Restore a registration context or result buffer from disk.

Syntax

AIL_ID MregRestore(
    AIL_CONST_TEXT_PTR FileName,             //in
    AIL_ID             SystemId,             //in

)

Description

This function restores a registration context or result buffer that was previously saved to a file, using MregSave or MregStream. This function restores all of the registration context's or result buffer's settings that were in effect when it was saved. Note that you can only restore an M_STITCHING_RESULT result buffer.

After restoring the registration context, you should check if the operation was successful, using MappGetError or by verifying that the registration context identifier returned is not M_NULL (or nullptr ifM_UNIQUE_ID was specified).

When the restored registration context is no longer required, release it usingMregFreeunless M_UNIQUE_ID was specified during restoration; if M_UNIQUE_ID was specified, the smart identifier manages the restored registration context's lifetime and you must not manually free it.

Parameters

FileName (in, AIL_CONST_TEXT_PTR)

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

For specifying the file name and path

Value	Description
M_INTERACTIVE	Opens the File Open dialog box from which you can interactively specify the drive, directory, and name of the file.
"FileName"	Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). Typically, registration context files have an MREG extension.

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

SystemId (in, AIL_ID)

Specifies the system on which to restore the registration context.

For specifying the system identifier

Value	Description
M_DEFAULT_HOST	Specifies the default Host system of the current Aurora Imaging Library application.
System identifier	Specifies a valid system identifier, previously allocated using MsysAlloc.

ControlFlag (in, AIL_INT64)

Reserved for future expansion and must be set to M_DEFAULT.

ContextOrResultIdPtr *(out, AIL_ID)

Specifies the address of the variable in which to write the registration context identifier or specifies the data type that the function should use to return the registration context identifier.

For retrieving the identifier or specifying how to return it

Value	Description
M_NULL	Specifies that you will use this function's return value to obtain the identifier of the allocated registration context; in this case, a standard Aurora Imaging Library identifier of type AIL_ID is returned.
M_UNIQUE_ID	Specifies that you will use this function's return value to obtain the identifier of the allocated registration context; in this case, an Aurora Imaging Library smart identifier of type _AIL_UNIQUE_REG_ID_is returned instead of a standard Aurora Imaging Library identifier.This setting is only available when using C++11 (or later).An Aurora Imaging Library smart identifier manages the lifespan of the Aurora Imaging Library object it owns (similar to a std::unique_ptr). Note, you can use an Aurora Imaging Library smart identifier as though it were a standard Aurora Imaging Library identifier, except that you cannot use it to manually free the registration context (it is freed automatically). For more information, see Aurora Imaging Library smart identifiers.
Address in which to write the EDOF registration context identifier	Specifies the address of an AIL_ID in which to write the identifier of the restored EDOF registration context.

If restoration fails, M_NULL is written as the identifier. | | Address in which to write the EDOF result buffer identifier | Specifies the address of an AIL_ID in which to write the identifier of the restored EDOF result buffer.

If restoration fails, M_NULL is written as the identifier. | | Address in which to write the HDR registration context identifier | Specifies the address of an AIL_ID in which to write the identifier of the restored HDR context.

If restoration fails, M_NULL is written as the identifier. | | Address in which to write the stitching registration context identifier | Specifies the address of an AIL_ID in which to write the identifier of the restored stitching context.

If restoration fails, M_NULL is written as the identifier. | | Address in which to write the stitching result buffer identifier | Specifies the address of an AIL_ID in which to write the identifier of the restored stitching result buffer.

If restoration fails, M_NULL is written as the identifier. |

Return Value

Type: AIL_ID

The returned value is the registration context identifier either as a standard identifier (AIL_ID) or a smart identifier (AIL_UNIQUE_REG_ID). If restoration fails, M_NULL is returned (or nullptr ifM_UNIQUE_ID was specified).
