TI attribute extensions for the node object.
| Enumerator | |
|---|---|
| TIVX_NODE_TARGET_STRING | Returns the target string corresponding to the node. |
| TIVX_NODE_TIMEOUT | Set/Query the node level timeout parameter. Read-Write. Can be written at initialization as well as at runtime. This timeout attribute affects the operation of the node CREATE and DELETE target kernel functions. Use a |
| TIVX_NODE_IS_TIMED_OUT | Query the node to see if it has timed out. Read-Only. Can be read at initialization as well as at runtime. Use a |
TI attribute extensions for the reference object.
| Enumerator | |
|---|---|
| TIVX_REFERENCE_TIMESTAMP | Returns the timestamp in micro-seconds corresponding to the given reference. |
| TIVX_REFERENCE_INVALID | Returns a boolean indicating whether or not a reference is invalid. |
| TIVX_REFERENCE_BUFFER_IS_ALLOCATED | Query the reference to see if the associated buffer has been allocated. Note that this is only applicable in the case that the buffer has been allocated by the framework. It does update if the buffer has been imported to or exported from the vx_reference. Read-Only. Can be read at initialization as well as at runtime. Use a |

| Enumerator | |
|---|---|
| TIVX_CONTEXT_NUM_USER_KERNEL_ID | Query the context number of user kernel ID's. Read-Only. Can be read at initialization as well as at runtime. Use a |
| TIVX_CONTEXT_NUM_USER_LIBRARY_ID | Query the context number of user library ID's. Read-Only. Can be read at initialization as well as at runtime. Use a |
TI attribute extensions for the image object.
| Enumerator | |
|---|---|
| TIVX_IMAGE_IMAGEPATCH_ADDRESSING | Query the imagepatch addressing structure from a vx_image. Read-Only. Can be read at initialization as well as at runtime. Use a |
| TIVX_IMAGE_STRIDE_Y_ALIGNMENT | Parameter allowing an application to query or set the stride Y alignment of a vx_image. By default, this value will be set to TIVX_DEFAULT_STRIDE_Y_ALIGN. Care must be taken to understand the requirements of the hardware which is consuming or producing the vx_image. Hardware which is being used via an OpenVX node has verification time errors thrown if the alignment is not in accordance with the requirements of the hardware, but alignment requirements of other hardware which is outside the scope of TIOVX (i.e., codecs) must be understood by the application developer and taken into consideration when creating the image consumed by that hardware. (For instance, the default value was originally chosen since this is a requirement of codec used on TI Jacinto devices) Read-Write. Can be read at any time, but only written to prior to the allocation of the buffer. Cannot be applied to subimages or images with subimages. If attempting to modify as a part of an object array, the exemplar itself shall be set rather than the elements of the object array Use a |
