Synopsis

Allocate a Blob Analysis context.

Syntax

MIL_ID MblobAlloc(

MIL_ID SysId,	//in
MIL_INT64 ContextType,	//in
MIL_INT64 ControlFlag,	//in
MIL_ID *ContextBlobIdPtr	//out

)

Description

This function allocates a Blob Analysis context. A Blob Analysis context contains all the information necessary to perform an MblobCalculate() operation, including global processing settings, and the blob features to calculate. Immediately after allocation, the context has only a few features enabled for calculation (for example, a blob's area). Use MblobControl() to enable addition features for calculation. When the context is no longer required, release it, using MblobFree().

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

SysId INQ

Specifies the system on which to allocate the context.

This parameter should be set to one of the following values:

For specifying the system
Value	Description
M_DEFAULT_HOST	Specifies the default Host system of the current MIL application.
MIL system identifier	Specifies a valid system identifier, previously allocated using MsysAlloc().

ContextType

Reserved for future expansion. This parameter must be set to M_DEFAULT.

ControlFlag

Reserved for future expansion. This parameter must be set to M_DEFAULT.

ContextBlobIdPtr

Specifies the address of the variable in which to write the identifier of the Blob Analysis context. If allocation fails, M_NULL is returned. Since the MblobAlloc() function also returns the context's identifier, you can set this parameter to M_NULL.

Return value

The returned value is the Blob Analysis context's identifier if the allocation is successful. If allocation fails, M_NULL is returned.

Remark

The prototypes of functions in the Mblob module changed as of MIL 10 PP2. For C applications, by default the original prototypes are used to ensure backward-compatibility. To use the updated prototypes, add #define M_USE_OLD_MBLOB_API_IN_C 0 before including mil.h. For information about the original API for the Mblob module refer to the MIL 10 PP1 documentation, available online to registered users at https://www.matrox.com/imaging/en/products/software/mil/documentation/.
