performance, reference name and reference count then prints this information.

Parameters

node	[in] Previouly created graph object

• Query node attributes.

Queries node for number of status, number of parameters and performance

  /
vxQueryNode(node, (vx_enum)VX_NODE_STATUS, &status, sizeof(vx_status));
vxQueryNode(node, (vx_enum)VX_NODE_PARAMETERS, &num_params, sizeof(vx_uint32));
