Revision: 1.32

• Intel compatible PC with Windows NT 4.0 (Service Pack 3).
• Successfully installed MATROX driver Meteor.sys.
• Matrox DLLs mil.dll, milhost.dll, milmet.dll, miltiff.dll, milvga.dll, and milvhook.dll.
  These DLLs must be within your search path %PATH% (typically, they reside in the directory C:\Winnt\system32). If you do not have these DLLs, please contact Matrox or the vendor from which you bought the framegrabber board. Note that this interface was created based on the Matrox DLLs version 4.0.
• HALCON framegrabber interface Meteor.dll (revision 1.30 or higher).
  Older revisions may be not compatible with HALCON 5.2. If you have properly installed the interface, Meteor.dll should reside in bin\i486-nt4 within the HALCON base directory %HALCONROOT% you have chosen during the installation of HALCON.

• One framegrabber board with one camera.

• No LUTs.

Parameters for open_framegrabber():

	Name	'Meteor'	The name of the HALCON framegrabber interface.
	FGWidth	1, 2, 4, width	The desired image resolution. Use '1' for full resolution, '2' for subsampling by factor 2, '4' for subsampling by factor 4. Default: 1.
	FGHeight	1, 2, 4, height	The desired image resolution. Use '1' for full resolution, '2' for subsampling by factor 2, '4' for subsampling by factor 4. Default: 1.
	Width	0, width	The width of the desired image part ('0' stands for for the complete image). Default: 0.
	Height	0, height	The height of the desired image part ('0' stands for for the complete image). Default: 0.
	StartRow	0, row	The row coordinate of the upper left pixel within the desired image part ('0' obviously results in delivering the complete image). Default: 0.
	StartColumn	0, column	The column coordinate of the upper left pixel within the desired image part ('0' obviously results in delivering the complete image). Default: 0.
	Field	---	Ignored.
	Bits	8, 24	Number of bits per pixel: Grayscale (8 bits) or color (24 bits). Specifies the video input (together with the parameters 'Generic' and 'Port'); please refer to the table below. Default: 24.
	ColorSpace	'rgb'	Desired color space. Default: 'rgb'.
	Gain	---	Ignored.
	ExternalTrigger	'false'	External triggering is not supported. Default: 'false'.
	Generic	'NTSC', 'PAL', see below	The generic parameter is used to specify the video signal: 'NTSC' or 'PAL'. Default: 'PAL'. Furthermore, there exist 13 more values for the parameter 'Generic' corresponding to the MATROX MIL library; please refer to the table below.
	Device	---	Ignored.
	Port	1, 2, 3	Specifies the video input (together with the parameters 'Bits' and 'Generic'): '1' denotes the S-VHS jack, '2' the RCA (composite video) jack, and '3' the RGB (SUBD) jack; please see also the table below. Default: 1.
	LineIn	1	The desired input line (fixed). Default: 1.

Specify the video input by the following Bits/Generic/Port combinations:

Parameters for set_framegrabber_param(): Not supported.

Parameters for get_framegrabber_param():
