1 Overview
**********

LibreDWG is a free C library to read and write “DWG files” and “DXF
files”.  The DWG file format is proprietary and was created in the 1970s
for one then-emerging CAD application.

   This library is part of the GNU project, released under the aegis of
GNU. It is made available under GPLv3+, i.e., under the terms of the GNU
General Public License version 3, or (at your option) any later version.

   It came out of code from the QCad Community Edition product from
Ribbonsoft.

1.1 API/ABI version
===================

LibreDWG 0.14 provides the API/ABI version 0.  We hope that this doesn't
need to change much in the future.

   See ‘include/dwg.h’ for ‘LIBREDWG_VERSION_MAJOR’,
‘LIBREDWG_VERSION_MINOR’ and ‘LIBREDWG_SO_VERSION’.

1.2 Coverage
============

Because the DWG file format is not open, its specification had to be
reverse-engineered.  The specification is almost complete.  The LibreDWG
implementation of the specification is an ongoing process; as of version
0.14, coverage is approximately 99%.

   It can read and mostly write all DWG formats from r1.2 to r2018 for
99%.  The internally supported DWG revisions are identified as r1.1,
r1.2, r1.3, r1.4, r2.0b, r2.0, r2.10, r2.21, r2.22, r2.4, r2.5, r2.6,
r9, r9c1, r10, r11b1, r11b2, r11, r13b1, r13b2, r13, r13c3, r14, r2000b,
r2000, r2000i, r2002, r2004a, r2004b, r2004c, r2004, r2007a, r2007b,
r2007, r2010b, r2010, r2013b, r2013, r2018b and r2018.

   Here is a list of features that are still missing:

Writing r2007 DWG
     Writing to the specific r2007 format is not implemented.  We write
     as default in the r2004 or older formats only.

Reading and writing pre-R13 DXF
     Reading and writing pre-R13 DXF's is work in progress.  There is no
     support planned for the very old pre-R2.0 DXF format.

Enabled entities and objects, but unstable, undertested. Field names may change:

1.3 Related projects
====================

Some projects that use DWG (and specifically LibreDWG) are:

FreeCAD
     <https://freecadweb.org/>

GRASS GIS
     <http://grass.osgeo.org/>

   Plans are to add support for SolveSpace, LibreCAD, FreeCAD, OpenSCAD
and PythonCAD.

   Related libraries:

libdwg
     The old version (documented in Esperanto) which was forked to
     LibreDWG in 2009.  But in the meantime it got a DXF reader.
libdxfrw
     Read the DWG format for all versions r13+ but with much less
     elements, only those needed for DXF. Written in C++, under the
     GPLv2 license.
libopencad
     Read the r2000 DWG format.  Written in C++, under the GPLv2
     license.
ACadSharp
     Read and write the basic objects in most DWG and DXF formats.
     Written in C#, under the MIT license.
OpenDWG
     The OpenDWG's license does not allow the usage in free software
     projects.

   Compared to libdwg, libdxfrw and libopencad, LibreDWG can read and
write much more DWG versions and details.  Which is especially important
for attached links and data from third party applications: BIM, MAP,
GIS, AEC, MECH, ..., for 3D solids and dynamic parametric constraints.
The commercial Teigha library is much better though.

2 Usage
*******

This chapter describes how to compile and link a program against
LibreDWG. To access LibreDWG interface elements (*note Types::, *note
Functions::), include its header file in the C code.

     #include <dwg.h>

   Optionally you can also use the
     #include <dwg_api.h>
   API.

Make sure you specify ‘-lredwg’ when linking, such as in this
‘Makefile.am’ fragment:

     AM_LDFLAGS += -lredwg

Note that the shared object library is named ‘libredwg’ (with some
system-specific extension, e.g., ‘.so’), so you do *not* want to specify
‘-llibredwg’, as that would (try to) link against ‘liblibredwg’ and
fail.

3 Types
*******

LibreDWG types map closely to the type system of the DWG file format.
This chapter describes the enums and structs used to define the single
DWG structure, which is passed around the functions (*note Functions::).

 -- define: BITCODE_RC char
     1 raw unsigned char, uint8_t
 -- define: BITCODE_RS short
     1 raw unsigned short int, uint16_t
 -- define: BITCODE_RL long
     1 raw unsigned long int, uint32_t
 -- define: BITCODE_RD double
     1 raw IEEE-754 double
 -- define: BITCODE_B byte
     1 bit
 -- define: BITCODE_BB byte
     2 bits
 -- define: BITCODE_3B byte
     1-3 bits
 -- define: BITCODE_4BITS byte
     4 bits (for VIEW view_mode)
 -- define: BITCODE_BS short
     1 bit-encoded unsigned short
 -- define: BITCODE_BL long
     1 bit-encoded unsigned long (max 32bit)
 -- define: BITCODE_BLL uint64_t
     1 bit-encoded unsigned 64bit long
 -- define: BITCODE_BD double
     1 bit-encoded double
 -- define: BITCODE_DD double
     1 bit-encoded double with default
 -- define: BITCODE_MC long int
     1-4 modular chars
 -- define: BITCODE_UMC long unsigned int
     1-4 unsigned modular chars
 -- define: BITCODE_MS long unsigned int
     1 modular short, max 2 words
 -- define: BITCODE_BE double[3]
     1 bitencoded extrusion vector.

     Note that this specifies an OCS (Object Coordinate System) for each
     entity, with the default (0, 0, 1).  An extrusion of (0, 0, -1) is
     typically caused by exploding a block inserted with a negative x
     scale, i.e.  the sign of each X point needs to be flipped.  For
     more see the vendor DXF documentation on OCS and ‘programs/geom.c’.

 -- define: BITCODE_BT double
     1 bitencoded thickness value
 -- define: BITCODE_TV char*
     length + ASCIIZ string The default text type until r2004.
 -- define: BITCODE_TU wchar*
     length + windows 2-byte wchar string (UCS-2).  The default text
     type since r2007.
 -- define: BITCODE_TF char*
     Fixed length buffer, which can include NUL characters.
 -- define: BITCODE_TFF char*
     Embedded fixed length string, which can include NUL characters.
 -- define: BITCODE_H void*
     handle-references
 -- define: BITCODE_CMC struct Dwg_Color
     Dwg_Color struct with index or rgb, alpha and optional DBCOLOR
     handle, name, book_name.
   [and some more]

   Two types that do not derive from the type system of the DWG file
format are the enums for return codes and error codes.

   On non-C99 systems ensure that stdint.h and inttypes.h are available
to use the proper C99 ‘int32_t’,...  types, and not just the native
fallback types int/long, which are different across platforms.

   The r2004 format (used for r2004 and r2010-r2018) and r2007 format
knows the following sections:

   The old pre-R13 formats (from r1.1 to r11) have those sections, with
the tables interleaved into the HEADER.

   With r11 came the additional tables:

   But we convert them internally to r2004 table record and table
control objects.  *Note Tables::.

5.2 OBJECTS Section
===================

The OBJECTS Section is usually split up into multiple pages (separate
sections of type AcDbObjects) and contains all entities and objects.  It
is indexed by *note HANDLES::.

   *Note OBJECTS: Objects.


File: LibreDWG.info,  Node: CLASSES,  Next: HANDLES,  Prev: OBJECTS_,  Up: Sections

5.3 CLASSES Section
===================

The *Classes* Section contains the basic info for all dynamically loaded
types for entities and objects.  Its types start with 500, and are
variable.  An entity which has no class loaded is displayed as proxy.

   LibreDWG contains support for many classes, but not all.  See
‘src/classes.inc’ and ‘src/classes.c’.  We define a stability for each
class, one of stable, unstable, debugging and unhandled.

   Objects in *stable* classes are treated as the fixed-type objects
with full support.  Changes are treated as API breaking.

   Objects in *unstable* classes are sometimes written to DXF or JSON,
but not always to DWG. Changes are not treated as API breaking.  Usually
such objects are converted to UNKNOWN_OBJ or UNKNOWN_ENT objects, and
when written to DWG converted to PLACEHOLDER, DUMMY or POINT objects
with EED pointing to the original class and content.  Only when
rewriting from-to the very same version with the full known unknown_bits
blob (e.g.  dwgrewrite or json) such classes can persist as such.

   Objects in *debugging* classes are only handled with the developer
‘configure --enable-debug’ flag, otherwise ignored.  See unstable above.

   Objects in *unhandled* classes are always ignored.  There are no
fields known, only its type.

File: LibreDWG.info,  Node: Tables,  Next: EXTRAS,  Prev: SYSTEM_MAP,  Up: Sections

5.22 Tables
===========

The old pre-R13 formats (from r1.1 to r11) have no objects and no
sections, just tables, which we store in the sections indexed by the
enum Dwg_Section_Type_r11.

   BLOCKS LAYER STYLE LTYPE VIEW

   With r11 came the additional tables:

   UCS VPORT APPID DIMSTYLE VX

   Since r13 all those tables are stored as table control objects and
tablerecord objects.

   From pre-r13 DWG's these tables are imported as old r11 sections and
as new CONTROL objects, so that all entities are accessible via the
single BLOCK_CONTROL.model_space -> BLOCK_HEADER.entities iterator, all
layers via the LAYER_CONTROL.entries -> LAYER objects, and so on.  All
blocks are accessed via all other model_space BLOCK_HEADER's,
‘get_first_owned_block (BLOCK_HEADER)’.  Each CONTROL object holds a
list of all table records, i.e.  entries.  Each table record entry has a
name and other common table fields.

   The VX table (also vport_entity table) is a special table until r2004
for VIEWPORT entities, which are VPORT extensions, esp.  for Paper
Space, but have no old-style table records.  So VX_CONTROL contains a
list of matching VX_TABLE_RECORD's, which are pointed to by
VIEWPORT.vport_entity_header handles.  Likewise the VX_TABLE_RECORD
object links in its viewport field back to the VIEWPORT. The VX table is
not represented in DXF, on DXF import we need to create them with the
VIEWPORT entities.


File: LibreDWG.info,  Node: EXTRAS,  Prev: Tables,  Up: Sections

5.23 EXTRAS entities section
============================

Before R13 we had no objects, just the 5-10 tables, and the entities
divided into 3 sections.  The entities, the blocks and the extras.
Blocks just contains the entities from each BLOCK to the ENDBLK entity.

   Extras contain entities which had no room in the original section,
e.g.  when closing a polyline, which needs one additional byte.  Thus
the original entity is replaced by an undocumented JUMP entity, which
gives the offset into the EXTRAS section, until a JUMP in the EXTRAS
jumps back to the next original entity.

   See e.g.  ‘r10/entities.dwg’

   The JUMP [31] replaces the POLYLINE_2D entity which got later closed.
An open POLYLINE_2D needs size 8, but closed 9 bytes.  Hence they added
the new closed replacement to the extras section at offset 0, index
[66], and added another JUMP [67] back to the next original entity.
Here it jumps back to the VERTEX_2D [32] at offset 0x84f.

6 Structures
************

* Menu:

* EED::            eed[] array
* XDATA::          xdata list for XRECORD


File: LibreDWG.info,  Node: EED,  Next: XDATA,  Up: Structures

6.1 EED
=======

"Extended Entity Data" (EED) may be optionally attached to each object.
They consist of a handle to the registered APPID, and a list of typed
data.  Each block is preceded with a size, the processing stops with
size 0.

   Internally libredwg stores each eed line as an array of num_eed
structs.  If the size > 0, then new block starts with a handle, an
optional raw string (when reading from a DWG), and a number of typed
data entries.  Only the first eed struct of each block has a size, all
subsequent eed structs have size 0.

   Example:
       EED[0] size: 109 [BS]
       EED[0] handle: 5.2.762
       EED[0] code: 70 [RC] short: 2 [RS]
       EED[1] code: 70 [RC] short: 0 [RS]
       EED[2] code: 70 [RC] short: 0 [RS]
       EED[3] code: 11 [RC] 3dpoint: (0.000000, 0.000000, 0.000000) [3RD]
       EED[4] code: 11 [RC] 3dpoint: (1.000000, 0.000000, 0.000000) [3RD]
       EED[5] code: 11 [RC] 3dpoint: (0.000000, 1.000000, 0.000000) [3RD]
       EED[6] code: 11 [RC] 3dpoint: (0.000000, 0.000000, 1.000000) [3RD]
       EED[7] size: 6 [BS]
       EED[7] handle: 5.2.763
       EED[7] code: 70 [RC] short: 0 [RS]
       EED[8] code: 70 [RC] short: 0 [RS]
       EED[9] size: 23 [BS]
       EED[9] handle: 5.1.12
       EED[9] code: 0 [RC] string: "RTMaterial" len=10 cp=30
       EED[10] code: 5 [RC] entity: 0x6507000000000000 [RLL]
       - size: 0 [BS]

   These 10 num_eed structs consist of 3 blocks with 3 size and handle
entries.  EED[0] starts with size 109, the handle pointing to object
762, 3 shorts and 4 points.  The next block at EED[7] has size 6, the
handle pointing to object 763 and 2 shorts.  The last block at EED[9]
has size 9, the handle pointing to object 12 (the APPID.ACAD
application) and a string and an entity reference.  The size is
calculated by the needed room for all data code + values, without the
handle.  E.g.  EED[7] size: 6 is 1 + 2 for EED[7] RC + RS, and 1 + 2 for
EED[8] RC + RS.

   Each data block consists of a RC code, and a variable value.  A
string may be a an old pre-r2007 ASCII string with a RC length (max 255
chars), a codepage and the string.  Or a r2007+ wide string with a RS
length (max 32767 chars) and a UCS-2 wide string.

   decode stores both, the raw data, and the structured data.  in_dxf
just the data.  encode prefers raw over the data.


File: LibreDWG.info,  Node: XDATA,  Prev: EED,  Up: Structures

6.2 XDATA
=========

XRECORD XDATA are very similar to the EED array, but internally it is a
single linked-list, consisting of something like the EED data code +
value pairs.  There's only one size, xdata_size, and only one handle to
the APPID, which handles this XRECORD XDATA.

7 Functions
***********

You can use LibreDWG immediately upon loading, without any particular
initialization.  Only when using some *note dynapi:: functions you might
need to initialize the version via ‘dwg_api_init_version(&dwg)’, when
you need other formats than r2000 and you call an API function which
does not store the version internally.  Most do.  This limitation will
soon be fixed.

   You usually use one set of functions - either decoding or encoding -
at a time.  All functions use the common data types (*note Types::).
All functions return an error code, and the high-level functions for
multiple objects add the error bitmask, which is sorted by severity.
When the error exceeds DWG_ERR_CRITICAL, processing is stopped.

   The new *note dynapi:: has dynamic get and set functions for all
objects and its fields.  You can get and set a property value from any
object pointer by the object name and the field name.

* Menu:

* Decoding::                    Functions on the DWG read path.
* Encoding::                    Functions on the DWG write path.
* add api::                     How to create a DWG and objects from scratch
* dynapi::                      Dynamic object field access.
* strings::                     The various string types, how Unicode strings are handled
* Other Formats::		Functions on the DWG to read or write other formats.


File: LibreDWG.info,  Node: Decoding,  Next: Encoding,  Up: Functions

7.1 Decoding
============

The highest level function for decoding a file is *‘dwg_read_file’*.

 -- Function: int dwg_read_file (char *FILENAME, Dwg_Data *DWG)
     Open FILENAME and decode it, saving information into DWG.  Return 0
     if successful.

   You can then iterate over the entities in model space or paper space
via two ways:

   1.  by using the ‘dwg.h’ data structures.  Via ‘dwg->object[0]’,
which is of type ‘Dwg_Object_BLOCK_CONTROL’, and a custom ‘void
process_BLOCK_HEADER(Dwg_Object_Ref* ref)’:

  Dwg_Object_BLOCK_CONTROL* block_control = dwg->block_control;
  // first all entities in the model space
  process_BLOCK_HEADER (dwg->header_vars.BLOCK_RECORD_MSPACE);
  // then all entities in the blocks
  for (i=0; i < block_control->num_entries; i++)
    {
      process_BLOCK_HEADER (block_control->entries[i]);
    }
  // and last all entities in the paper space
  process_BLOCK_HEADER (dwg->header_vars.BLOCK_RECORD_PSPACE);

   or 2.  by using the API functions from ‘dwg_api.h’:

  Dwg_Object_BLOCK_CONTROL* block_control = dwg_block_control(dwg);
  process_BLOCK_HEADER (dwg_model_space_ref(dwg));
  for (i=0; i < block_control->num_entries; i++)
    {
      process_BLOCK_HEADER (block_control->entries[i]);
    }
  process_BLOCK_HEADER (dwg_paper_space_ref(dwg));

   and inside the ‘process_BLOCK_HEADER’ function, you iterate over the
entities from the block_header via:

  Dwg_Object* obj = get_first_owned_entity(ref->obj);
  while (obj)
    {
      process_object(obj);
      obj = get_next_owned_entity(ref->obj, obj);
    }

   where ‘process_object’ checks the type of each entity under the
DWG_OBJECT* OBJ.

   For each entity or object type (i.e.  a non-graphical dwg object,
also tables) there also exist the simple and expensive
‘dwg_getall_ENTITY’ and ‘dwg_getall_OBJECT’ functions:

 -- Function: int dwg_getall_ENTITY (Dwg_Object_Ref *BLOCK_HEADER_REF)
     Return a malloc'ed NULL-terminated array of all such entities for
     Model Space, Paper Space or an individual block.

 -- Function: int dwg_getall_OBJECT (Dwg_Data *DWG)
     Return a malloc'ed NULL-terminated array of all such DWG objects.

   The decoder is driven by the fields definition in the ‘src/dwg.spec’,
which adds each field to the object.  This is done in the ‘src/decode.c’
or ‘src/decode_r2007.c’.
 -- Function: int dwg_decode_OBJECT (Bit_Chain *DAT, Dwg_Object *OBJ)
     Sets the fields for the object from the DWG bitstream.

   Note: Pre-R13 DWG's do contain all deleted entities, which e.g.
where moved into a BLOCK. Those entities do have a type > 127.  You need
to filter them out by yourself, when processing the DWG.


File: LibreDWG.info,  Node: Encoding,  Next: add api,  Prev: Decoding,  Up: Functions

7.2 Encoding
============

Encoding DWG files, i.e.  DWG write support, can be disabled via
‘./configure --disable-write’.  We support writing all formats but
r2007.  r2010-r2018 formats still fail CRC and audit checks though.  The
pre-r13 formats are much simpler and can be written, but need some
hand-holding and manual conversions when converting from newer formats
still.

   See ‘src/in_dxf.c’ for a high-level usage example.  The default
codepage is Latin-1, 30.

   The highest level function for encoding a bitstream to a file is
‘dwg_write_file’, which dumps the dwg to a file.

 -- Function: int dwg_write_file (char *FILENAME, Dwg_Data *DWG)
     Open FILENAME and write the DWG to it.  Return 0 if successful.

   *Note add api:: for:
 -- Function: Dwg_Data* dwg_add_Document (const Dwg_Version_Type
          VERSION,
     const int IMPERIAL, const int LOGLEVEL) Creates an initial template
     dwg structure in memory, suitable to be written to a DWG or DXF
     file, without any additional table records or entities.  Creates
     ModelSpace, PaperSpace and most Tables and basic Dictionaries.
   and how to add entities and objects from scratch.

   Low level-functions:

 -- Function: int dwg_add_object (Dwg_Data *DWG)
     Adds a new uninitialized object to the DWG->OBJECT[] array.  Return
     0 or -1 if successful, otherwise DWG_ERR_OUTOFMEM. -1 is the array
     was re-allocated.

   Then for each object or entity type there is a
 -- Function: int dwg_setup_<OBJECT> (Dwg_Object *OBJ)
     Initializes an object for the given OBJECT or ENTITY type, with all
     fields being zero'ed.  This does not initialize the OBJ size, type,
     address, handlestream_size, bitsize fields.

   The encoder is driven by the fields definition in the ‘src/dwg.spec’
and the generated ‘src/dynapi.c’, which adds each field to the object.
This is done by ‘src/encode.c’ or any ‘src/in_*.c’ import module.

 -- Function: int dwg_encode_<OBJECT> (Bit_Chain *DAT, Dwg_Object *OBJ)
     Encodes the DWG bitstream from the fields of the object.

   The iterator is similar to above, but you want to encode all data
structures, not just the entities.  But note that you need many helper
functions, such as the *note dynapi::, to create all needed sections to
store a DWG if you didn't read a DWG into the right a DWG_DATA* DWG
struct already.  This is especially important when importing from DXF or
from an earlier or later DWG version.


File: LibreDWG.info,  Node: add api,  Next: dynapi,  Prev: Encoding,  Up: Functions

7.3 add api
===========

The add api functions are useful for CAD programs which want to write
DWG. All the other API's are mostly to convert from and to DWG, so the
main structures and links already do exist.  With the add api you can
easily create an empty DWG from scratch, add table entries (into fixed
Tables or variables Dictionaries), and add entities.  To set more entity
fields use the *note dynapi::.

   For each almost each entity and table exists a function at to add it,
with arguments to initialize some fields as in the VBA object model.
The other objects are either created automatically, or handled
separately.

   All BITCODE_T strings are encoded as UTF-8, as with the dynapi.
*Note strings::.  Most names are copied, since most names are considered
to be constant.  If not, you need to free them by yourself.  Exceptions
are dxfname (there exists a separate dxfname_u variant), the VX name,
which does not exists anymore since r2000.

   A very simple example using the add API is the example program *Note
dwgadd::.

 -- Function: Dwg_Data dwg_add_Document (const Dwg_Version_Type VERSION,
          const int IMPERIAL, const int LOGLEVEL))

     Creates an initial template dwg structure in memory, suitable to be
     written to a DWG or DXF file, without any additional table records
     or entities.  Creates ModelSpace, PaperSpace and most Tables and
     basic Dictionaries.

     When writing DWG, a VERSION of R_2000 is recommended, R_2007 is not
     yet supported.  When writing R_2010 - R_2018 we still do fail CRC
     and audit checks in Teigha and other CAD applications.  For DXF you
     can try all versions R_13 - R_2018.

   For each OBJECT and ENTITY type there exists a specific
‘dwg_add_<OBJECT>’ function, which takes the owner and some default
arguments.  Entities are normally added to a block header, like
modelspace, paperspace or any block.  Objects are normally added to the
dwg, or to some other object or entity.  E.g.
 -- Function: Dwg_Entity_LINE *line = dwg_add_LINE
          (Dwg_Object_BLOCK_HEADER *modelspace,
     dwg_point_3d *start_pt, dwg_point_3d *end_pt)
 -- Function: Dwg_Entity_TEXT* dwg_add_TEXT (Dwg_Object_BLOCK_HEADER
          *restrict BLKHDR, const char* restrict TEXT_VALUE, const
          dwg_point_3d *restrict INS_PT, const double height)

     Adds a TEXT entity to the ModelSpace, PaperSpace or a Block.
     Entity specific arguments are here the text, the point (as pointer
     to the struct of 3 doubles), and the text height.
 -- Function: Dwg_Object_LAYER *layer = dwg_add_LAYER (Dwg_Data *dwg,
          const char *name)
     Adds a new layer the Layer Table, i.e.  creates the new LAYER
     object, and adds it to LAYER_CONTROL object, the list of layers.

   Names and strings are encoded as UTF-8 and will be translated to type
BITCODE_T (i.e.  versions specific TU or TV types, either UCS-2 unicode
or single-byte codepage) internally, as with the dynapi.  Only
internally you will have to deal with 2 different DWG text
representations: UCS-2 since r2007, single-byte before.  *note
strings::.

   To understand the object model for the add API see some VBA Object
model documentation, such as e.g.  <http://entercad.ru/acadauto.en/>.

   The new add API mostly handles the direct ‘Dwg_Entity_ENTITY’
structs, not all the generic ‘Dwg_Object’ structs.  Thus you can access
the object specific fields directly, the common fields, not so easily.

   The DWG Document consists of 3 basic entity containers ‘ModelSpace’,
‘PaperSpace’ and ‘Blocks’, plus ‘Tables’ (‘Layers’, ‘Linetypes’, ...),
‘Dictionaries’ as generic replacements of ‘Tables’ with a root
Dictionary, the ‘NOD’ ("Named Object Dictionary"), and more support
objects and complex entity groups.

   Helper functions:

 -- Function: dwg_add_u8_input (Dwg_Data *restrict DWG, const char
          *restrict U8STR)
     Convert UTF-8 strings to BITCODE_T fields.  Returns a copy of the
     string.  All external API's only deal with UTF-8 strings.

7.4 dynapi
==========

The new dynapi replaced the old dwg_api functions to access each object
field.  The old dwg_api functions were deprecated, and need to be
re-enabled by defining ‘CFLAGS="-DUSE_DEPRECATED_API"’.  See *note
Objects:: for an description of each object and its fields..

   For each of header, entity, common or subclass there is a function to
get and set the value of any type, or converted utf8 string.

 -- Function: bool dwg_dynapi_entity_value (void *ENTITY, const char
          *DXFNAME, const char *FIELDNAME, void *OUT, Dwg_DYNAPI_field
          *FP)
     ENTITY is of type ‘dwg_ent_generic’, that is the pointer to the
     object specific struct.  DXFNAME is the dxfname of the object,
     FIELDNAME is the field or property name of the field to be read
     from, *OUT the result pointer and the optional *FP is filled by the
     information for this field.

 -- Function: bool dwg_dynapi_common_value (void *ENTITY, const char
          *FIELDNAME, void *OUT, Dwg_DYNAPI_field *FP)
     This accesses the common ‘Dwg_Object_Object*’ or
     ‘Dwg_Object_Entity*’ fields.

 -- Function: bool dwg_dynapi_header_value (void *DWG, const char
          *FIELDNAME, void *OUT, Dwg_DYNAPI_field *FP)
     This accesses the Header (or sometimes also called Database)
     fields.

 -- Function: bool dwg_dynapi_subclass_value (void *PTR, const char
          *SUBCLASS, const char *FIELDNAME, void *OUT, Dwg_DYNAPI_field
          *FP)
     This accesses a subclass, a structure within the object.

   The utf8text functions convert version-specific text strings to UTF-8
strings.  Internally the dwg stores strings as TU (unicode) or TV
(single-byte codepage).  The API treats all strings as UTF-8, as with
JSON, DXF or the add API.

 -- Function: bool dwg_dynapi_entity_utf8text (void *ENTITY, const char
          *DXFNAME, const char *FIELDNAME, char *TEXTP, int *ISNEWP,
          Dwg_DYNAPI_field *FP)
     isnewp is set to 1 f the string is a fresh copy, for unicode
     strings.

 -- Function: bool dwg_dynapi_common_utf8text (void *ENTITY, const char
          *FIELDNAME, char *TEXTP, int *ISNEWP, Dwg_DYNAPI_field *FP)

 -- Function: bool dwg_dynapi_header_utf8text (void *DWG, const char
          *FIELDNAME, char *TEXTP, int *ISNEWP, Dwg_DYNAPI_field *FP)
     This accesses the Header (or sometimes also called Database)
     fields.

 -- Function: bool dwg_dynapi_subclass_utf8text (void *PTR, const char
          *SUBCLASS, const char *FIELDNAME, char *TEXTP, int *ISNEWP,
          Dwg_DYNAPI_field *FP)
     This accesses a subclass, a structure within the object.

   The setters don't differentiate between common values and strings.

 -- Function: bool dwg_dynapi_entity_set_value (dwg_ent_generic *_OBJ,
          const char *FIELDNAME, const void *VALUE, const bool IS_UTF8)
     Sets the ENTITY.fieldname to a value.  A malloc'ed struct is passed
     by ptr, not by the content.  A non-malloc'ed struct is set by
     content.  Arrays or strings must be malloced before.  We just set
     the new pointer, the old value will be freed.  If is_utf8 is set,
     the given value is a UTF-8 string, and will be converted to TV or
     TU

 -- Function: bool dwg_dynapi_header_set_value (Dwg_Data *DWG, const
          char *FIELDNAME, const void *VALUE, const bool IS_UTF8)

 -- Function: bool dwg_dynapi_common_set_value (dwg_ent_generic *_OBJ,
          const char *FIELDNAME, const void *VALUE, const bool IS_UTF8)

API's.
