Node: Border Modes

Detailed Description

Defines the border mode behaviors.

Border Mode behavior is set as an attribute of the node, not as a direct parameter to the kernel. This allows clients to set-and-forget the modes of any particular node that supports border modes. All nodes shall support VX_BORDER_UNDEFINED.

Data Structure Documentation

struct vx_border_t

Use with the enumeration VX_NODE_BORDER to set the border mode behavior of a node that supports borders.

If the indicated border mode is not supported, an error VX_ERROR_NOT_SUPPORTED will be reported either at the time the VX_NODE_BORDER is set or at the time of graph verification.

Definition at line 1729 of file vx_types.h.

Data Fields
vx_enum	mode	See vx_border_e.
vx_pixel_value_t	constant_value	For the mode VX_BORDER_CONSTANT, this union contains the value of out-of-bound pixels.

Enumeration Type Documentation

enum vx_border_e

The border mode list.

Enumerator
VX_BORDER_UNDEFINED	No defined border mode behavior is given.
VX_BORDER_CONSTANT	For nodes that support this behavior, a constant value is filled-in when accessing out-of-bounds pixels.
VX_BORDER_REPLICATE	For nodes that support this behavior, a replication of the nearest edge pixels value is given for out-of-bounds pixels.

Definition at line 1336 of file vx_types.h.

enum vx_border_policy_e

The unsupported border mode policy list.

Enumerator
VX_BORDER_POLICY_DEFAULT_TO_UNDEFINED	Use VX_BORDER_UNDEFINED instead of unsupported border modes.
VX_BORDER_POLICY_RETURN_ERROR	Return VX_ERROR_NOT_SUPPORTED for unsupported border modes.
