Detailed Description

The type definitions required by OpenVX Library.

Macro Definition Documentation

◆ VX_DF_IMAGE

#define VX_DF_IMAGE	(	a,
		b,
		c,
		d
	)	((vx_uint32)(vx_uint8)(a) \| ((vx_uint32)(vx_uint8)(b) << 8U) \| ((vx_uint32)(vx_uint8)(c) << 16U) \| ((vx_uint32)(vx_uint8)(d) << 24U))

Converts a set of four chars into a uint32_t container of a VX_DF_IMAGE code.

Note: Use a vx_df_image variable to hold the value.

◆ VX_ENUM_BASE

#define VX_ENUM_BASE	(	vendor,
		id
	)	((vx_int32)(((vx_uint32)(vendor) << 20) \| ((vx_uint32)(id) << 12)))

Defines the manner in which to combine the Vendor and Object IDs to get the base value of the enumeration.

From any enumerated value (with exceptions), the vendor, and enumeration type should be extractable. Those types that are exceptions are vx_vendor_id_e, vx_type_e, vx_enum_e, vx_df_image_e, and vx_bool.

◆ VX_TYPE_MASK

#define VX_TYPE_MASK (0x000FFF00U)

A type mask removes the scalar/object type from the attribute. It is 3 nibbles in size and is contained between the third and second byte.

See also: vx_type_e

Typedef Documentation

◆ vx_action

typedef vx_enum vx_action

The formal typedef of the response from the callback.

See also: vx_action_e

◆ vx_bool

typedef vx_enum vx_bool

A formal boolean type with known fixed size.

See also: vx_bool_e

◆ vx_border_t

typedef struct _vx_border_t 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.

◆ vx_context

typedef struct _vx_context* vx_context

An opaque reference to the implementation context.

See also: vxCreateContext

◆ vx_delay

typedef struct _vx_delay* vx_delay

The delay object. This is like a ring buffer of objects that is maintained by the OpenVX implementation.

See also: vxCreateDelay

◆ vx_enum

typedef int32_t vx_enum

Sets the standard enumeration type size to be a fixed quantity.

All enumerable fields must use this type as the container to enforce enumeration ranges and sizeof() operations.

◆ vx_graph

typedef struct _vx_graph* vx_graph

An opaque reference to a graph.

See also: vxCreateGraph

◆ vx_image

typedef struct _vx_image* vx_image

An opaque reference to an image.

See also: vxCreateImage

◆ vx_imagepatch_addressing_t

typedef struct _vx_imagepatch_addressing_t vx_imagepatch_addressing_t

The addressing image patch structure is used by the Host only to address pixels in an image patch. The fields of the structure are defined as:

dim - The dimensions of the image in logical pixel units in the x & y direction.
stride - The physical byte distance from a logical pixel to the next logically adjacent pixel in the positive x or y direction.
scale - The relationship of scaling from the primary plane (typically the zero indexed plane) to this plane. An integer down-scaling factor of \( f \) shall be set to a value equal to \( scale = \frac{unity}{f} \) and an integer up-scaling factor of \( f \) shall be set to a value of \( scale = unity * f \). \( unity \) is defined as VX_SCALE_UNITY.
step - The step is the number of logical pixel units to skip to arrive at the next physically unique pixel. For example, on a plane that is half-scaled in a dimension, the step in that dimension is 2 to indicate that every other pixel in that dimension is an alias. This is useful in situations where iteration over unique pixels is required, such as in serializing or de-serializing the image patch information.

vxMapImagePatch

Note
For VX_DF_IMAGE_U1 images it is defined that stride_x == 0 since it is less than one byte. The least significant bit (bit number 0, value 1) in the first byte in the image, is the left-most pixel in the upper left corner, i.e. origo. A VX_DF_IMAGE_U1 image always start on a byte boundary and each row has a stride_y that is a multiple of whole bytes, which means padding bits of undefined value may be present at the end of each row. Imagepatches can only be accessed at a multiple of eight pixels: the x-coordinate must be a multiple of eight. Individual pixel access is also different: the byte at the imagepatch-calculated pointer value is a collection of eight pixels. Each byte can then be masked with the bit-mask 1 << (x % 8) to get individual pixel values (shifted x times). See sub_image_access for an example.

◆ vx_kernel

typedef struct _vx_kernel* vx_kernel

An opaque reference to the descriptor of a kernel.

See also: vxGetKernelByName; vxGetKernelByEnum

◆ vx_kernel_deinitialize_f

typedef vx_status(VX_CALLBACK * vx_kernel_deinitialize_f) (vx_node node, const vx_reference *parameters, vx_uint32 num)

The pointer to the kernel deinitializer. If the host code requires a call to deinitialize data during a node garbage collection, this function is called if not NULL.

Parameters

[in]	node	The handle to the node that contains this kernel.
[in]	parameters	The array of parameter references.
[in]	num	The number of parameters.

◆ vx_kernel_f

typedef vx_status(VX_CALLBACK * vx_kernel_f) (vx_node node, const vx_reference *parameters, vx_uint32 num)

The pointer to the Host side kernel.

Parameters

[in]	node	The handle to the node that contains this kernel.
[in]	parameters	The array of parameter references.
[in]	num	The number of parameters.

◆ vx_kernel_image_valid_rectangle_f

typedef vx_status(VX_CALLBACK * vx_kernel_image_valid_rectangle_f) (vx_node node, vx_uint32 index, const vx_rectangle_t *const input_valid[], vx_rectangle_t *const output_valid[])

A user-defined callback function to set the valid rectangle of an output image.

The VX_VALID_RECT_CALLBACK attribute in the vx_meta_format object should be set to the desired callback during user node's output validator. The callback must not call vxGetValidRegionImage or vxSetImageValidRectangle. Instead, an array of the valid rectangles of all the input images is supplied to the callback to calculate the output valid rectangle. The output of the user node may be a pyramid, or just an image. If it is just an image, the 'Out' array associated with that output only has one element. If the output is a pyramid, the array size is equal to the number of pyramid levels. Notice that the array memory allocation passed to the callback is managed by the framework, the application must not allocate or deallocate those pointers.

The behavior of the callback function vx_kernel_image_valid_rectangle_f is undefined if one of the following is true:

One of the input arguments of a user node is a pyramid or an array of images.
Either input or output argument of a user node is an array of pyramids.

Parameters

[in,out]	node	The handle to the node that is being validated.
[in]	index	The index of the output parameter for which a valid region should be set.
[in]	input_valid	A pointer to an array of valid regions of input images or images contained in image container (e.g. pyramids). They are provided in same order as the parameter list of the kernel's declaration.
[out]	output_valid	An array of valid regions that should be set for the output images or image containers (e.g. pyramid) after graph processing. The length of the array should be equal to the size of the image container (e.g. number of levels in the pyramid). For a simple output image the array size is always one. Each rectangle supplies the valid region for one image. The array memory allocation is managed by the framework.

Returns: An error code describing the validation status on parameters.

◆ vx_kernel_initialize_f

typedef vx_status(VX_CALLBACK * vx_kernel_initialize_f) (vx_node node, const vx_reference *parameters, vx_uint32 num)

Parameters

[in]	node	The handle to the node that contains this kernel.
[in]	parameters	The array of parameter references.
[in]	num	The number of parameters.

◆ vx_kernel_validate_f

[in]	parameters	The array of parameters to be validated.
[in]	num	Number of parameters to be validated.
[in]	metas	A pointer to a pre-allocated array of structure references that the system holds. The system pre-allocates a number of vx_meta_format structures for the output parameters only, indexed by the same indices as parameters[]. The validation function fills in the correct type, format, and dimensionality for the system to use either to create memory or to check against existing memory.

Returns: An error code describing the validation status on parameters.

◆ vx_meta_format

typedef struct _vx_meta_format* vx_meta_format

This object is used by output validation functions to specify the meta data of the expected output data object.
