GetMIFInfo()

Collects summary information on the contents of an MIF file.

MIF_info = GetMIFInfo(string MIF_file_name, string detail_flag)

Argument	Contents
MIF_file_name	The path and file name of the MIF file
detail_flag	If "True"GetMIFInfo()collects information on the entity types in the file; if "False" this information is not collected

An array of information as follows:

Element	Type	Contents
1	Array	The projection name, option settings, and bounding rectangle of the file, to be passed to ImportMIF(). The projection name may be None (in which case the data are in longitude-latitude coordinates) or Local (indicating that an arbitrary coordinate system was used).
2	Array	An array of four real numbers indicating the coordinate transformation used in the file: {x_multipler, y_multipler, x_offset, y_offset}; to be passed to ImportMIF()
3	String	The MIF file version number
4	Array	An array containing one 4-element array for each data field in the .MID file that is associated with the .MIF file, with a structure as shown below
5	Array	An array of entity type-count pairs indicating the quantity of each type of entity in the file; or null if detail_flag was "False"

Data Field Element	Type	Contents
1	String	The name of the field
2	String	The field type: "String", "Long", "Short", or "Real"
3	String	"True" if the field is indexed in the MapInfo file; "False" if not
4	Boolean	If "True" all values for the field are unique

The entity type-count list includes one entry for each of the following types: NONE, POINT, TEXT, LINE, POLYLINE, SMOOTHED POLYLINE, ELLIPSE, ARC, REGION, RECTANGLE, ROUNDED RECTANGLE.
Files that use a local coordinate system have the units used in the file as the sole projection option.

// This call...

MIF_info = GetMIFInfo("c:\\county.MIF", "True")

// Returns this type of information...

// MIF_info = {

// projection_info, (array of info)

// transform_info, (array of info)

// "2", (version number)

// {{"Name", "String", "True", "True"}, ...}, (attributes and types)

// {{"POINT", 231}, {"TEXT", 100}, ...} (counts by entity type)

// }

Error Type	Meaning
Error	The file is not a valid MIF file
NotFound	There is no MIF file with the given path and file name
