we encode the thumbnail directly after the header, but we need/want? to encode it with r13c3 much later (at the very end, after MEASUREMENT). and then patchup the address/crc in the header.
currently we do write the wrong header.thumbnail_address, mismatching the actual thumbnail start (fixed)
r13b1-r14: directly after header (88)
r13c3-r2000: after MEASUREMENT or AUXHEADER
as from the spec r13-r2000:
* HEADER
* FILE HEADER
* HEADER VARIABLES
* CLASS
* MEASUREMENT (R13 only, optional)
* PADDING (R13C3 and later)
* THUMBNAIL (Pre-R13C3)
* OBJECTS
* HANDLES
* OBJECT FREE SPACE (optional)
* MEASUREMENT (R14-R2000, optional)
* AuxHEADER (=SECOND HEADER, optional for R13C3 and later)
* THUMBNAIL (R13C3 and later)

I converted a DWG with an empty model space and one paper space layout to JSON using `dwgread`. I then converted that JSON back to DWG using `dwgwrite`. When trying to open the DWG AutoCAD 2024 fatal errors ("unhandled access violation").
When doing the `dwgwrite` I get a fair few errors/warnings (just a sample of the "scariest" looking ones);
```
ERROR: Required object or entity key missing
ERROR: Unknown MTEXTOBJECTCONTEXTDATA.num_unknown_bits 488 ignored
ERROR: Unexpected STRING at 1386408 of 1509528 tokens, expected OBJECTS OBJECT. json_OBJECTS:3042
ERROR: Expected JSON STRING
ERROR: Unknown num_dashes field
ERROR: Unknown EVALUATION_GRAPH.unknown_bits ....
ERROR: Unknown subclass field EVAL_Node.node
Warning: Object handle not found 3305242624/0xC5020000
```
Would it be okay to email over the DWG?
Also I see encoding only supports outputting to the the 2000 format, is writing to a later format still on the roadmap?

Hi,
I successfully convert the dwg file to geojson but all the attributes are missing.
For example
In my dwg file I have something like this
and in my geojson I cannot see this properties.
`{
"type": "Feature",
"id": "3DA",
"properties": {
"SubClasses": "AcDbEntity : AcDbBlockReference",
"Layer": "UnitDetail",
"Color": 256,
"name": "UnitDetail",
"EntityHandle": "3DA"
},
"geometry": {
"type": "Point",
"coordinates": [ 368462.7367884437553585, 2682140.4038846166804433, -0.0044009092129904 ]
}
}`
Is there any way to extract this attributes as key value pairs?

Hello Maintainers,
I have a bug report open on huntr.dev, available [here](https://huntr.dev/bounties/8ccb62e1-d25a-45af-87fd-b9e4f0a5087b/), which has been pending for some time. I am keen to assist in resolving this promptly and am willing to close it if deemed out of scope or invalid. Your guidance on this would be appreciated.
Thanks in advance for your time and consideration.

For some reason I'm singing myself/ the company I work at for up to this. If you dont want it or there is no PR in 6 months - please close this.
C/C++ is "nice", "python" is - ML only - as far as I'm concerned.
The JSON "intermittent" step is a pain (see #837) so I need easy access to the structs.

This is me getting - "nit picky", just close if you dont agree.
If you try to build a stock build on a fresh Ubuntu system (I.E as per the instructions in the README) you need the "texinfo" package - requiring needless Perl packages in my case (this instance doesn't need docs, its "cattle" not a "pet").
`./configure --help` shows no option to disable this (I can see) - can this be avoided?

Texinfo requires alot of packages. --disable-docs

For me a 1.5MB DWG gets expanded to about 21MB of JSON, which is about a 1300% increase in storage requirements!
Luckily I can trash the JSON when I'm done but the storage requirements is quite the increase.
A wild guess would be the JSON keys being repeated "long_strings" does the most damage.
Is the filesize a concern for this project? I'm guessing probably not

Hey, long time no support request - great work on the library! :wave:
Ive got a DWG i'm trying to read to JSON and get the following errors;
```
$ ../programs/dwgread -O json -o ./dwgread-DR.json dr_test.dwg -v3

ERROR 0x540
```
In this particular case I could ask the designer to tidy up (anonymize) the drawing and submit it, but over the next few days ill be running this on a few hundred thousand DWG's, which I suspect will contain more errors.
At that many drawings we're abit beyond "tidy up and submit" for bug fixes, is there any log/information that would be useful from parsing "so many" DWGs at once? Maybe some kind of aggregate statistics about common errors?
The file dates go back years but I suspect the earliest file format is whatever was shipped with ACAD 2011, the latest being whatever is being shipped with ACAD now.

e.g. tablet_from_autocad_r10_mac.json.err
this error comes from illegal layer color.index defaults, because the decode already fails before in ptr tbl VPORT.size overflow.

new version defaults, don't write r2000, but old versions asis
dwg readers would prefer r2000 or higher, oda can only read from r9 on,
but for the sake of sanity and less up/downconversions don't upconvert preR13 to r2000 per default.
only <r1.4 upconvert to r1.4, and >=r2004 down to r2000.
This way we have much less up/downconverting changes.
see branch work/write-prer13asis

Actual situation:
Example (Blank AC2.10 DWG file)
[BLANK.DWG.gz](https://github.com/LibreDWG/libredwg/files/12431679/BLANK.DWG.gz)
After conversion to JSON, there is BLOCK_HEADER in the form:
```
...
{
}
...
```
Because code (in src/out_json.c):
```
...
case DWG_TYPE_BLOCK_HEADER:
if (dat->version <= R_12
&& strEQc (obj->tio.object->tio.BLOCK_HEADER->name, "*MODEL_SPACE"))
{
LOG_TRACE ("Skip *MODEL_SPACE\n");
return 0;
}
...
```
Which generates an ERROR log in conversion from JSON to DWG:
```
ERROR: Required (null).type missing, skipped
```
Because JSON ```{}```.
I think that is bad.
Some possibilities:
1) Remove {} from JSON, this means no error log.
2) Remove the code above and generate JSON code like:
```
{
"object": "BLOCK_HEADER",
"index": 5,
"type": 49,
"handle": [0, 1, 31],
"size": 0,
"flag": 0,
"name": "*MODEL_SPACE",
"block_offset_r11": 4294967295,
"unknown_r11": 0
},
```
Which seems somehow right.
The result after conversion from JSON to DWG is fine.
@ruban What do you think?

What about BLOCK_HEADER in DWG->JSON conversion in preR13?

I am saving dwg file as geojson file from command line with dwgread.exe. when I look at the geographic coordinates... it shows 6 digits after the comma. 6 digits is not enough for geographic coordinates. How can I make it to have at least 10 digits.

```dwgadd -v9 --as r9 -o test.dwg test.dwgadd```
Output:

I think that is better to print handles in the second header in handle format.
Example 1
```
handles[13].num_hdl: 1 [RCd 0]
handles[13].nr: 13 [RCd 0]
hdl: { 0xd } [*RC]
```
to something like
```
handles[13].nr: 13 [RCd 0]
handles[13].handle: (?.1.D) abs:13 [H 0]
```
Example 2
```
handles[10].num_hdl: 2 [RCd 0]
handles[10].nr: 10 [RCd 0]
hdl: { 0x2 0x2a } [*RC]
```
to something like
```
handles[10].nr: 10 [RCd 0]
handles[10].handle: (?.2.22A) abs:554 [H 0]
```

Test scenario:
Input DWG file (blank file from AutoCAD 2000):
[test.dwg.gz](https://github.com/LibreDWG/libredwg/files/12361564/test.dwg.gz)
When I convert to JSON, 10th handle in JSON:
```
{
"nr": 10,
"hdl": [
11
]
},
```
Which is backup of ```VX_CONTROL_OBJECT: (3.1.B) abs:11 [H 0]```
After conversion from this JSON to DWG, result will be:
```
handles[10].num_hdl: 1 [RCd 0]
handles[10].nr: 10 [RCd 0]
hdl: { 0x8 } [*RC]
```
As I see, each time will be 0x8 from JSON conversion to DWG. This is bad.

need to handle possible double-bytes?
either into TU codepage specific, or into utf8 (as injson and indxf)
the IS_FROM_TU macro would be also wrong for the first currently implemented case, at least for BIG5, GB2312
* 932 is single-byte for most chars, but 0x8*, 0x9*, 0xE* and 0xF* lead bytes
* CP949, JOHAB, ANSI_949, 936, 950 for all > 0x8* lead bytes
* 1361 for all but 0x8[0123], 0xD[4567F], 0xF[A-F] lead bytes
* BIG5, GB2312 are two-byte only
...
none have valid 0x00 bytes. so it looks like nothing to fix here.
only logging can be improved to match the current user locale. (UTF-8 or other)

```

< "index": 256,
< "rgb": "c3000007"
---
> "rgb": "c0000000"
```
There is the conversion of fill_color (CMC) defined by (AC1015):
```
rowstyles[rcount1].fill_color.index: 256 [CMC.BS 63]
rowstyles[rcount1].fill_color.rgb: 0xc3000007 [CMC.BL 421]
fill_color.method: 0xc3 Truecolor
rowstyles[rcount1].fill_color.flag: 0x0 [CMC.RC]
```
to JSON, where is:
```
"fill_color": {
"index": 256,
"rgb": "c3000007"
},
```
This means that rgb color doesn't exist in index table → index=256
See:
```
bit_read_CMC()
{
...
color->index = dwg_find_color_index (color->rgb);
...
}
```
and
```
EXPORT BITCODE_BS
dwg_find_color_index (BITCODE_BL rgb)
{
Dwg_RGB_Palette pal;
rgb &= 0x00ffffff;
pal.r = (rgb >> 16) & 0xFF;
pal.g = (rgb >> 8) & 0xFF;
pal.b = rgb & 0xFF;
// linear search is good enough for 256. the palette is unsorted.
for (BITCODE_BS i = 0; i < 256; i++)
{
if (memcmp (&pal, &rgb_palette[i], 3) == 0)
return i;
}
return 256;
}
```
When I am converting this JSON back to DWG, result will be:
```
rowstyles[rcount1].text_color.flag: 0x0 [CMC.RC]

The problem with this is, that was called:
```
if (dat->from_version >= R_2004)
bit_downconvert_CMC (dat, color);
```
in bit_write_CMC().

Hi.
When I input statement “dwgread –O GeoJSON –o outjson Arc.dwg” in cmd, the program keeps waiting and cannot run. What is the reason for this?

Hi,
I see in the bindings folder that only perl and python are supported.
Is there a way to use it for JAVA/Android?
Thank you very much,

We have an issue in dwg_find_color_index(), which is not working.
The problem is with:
```
BITCODE_BL rgb = 0xff0000;
Dwg_RGB_Palette pal;
pal.r = rgb & 0xff0000;
```
where BITCODE_BL is uint32_t and pal.r is unsigned char and conversion isn't working.

In https://github.com/LibreDWG/libredwg/issues/346 I described roundtripping issue in conversion between JSON and DWG.
In the conversion from DWG to JSON is used:
```
DWG_TABLE (LTYPE)
...
FIELD_BINARY (strings_area, 256, 0);
```
in dwg.spec
The result of the conversion of "" is 512 character string with zeros.
In the conversion from JSON to DWG is used:
```
in_hex2bin() ...
```
in in_dxf.c
The result of the conversion of 512 character string with zeros is "0".
I am curious when we have in_hex2bin without tests, and there is a copy of this function in unit-testing/add_test.c.
I think that could be fine to have one function and tests with it. + Fix of this issue.

In order to display the type and name of each handle, starting with HEADER, we'd need to prescan all objects (HANDLES) at least for the type, for table records even up to its name.
Currently we can display it only for back references, not future objects.
e.g.
```
reactors[0]: (4.1.C) abs:12 [H* 330] => DICTIONARY
ownerhandle: (12.1.E) abs:381 [H 330] => BLOCK_HEADER bloko
layer: (5.1.8A) abs:138 [H 8] => LAYER Tavolo 3
```
Benefit:
Many ODA errors stem from invalid references. This way we could easier see where they are pointing to.
Cost:
Abstract decode_section_handles for all 3 versions.
Seperate handles and decode_add_object code for 2000, 2004 and 2007. From 1 phase to 3 phases:
* 0 for single-pass (-v3),
* 1 for first pass (allocate objects and skip),
* 2 for second pass (already allocated, full object from spec).
|
prescan objects with -v4

In postR13 is in the header handle for these default LTYPE values.
But in preR13 it quietly does not find a handle for these types.
```
...
if (vars->LTYPE_BYLAYER)
return vars->LTYPE_BYLAYER;
...
```
in https://github.com/LibreDWG/libredwg/blob/master/src/dwg.c#L2580-L2581
In the case of CONTINUOUS, there is the process of creating this LTYPE before this setting. Then there is the possibility to set vars->LTYPE_CONTINUOUS after creating.
|
Question: What about default LTYPE values like BYLAYER, BYBLOCK, CONTINUOUS in preR13?

I am going to improve flags_r11 setting.
I created PR https://github.com/LibreDWG/libredwg/pull/757 which:
* Describe these numbers precisely
* Added flags_r11 from the structure if is defined
One thing is TODO, which I am not able to set now:
* Add ```dwg->header.section[id].flags_r11 = __FROM_CONTROL__``` in https://github.com/LibreDWG/libredwg/blob/master/src/in_json.c#L3264 It helps conversions from JSON to DWG and better ability to test conversion from DWG to JSON and back.

Could not link test program to Python. Maybe the main Python library has been

The actual situation with parsing of POLYLINE and VERTEX entities in preR13 is this:
* In preR13 is one entity for all POLYLINE and VERTEX types. This means, that the DWG file contains a flag for the (un)presence of variables in the entity and an optional flag (default without this flag is POLYLINE_2D, VERTEX_2D) which means which entity type is present (3D, MESH, PFACE)
* We have naive parsing (polyline - https://github.com/LibreDWG/libredwg/blob/master/src/decode.c#L6614, vertex - https://github.com/LibreDWG/libredwg/blob/master/src/decode.c#L6630) based on entity variables which is not valid for detection.
* There are issues like the entity is presented as POLYLINE_3D, but it's POLYLINE_MESH. Same with VERTEX.
I created [PR](https://github.com/LibreDWG/libredwg/pull/711) for a fix of the polyline, but the issue is with the naivety of parsing.
What about this?
Possibilities:
* Add better detection in the actual block - this means adding parsing of entity flag, which is after elevation, handle, and other common entity things, and will create detection based on this flag.
* Add code for common parsing of preR13 POLYLINE and VERTEX entities - different that POLYLINE_3D (and others) in dwg.spec. And we do some convert to concrete entities.
Example of failing POLYLINE MESH:
[PFACE.DXF.gz](https://github.com/LibreDWG/libredwg/files/11341290/PFACE.DXF.gz)
[PFACE.DWG.gz](https://github.com/LibreDWG/libredwg/files/11341291/PFACE.DWG.gz)
There are other failing situations.
