News

Version 0.7.3 - 2014-05-16

• NEW: options = {"assure_3d_coords": True}, guarantees (x, y, z) tuples for ALL coordinates, this option is by default False

• NEW: extended TrueColor() class, see docs

• NEW: dxfgrabber.aci_to_true_color(index) returns the DXF default true color value for AutoCAD Color Index index as TrueColor()

• NEW: added is_backwards, is_upside_down, width, oblique, font, bigfont attributes to TEXT, ATTRIB, ATTDEF entities

• NEW: added plain_text() method to TEXT, ATTRIB and ATTDEF to get text content without formatting codes like ‘%%u’

• NEW: added font, bigfont, rect_width, horizontal_width and vertical_height attributes to MTEXT

• NEW: added resolve_text_styles(text_styles) method to TEXT, ATTRIB, ATTDEF, MTEXT entities

• NEW: new import option “resolve_text_styles” and it is True by default

• NEW: added extrusion direction to all entities

• NEW: added row_count, col_count, row_spacing, col_spacing attributes to INSERT.

• NEW: MText.plain_text(split=False) tries to remove format codes, returns a single string or a list of strings

• NEW: added n_smooth_density, m_smooth_density, smooth_type to Polymesh

• NEW: added smooth_type to Polyface

• CHANGE: LWPolyline again: LWPolyline.points list of (x, y) or (x, y, z) depends on “assure_3d_coords”, LWPolyline.width list of (start-width, end-width), .bulge list of floats, removed LWPolyline.get_rstrip_points() and added .const_width attribute (if != 0, ignore .width list).

• CHANGE: Polyline method points() is now a field (list) and added lists for width and bulge for consistent APIs of LWPolyline and Polyline.

• BUGFIX: wrong DXF subclass for Arc.extrusion (error in DXF Standard)

Version 0.7.2 - 2014-05-09

• NEW: grabs SAB data of BODY, 3DSOLID, … entities for DXF version AC1027 (R2013) and later

• NEW: support for dxf attributes: true_color (AC1018), transparency (AC1018), shadow_mode (AC1021) in prior DXF versions this attributes are set to None.

• NEW: using Cython for some speed optimizations, but Cython is not a installation requirement; control the Cython extension by environment variable DXFGRABBER_CYTHON = ON|OFF, by default the Cython extension is activated.

• CHANGED: LWPolyline.points are always 5-tuples (x, y, start_width, end_width, bulge)
