Typedef Documentation

typedef struct dxf_block_struct DxfBlock

DXF definition of an AutoCAD block entity.

The Blocks section of the DXF file contains all the Block Definitions.
This section contains the entities that make up the Blocks used in the drawing, including anonymous Blocks generated by the HATCH command and by associative dimensioning.
The format of the entities in this section is identical to those in the Entities section described later, so see that section for details.
All entities in the Blocks section appear between Block and Endblk entities.
Block and Endblk entities appear only in the Blocks section.
Block definitions are never nested (that is, no Block or Endblk entity ever appears within another Block-Endblk pair), although a Block definition can contain an INSERT entity.

External References are written in the DXF file as any Block Definition, except they also include a text string (group code 1) of the path and filename of the External Reference.

Here is the call graph for this function:

DxfBlock* dxf_block_read	(	DxfFile *	fp,
		DxfBlock *	block
	)

Read data from a DXF file into a DxfBlock (a DXF BLOCK entity).

The last line read from file contained the string "BLOCK".
Now follows some data for the BLOCK, to be terminated with a " 0" string announcing the following entity, or the end of the ENTITY section marker ENDSEC.
While parsing the DXF file store data in dxf_block.

Returns:: a pointer to block.

Todo:: After reading information from the BLOCK entity up until the closing Group code 0, the pointer to the following ENDBLK entity needs to be stored in the current (last) DxfBlock struct member endblk.

Todo:: Resolve this quick hack for preventing an empty block name string in a more elegant manner.

Parameters:

fp	DXF file handle of input file (or device).
block	DXF block entity.

Todo:: for version R14.
Implementing the start of application-defined group "{application_name", with Group code 102.
For example: "{ACAD_REACTORS" indicates the start of the AutoCAD persistent reactors group.

application-defined codes: Group codes and values within the 102 groups are application defined (optional).

End of group, "}" (optional), with Group code 102.

Parameters:

fp	DXF file pointer to an output file (or device).
block	DXF block entity
