How to get line type, such as Dotted line, Dashed line tiny #235

Closed zhengf312 closed 4 years ago

zhengf312 commented 4 years ago

I found libreDWG can get "BYLAYER"/"BYBLOCK"/"CONTINUOUS" line type from dwg file. But i can't find others line type, such as "Dotted line"/"Dashed line tiny". How to get it?

if (!strcasecmp (pair->value.s, "BYLAYER")) flags = 0; if (!strcasecmp (pair->value.s, "BYBLOCK")) flags = 1; if (!strcasecmp (pair->value.s, "CONTINUOUS")) flags = 2; dwg_dynapi_common_set_value ( _obj, "ltype_flags", &flags, 0);

The ltype property is a handle to the a LTYPE entry. The description you posted is from the DXF reader, which handles it different.

See https://github.com/LibreDWG/libredwg/blob/master/src/common_entity_handle_data.spec

If ENTITY.ltype_flags < 3 then it's one of the 3 special cases, if 3 follow the handle.
