Description

This function inquires about a specified setting associated with a Blob Analysis context or result buffer.

You can use MblobControl() to change a setting associated with a context or a result buffer.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameters

ContextOrResultBlobId

Specifies the identifier of a Blob Analysis context or result buffer.

InquireType

Specifies the type of setting about which to inquire.

See the Parameter associations section for possible values that can be specified.

UserVarPtr

Accepts the address of one of the following (see the Parameter associations section for specifics on which is expected):

MIL_DOUBLE
MIL_ID
MIL_INT
MIL_INT32
MIL_INT64

Specifies the address in which to write the requested information. Since the MblobInquire() function also returns the requested information, you can set this parameter to M_NULL.

Combination values for the following values of in-parameters: the values listed in For inquiring about features with two definitions (binary and grayscale).

The above-mentioned in-parameter values must be added to the following values. The above-mentioned out-parameter values are returned combined with the following values. In either case, the following values are used to set whether the results should be returned for the binary or grayscale version of the selected feature.

For feature parameters that have two definitions
Combination value	Description
M_BINARY	Selects the binary definition of the selected feature.
M_GRAYSCALE	Selects the grayscale definition of the selected feature.

the values listed in all the parameter association tables except For inquiring the system on which the result buffer or context is allocated, For inquiring about the global processing settings of a Blob Analysis context that cause results to be recalculated, For inquiring about a processing setting in a Blob Analysis result buffer.

You can add the following value to the above-mentioned values to determine the default value of an inquire type, regardless of the current value of the inquire type.

For inquiring the default value of an inquire type
InquireType		Description
	UserVarPtr - Possible values returned	Description
M_DEFAULT		Inquires the default value of the specified inquire type. (summarize) Inquires the default value of the specified inquire type. (more details...)
	UserVarPtr extra info	Data type info: Data type: address of a MIL_DOUBLE Data type info: Data type: address of a MIL_DOUBLE

For the following inquire types, the ContextOrResultBlobId parameter must specify a Blob Analysis result buffer.

For inquiring about a processing setting in a Blob Analysis result buffer
InquireType		Description
	UserVarPtr - Possible values returned	Description
M_INPUT_SELECT_UNITS +		Inquires the units in which the CondLow and CondHigh parameters of MblobSelect() expect the limits of the blob selection condition. SET (summarize) Inquires the units in which the CondLow and CondHigh parameters of MblobSelect() expect the limits of the blob selection condition. SET (more details...)
	UserVarPtr extra info	Data type info: Data type: address of a MIL_DOUBLE Data type info: Data type: address of a MIL_DOUBLE

	M_WORLD	Specifies that the limit values passed to MblobSelect() be interpreted in world units, with respect to the relative coordinate system. INFO
M_MAX_LABEL +		Inquires the maximum label value given to any included blob in the result buffer. Label values for blobs are generated when a call to MblobCalculate() is made. The maximum label value is not necessarily the same as the total number of blobs because some label values might not be used, depending on the blob's shape. One of the uses for obtaining the maximum label value is to determine if an 8 or 16-bit image buffer is needed for MblobDraw(). (summarize) Inquires the maximum label value given to any included blob in the result buffer. (more details...)
