GetDXFInfo()

Collects summary information on the contents of a DXF file.

dxf_info = GetDXFInfo(string dxf_file_name, string detail_flag)

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

An array of information as follows:

Element	Type	Contents
1	Array	An array of strings indicating the names of layers in the DXF file, or null if the DXF file header is missing
2	Array	An array of four real numbers indicating the bounding coordinates of the file: {x_min, y_min, x_max, y_max}
3	String	The DXF file version number, or null if the DXF file header is missing
4	Array	An array of strings indicating the names of the applications that created the file, or null if this information is missing
5	Array	An array of field name-type pairs identifying the name and type of attributes in the file; or null if detail_flag was "False"
6	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"

If detail_flag is "True" GetDXFInfo() uses but does not release memory holding the results. You should call either ImportDXF() or ClearDXFInfo() to release this memory.
The entity type-count list includes one entry for each of the following types: POINT, TEXT, LINE, POLYLINE, ARC, POLYGON, CIRCLE, 3DFACE, SOLID, and TRACE.
Valid field types are "Long", "Real", and "String."

// This call...

dxf_info = GetDXFInfo("c:\\drawing.dxf", "True")

// Returns this type of information...

// dxf_info = {

// {"Street", "Water", "Bldgs", ... }, (layer names)

// {2000, 8000, 42600, 31000}, (bounding rect)

// "R11", (version number)

// {"ACAD"}, (application)

// {{"Name", "String"}, {"Level", "Long"}}, (attributes and types)

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

// }

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

Function	Summary
ImportDXF()	Imports features from a DXF file into a geographic file
ClearDXFInfo()	Frees memory used by GetDXFInfo()
