Detailed Description

Reading and writing of DXF files.

This class can read in a DXF file and calls methods from the interface DL_EntityContainer to add the entities to the contianer provided by the user of the library.

It can also be used to write DXF files to a certain extent.

When saving entities, special values for colors and linetypes can be used:

Special colors are 0 (=BYBLOCK) and 256 (=BYLAYER). Special linetypes are "BYLAYER" and "BYBLOCK".

Member Function Documentation

void DL_Dxf::addAttrib (  DL_CreationInterface *  creationInterface  )

fp Input
Handle of input file.
Return values:
true if line could be read
false if fp is already at end of file
Todo:
Change function to use safer FreeBSD strl* functions

Is it a problem if line is blank (i.e.

, newline only)? Then, when function returns, (s==NULL).

DL_DimensionData DL_Dxf::getDimData (   ) 
 

Returns:
dimension data from current values.

int DL_Dxf::getLibVersion (  const char *  str  ) 
 

Returns:
the library version as int (4 bytes, each byte one version number). e.g. if str = "2.0.2.0" getLibVersion returns 0x02000200

Return values:
true If file could be opened.
false If file could not be opened.

bool DL_Dxf::in (  const string &  file,
DL_CreationInterface *  creationInterface
) 
 

Reads the given file and calls the appropriate functions in the given creation interface for every entity found in the file.

Parameters:
file Input Path and name of file to read
creationInterface Pointer to the class which takes care of the entities in the file.
Return values:
true If file could be opened.
false If file could not be opened.

DL_WriterA * DL_Dxf::out (  const char *  file,
DL_Codes::version  version = VER_2000
) 
 

Opens the given file for writing and returns a pointer to the dxf writer.

This pointer needs to be passed on to other writing functions.

Pointer to an ascii dxf writer object.

bool DL_Dxf::processDXFGroup (  DL_CreationInterface *  creationInterface,

bool DL_Dxf::readDxfGroups (  FILE *  fp,
DL_CreationInterface *  creationInterface,
int *  errorCounter = NULL
) 
 

Reads a group couplet from a DXF file.

Calls another function to process it.

A group couplet consists of two lines that represent a single piece of data. An integer constant on the first line indicates the type of data. The value is on the next line.

This function reads a couplet, determines the type of data, and passes the value to the the appropriate handler function of creationInterface.

fp is advanced so that the next call to readDXFGroups() reads the next couplet in the file.

Parameters:
fp Handle of input file
creationInterface Handle of class which processes entities in the file
Return values:
true If EOF not reached.
false If EOF reached.
