libredwg-0.12 released

Item posted by Reini Urban <reini_urban> on Thu 31 Dec 2020 05:16:59 PM UTC.

New add API to easily create new DWGs (or DXFs) from scratch, for CAD programs.
New dwgadd helper.
Removed deprecated old API functions.

New features:
  * Add a new experimental dwg_add_ENTITY/OBJECT API for easier CAD write support,
    starting with GauchoCAD and SolveSpace. Most entities and some objects.
    Similar to the VBA interface and object model, just with our names.
  * cmake support enhanced to programs and LTO. Should be usable now by its own,
    but MSVC is untested.
  * Add a new experimental dwgadd helper, to create fresh DWG's easily from scratch.
  * Added support for many more object/entity types:
    Now stable: ACSH_CONE_CLASS ACSH_TORUS_CLASS BLOCKALIGNMENTPARAMETER
      BLOCKALIGNMENTGRIP BLOCKLOOKUPGRIP BLOCKROTATIONGRIP
    Now unstable:
      ALDIMOBJECTCONTEXTDATA ASSOC2DCONSTRAINTGROUP ASSOCACTIONPARAM
      ASSOCARRAYACTIONBODY ASSOCARRAYMODIFYPARAMETERS
      ASSOCARRAYPATHPARAMETERS ASSOCARRAYPOLARPARAMETERS
      ASSOCARRAYRECTANGULARPARAMETERS ASSOCASMBODYACTIONPARAM
      ASSOCCOMPOUNDACTIONPARAM ASSOCDIMDEPENDENCYBODY ASSOCFACEACTIONPARAM
      ASSOCOBJECTACTIONPARAM ASSOCOSNAPPOINTREFACTIONPARAM
      ASSOCPATHACTIONPARAM ASSOCPOINTREFACTIONPARAM ASSOCVARIABLE
      ASSOCVERTEXACTIONPARAM BLKREFOBJECTCONTEXTDATA
      BLOCKALIGNEDCONSTRAINTPARAMETER BLOCKANGULARCONSTRAINTPARAMETER
      BLOCKARRAYACTION BLOCKDIAMETRICCONSTRAINTPARAMETER
      BLOCKHORIZONTALCONSTRAINTPARAMETER BLOCKLINEARCONSTRAINTPARAMETER
      BLOCKLOOKUPACTION BLOCKLOOKUPPARAMETER BLOCKPARAMDEPENDENCYBODY
      BLOCKPOINTPARAMETER BLOCKPOLARGRIP BLOCKPOLARPARAMETER
      BLOCKPOLARSTRETCHACTION BLOCKRADIALCONSTRAINTPARAMETER
      BLOCKREPRESENTATION BLOCKSTRETCHACTION BLOCKUSERPARAMETER
      BLOCKVERTICALCONSTRAINTPARAMETER BLOCKXYGRIP DATALINK EVALUATION_GRAPH
      FCFOBJECTCONTEXTDATA GRADIENT_BACKGROUND GROUND_PLANE_BACKGROUND
      IBL_BACKGROUND IMAGE_BACKGROUND LEADEROBJECTCONTEXTDATA
      MTEXTOBJECTCONTEXTDATA PARTIAL_VIEWING_FILTER PARTIAL_VIEWING_INDEX
      PLANESURFACE POINTCLOUD POINTCLOUDCOLORMAP POINTCLOUDDEF
      POINTCLOUDDEFEX POINTCLOUDDEF_REACTOR POINTCLOUDDEF_REACTOR_EX
      POINTCLOUDEX RENDERENTRY RENDERENVIRONMENT RENDERGLOBAL
      SKYLIGHT_BACKGROUND SOLID_BACKGROUND TEXTOBJECTCONTEXTDATA
    Debugging changes: Renamed ATEXT to ARCALIGNEDTEXT,
      Added POLARGRIPENTITY.
  * Added dwg_obj_generic_handlevalue(), dwg_obj_generic_dwg(),
API breaking changes:
  * Disable old deprecated functional API, all object-specific field getters
    and setters. Re-enable with -DUSE_DEPRECATED_API
  * Renamed UNDERLAY to {PDF,DGN,DWF}UNDERLAY and likewise PDFDEFINITION, ...
  * Disable static for Windows. This shrinks the released Windows zip file
    from 41MB to 24MB. The 0.10.1 had 20MB, 0.6.1 15MB.
Minor features:
  * fix more C++ compatiblity: restrict is __restrict, disable __nonnull.
    Now successfully used in SolveSpace.
  * Add gperf hash tables for all objects and dxfclasses, for faster lookup
    dxfnames to create classes, and object names with most properties.
    Previously lookup was linear, now constant. Needs also less memory.
  Simplified API: dwg_obj_generic_parent(), dwg_ent_generic_parent() to take void.
  * Added public geometry helpers: dwg_geom_angle_normalize(), dwg_geom_normalize(),
    dwg_geom_cross(), dwg_geom_transform_OCS()
Major bugfixes:
  * Enable python shared lib, add -no-undefined and PYTHON_LIBS.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libredwg-0.12.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys B4F63339E65D6414

and rerun the 'gpg --verify' command.
