LoadSettingsFromFile Method

Summary

Loads settings from a file.

Syntax

C++

public virtual void LoadSettingsFromFile( 
   string sourceFile, 
   CaptureSettings flags 
)

Public Overridable Sub LoadSettingsFromFile( _ 
   ByVal sourceFile As String, _ 
   ByVal flags As Leadtools.Multimedia.CaptureSettings _ 
)

public: 
virtual void LoadSettingsFromFile(  
   String^ sourceFile, 
   Leadtools.Multimedia.CaptureSettings flags 
)

Parameters

sourceFile
The file containing the saved settings to load.

flags
The settings flags specifying which settings to load.

Remarks

This reconstructs the capture configuration based on the settings loaded from the specified file. See the CaptureSettings enumeration for settings options. The capture object settings can be saved to a file by calling SaveSettingsToFile. The capture object settings can be saved to a stream by calling SaveSettingsToStream. Settings saved to a stream can be loaded using LoadSettingsFromStream.
