Island detection for the HATCH entity is now supported, the example shows the
effect of the HATCH styles NESTED, OUTERMOST and IGNORE (from left to
right), the example script can be found
here:
The HATCH entity also got support for hatch pattern, but this is just an approximation, because neither matplotlib nor PyQt5 have proper fill pattern support in the style of a CAD application.
Disabling the hatch pattern support is often the better solution:
Set the backend param
hatch_pattern to 0 to disable pattern usage, or set it to 2 to use a
solid fill as replacement for the pattern, or set param show_hatch to 0 to
disable hatch rendering at all.
Support for linetype rendering. The native linetype support by matplotlib and
PyQt5 is fast but not implemented in the way as CAD applications do it. In CAD
applications the linetypes are rendered in real drawing units, this means the
length of lines and gaps is always the same independent of the zoom level.
This is not the case for the matplotlib and the PyQt5 backends, therefore
the drawing add-on provides a custom line renderer, but it's slower than the
native one. The backend param
linetype_renderer controls which line renderer is used, set the param to
"internal" to use the native line rendering of the backend (default), or set
it to "ezdxf" to use the custom line render provided by the add-on.
Font support for TrueType Fonts. SHX fonts have to be substituted by the according TrueType fonts, but the replacement fonts for the SHX fonts are not available for free. The best rendering results can be archived by installing an Autodesk product (TrueView), because this will install the replacement fonts automatically:
The current supported SHX fonts, and their replacement TrueType fonts are listed here.
POINT mode support, see the
docs about the POINT
entity and the various point modes. The DXF format supports only one point mode
for ALL points in a DXF document, because the point mode is defined by the
global header variable $PDMODE. Relative sizing to the viewport is not supported.
Example for POINT mode 66:
MLINE support, but without line break and fill break features (gaps).
Proxy graphic support. If no native rendering support for an entity exist, the proxy graphic will be shown if present (e.g. MLEADER).
The ezdxf.addons.geo module adds support for the __geo_interface__.
See the docs and the
tutorial for more
information.
