Public Methods

Method	Description
Convert ( uint format ) : Image	Image format conversion. refer to the documentation for supported image formats The converted image size may be rounded (up) due to format constraints. See Image.FourCC for how to get the fourCC code.
Dispose ( ) : void	Release resources held by this object
FourCC ( char c0, char c1, char c2, char c3 ) : uint	Get FourCC code from four chars See FourCC.org for more information on FourCC. For information on format supported by zbar see: http://sourceforge.net/apps/mediawiki/zbar/index.php?title=Supported_image_formats
Image ( ) : System	Create/allocate a new uninitialized image Be aware that this image is NOT initialized, allocated. And you must set width, height, format, data etc...
Image ( System image ) : System	Create image from an instance of System.Drawing.Image The converted image is in RGB3 format, so it should be converted using Image.Convert() before it is scanned, as ZBar only reads images in GREY/Y800
ToBitmap ( ) : Bitmap	Convert bitmap

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Dispose this object This boolean disposing parameter here ensures that objects with a finalizer is not disposed, this is method is invoked from the finalizer. Do overwrite, and call, this method in base classes if you use any unmanaged resources.

Method Details

Convert() public method

Image format conversion. refer to the documentation for supported image formats

The converted image size may be rounded (up) due to format constraints. See Image.FourCC for how to get the fourCC code.

public Convert ( uint format ) : Image
format	uint	/// FourCC format to convert to. ///
return	Image

Dispose() public method

Release resources held by this object

public Dispose ( ) : void
return	void

Dispose() protected method

Dispose this object

This boolean disposing parameter here ensures that objects with a finalizer is not disposed, this is method is invoked from the finalizer. Do overwrite, and call, this method in base classes if you use any unmanaged resources.

protected Dispose ( bool disposing ) : void
disposing	bool	/// A False if called from the finalizer, True if called from Dispose. ///
return	void

FourCC() public static method

Get FourCC code from four chars

See FourCC.org for more information on FourCC. For information on format supported by zbar see: http://sourceforge.net/apps/mediawiki/zbar/index.php?title=Supported_image_formats

public static FourCC ( char c0, char c1, char c2, char c3 ) : uint
c0	char
c1	char
c2	char
c3	char
return	uint

Image() public method

Create/allocate a new uninitialized image

Be aware that this image is NOT initialized, allocated. And you must set width, height, format, data etc...

public Image ( ) : System
return	System

Image() public method

Create image from an instance of System.Drawing.Image

The converted image is in RGB3 format, so it should be converted using Image.Convert() before it is scanned, as ZBar only reads images in GREY/Y800

public Image ( System image ) : System
image	System	/// Image to convert to ZBar.Image ///
return	System

ToBitmap() public method

Convert bitmap

public ToBitmap ( ) : Bitmap
return	System.Drawing.Bitmap
