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 which MIL system’s documentation you should use in its place and any possible differences.
Parameters
This function is not supported on the selected boards.
This function reference has not been updated for the selected MIL system. To show the content of this page, choose a second MIL system; refer to the MIL system's release note to see which MIL system’s documentation to choose and any possible differences.
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.

For the following inquire types, the ContextOrResultBlobId parameter can specify a Blob Analysis context. The following features have two different definitions: a binary definition, where all pixels are considered equal, and a grayscale, where pixels are weighted by their value in the gray image (the grayscale version is much slower to calculate). If you do not provide a grayscale image, only the binary version can be calculated. If you do provide a grayscale image, both versions are calculated.
