Description

This function restores a metrology context that was previously saved to a file, using MmetSave() or MmetStream(). This function restores all the metrology context's settings and names that were in effect when the metrology context was saved.

If you had associated a camera calibration context with the template reference in your metrology context and you did not save it with the context, you must re-associate the camera calibration context, using MmetControl() with M_ASSOCIATED_CALIBRATION. Moreover, if you had previously set drawing control types, using MgraControl() with M_DRAW_..., you must reset them since they were not saved with the context.

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
FileName

Specifies the name and path of the file from which to restore the metrology context. The function handles (internally) the opening and closing of the file.

This parameter can be set to one of the following:

function map For specifying the file name and path
Click to summarizeValue Description
Click to summarize M_INTERACTIVE
[This is only applicable to Windows]

Opens the File Open dialog box from which you can interactively specify the drive, directory, and name of the file.
Click to summarize MIL_TEXT("FileName") 1

Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). Typically, metrology contexts have an MET extension.

To specify a file on a remote computer (under Distributed MIL), prefix the specified file name string with "remote:///" (for example, "remote:///C:\mydirectory\myfile").

1 If you are passing the value in a variable, don't enclose it in MIL_TEXT().

SysId

Specifies the system on which to restore the metrology context.

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

function map For specifying the system identifier
Click to summarizeValue Description
Click to summarize M_DEFAULT_HOST

Specifies the default Host system of the current MIL application.
Click to summarize MIL system identifier

Specifies a valid system identifier, previously allocated using MsysAlloc().
ControlFlag

Specifies whether to restore, from the metrology context, the camera calibration context associated with the template reference.

function map For specifying whether to restore the camera calibration context associated with the template reference
Click to summarizeValue Description
Click to summarize M_DEFAULT

Specifies that the camera calibration context is not restored.
Click to summarize M_WITH_CALIBRATION

Specifies that the camera calibration context is restored. In this case, the camera calibration context must have been previously saved with the context, using MmetSave() or MmetStream() with M_WITH_CALIBRATION.

The camera calibration information is restored from the same file as the metrology context. The camera calibration cannot be managed independently from the metrology context. When the metrology context is freed, the camera calibration is automatically freed as well.

ContextIdPtr

Specifies the address of the variable in which to write the metrology context identifier. Since MmetRestore() also returns the metrology context identifier, you can set this parameter to M_NULL. If allocation fails, M_NULL is written as the identifier.

Return value
The returned value is the metrology context identifier. If allocation fails, M_NULL is returned.
