Description

This function restores a SureDotOCR context that was previously saved to a file, using MdmrSave() or MdmrStream(). This function restores all of the context's settings (including font and string model settings) that were in effect when the context was saved. A restored context is not preprocessed; therefore, you must call MdmrPreprocess() before performing a read with MdmrRead().

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 SureDotOCR context. The function handles (internally) the opening and closing of the file. For easier use with other Matrox Imaging software products, files for SureDotOCR contexts should use the MDMR file extension. Predefined SureDotOCR context files are typically distributed with MIL and can be found in a local folder (for example, "C:\Program Files\Matrox Imaging\contexts\").

Set this parameter to one of the values below:

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 a 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 SureDotOCR context file (for example, "C:\mydirectory\MySweetSweetContext.mdmr"). Typically, SureDotOCR context files have an MDMR extension.

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

(summarize)

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

SysId

Specifies the identifier of the system on which to restore the SureDotOCR context.

Set this parameter to one of the values below:

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

Reserved for future expansion and must be set to M_DEFAULT.

ContextDmrIdPtr

Specifies the address of the variable in which to write the SureDotOCR context identifier. Since this function also returns the context identifier, you can set this parameter to M_NULL. If this fails, M_NULL is written as the identifier.

Return value
The returned value is the SureDotOCR context identifier. If this fails, M_NULL is returned.
