Synopsis

Restore a camera or 3D draw calibration context from disk.

Syntax

MIL_ID McalRestore(

MIL_CONST_TEXT_PTR FileName,	//in
MIL_ID SysId,	//in
MIL_INT64 ControlFlag,	//in
MIL_ID *CalibrationIdPtr	//out

)

Description

This function restores a camera or 3D draw calibration context that was previously saved to a file, using McalSave() or McalStream(), and assigns it a MIL identifier.

This function can also restore the camera calibration context associated with a MIL image buffer (MIM) that was previously saved to a file, using MbufExport() with M_MIL_TIFF + M_WITH_CALIBRATION, and assign the context a MIL identifier. If you then associate this restored camera calibration context to the restored image buffer, the calibrated image will be in the same state as the previously saved image (at the moment it was saved). For more information, see the Saving and reloading a calibrated image subsection of the Camera calibration propagation section of Chapter 26: Calibrating your camera setup.

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 camera or 3D draw calibration context. The function handles (internally) the opening and closing of the file.

This parameter can be set to one of the following:

For specifying the file name and path
Value	Description
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.
MIL_TEXT("FileName") ¹	Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). Typically, camera and 3D draw calibration context files have an MCA extension. To specify a file on the remote computer (under Distributed MIL), prefix the specified file name string with "remote:///" (for example, "remote:///C:\mydirectory\myfile"). (summarize) Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). (more details...)

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 camera or 3D draw calibration 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().

ControlFlag

Specifies the function's control flag. This parameter must be set to the following value:

For specifying the function's control flag
Value	Description
M_DEFAULT	Sets the function's control flag to the default.

CalibrationIdPtr

Specifies the address in which to return the identifier of the camera or 3D draw calibration context. Since McalRestore() also returns the identifier, you can set this parameter to M_NULL.

Return value

The returned value is the identifier of the camera or 3D draw calibration context if the operation was successful; M_NULL if the operation failed.
