Release 0.12.1

Major bugfixes:

  • fixed dwg_bmp() and dwgbmp for >= r2004. Wrong dat offset.
  • Fixed EED with code 3 for layer handles. (Fixes GH #310, shanzhugit)
  • Fixed bit_convert_TU utf8 conversion with ubsan, wrong endian-ness.
    Various fuzzing errors detected and fuzzed by Chew Kin Zhong (See GH #304):
  • Fix possible null-deref with broken DWG's in dwg_get_first_object.
  • Fix possible null-deref with broken DWG's in dwg_find_class with empty
    CLASS.dxfname. (GH #309)
  • Fix possible null-deref with broken DWG's in dwglayers with empty
    LAYER.name. (GH #308)
  • Fix short integer overflow in EED checks when decoding malcrafted DWG's,
    which also led to encode buffer overflows. (GH #307)
  • Fix possible null-derefs with broken DWG's in json export. (GH #306)
  • Fix possible null-deref with broken DWG's in dwg_next_entity iterator. (GH #305)
  • Fix wrong TFF overflow check for static strings, where we cannot set
    the string nor the size. (GH #304)
  • Fix heap-overflows and invalid free's when decoding broken 3DSOLID's
    in malcrafted DWG's. Only accept version 1 and 2. (GH #304)

Minor features:

  • Added string converters with known TU sizes: bit_TU_to_utf8_len, bit_read_TU_len.

Release 0.11.1

out_dxf bugfixes mostly. 0.11 failed to produce dxf files which could
be imported into AutoCAD. This bugfix release improves DXF importing
from 10% to about 90%. But beware: Some dwg2dxf DXF files still can
silently crash AutoCAD, so be sure to save your DWG's before DXFIN.
Most 3DSOLID's still cannot be imported via DXF, but some can now.
See https://www.gnu.org/software/libredwg/ and NEWS

Major bugfixes:

  • Fixed decode of Unicode string streams (GH #279)
  • Fixed UCS-2 to UTF-8 conversion for the chars 128-255.
  • Fixed DXF output of many objects: VISUALSTYLE, HATCH, DIMENSION*, ATTDEF,
    ATTRIB, TEXT, VIEWPORT, INSERT, SEQEND, VERTEX, BLOCK, STYLE, MULTILEADER,
    DICTIONARY, XRECORD INT64 type, MLINESTYLE angles, SPATIAL_FILTER.origin,
    SPATIAL_INDEX class appname, duplicate STYLE eed, ACDBPLACEHOLDER for r13-r14,
    LAYER.name with |, LAYER.plotflag for Defpoints, LTYPE.shape_flag, STLYE.flag,
    PDFUNDERLAY group 170,
    ACSH_CHAMFER_CLASS, ACSH_FILLET_CLASS, ACSH_BOOLEAN_CLASS, BLOCKBASEPOINTPARAMETER,
    PROXY_OBJECT, PROXY_ENTITY.
    HEADER.DIMSAV.
    Common: lineweight, shadow_flags (GH #275)
  • Moved PSPACE entities from BLOCKS to ENTITIES (GH #277)
  • Fixed \r\n quoting in DXF texts (GH #275)
  • Generalize and fix DXF text splitup into 255 chunks and quoting, add basic
    shift-jis quoting support for Katagana and Hiragana letters
    (Japanese \M+1xxxx => Unicode \U+XXXX)
  • Added indxf dwg_has_subclass check to avoid buffer overflows when writing to
    wrong subclasses. (GH #295)
  • Fixed dwg_dim_blockname calculation, esp. for anonymous blocks.
  • Improved SAB 2 to SAT 1 conversion: Split overlarge blocks into block_size of max 4096.
    Add "^ " quoting rule.
  • Fixed decode of empty classes section, esp. for r13c3 and r14.
  • Keep IDBUFFER for old DXFs (r13-r14)
  • Fixed SummaryInfo types from T to TU16, relevant for DXF headers also (GH #275)
  • Add missing UTF-8 conversion in geojson for TEXT, MTEXT, GEOPOSITIONMARKER. (GH #271)
  • Fixed and improved some Dockerfile, added a check-docker target.
  • Drop unneeded perl/LibreDWG.xs, we rather use the generated c directly.
    Minor features:
  • Add CMake basic library support, so the library can be included into cmake projects.
    (no programs)
  • Improved header C++ compat.
  • Promoted ACSH_HISTORY_CLASS to stable. Needed for ACIS entities in DXF.
  • Added to examples: filt_sat.pl and dec_sat.pl to compare and decode DXF sat parts.
