A single point: point = { "type": "point", "properties": {...}, "geometry": [x, y] } Multiple lines with common properties: lines = { "type": "lines", "properties": {...}, "geometry": [ (x0, y0, x1, y1), # 1. line (x0, y0, x1, y1), # 2. line .... ] } Lines can contain points where x0 == x1 and y0 == y1! A single linear path without filling: path = { "type": "path", "properties": {...}, "geometry": [path-command, ...] } SVG-like path structure: - The first path-command is always an absolute move to "M" - The "M" command does not appear inside a path, each path is a continuouse geometry (no multi-paths). path-command = ("M", x, y) = absolute move to ("L", x, y) = absolute line to ("Q", x0, y0, x1, y1) = absolute quadratice Bezier curve to - (x0, y0) = control point - (x1, y1) = end point ("C", x0, y0, x1, y1, x2, y2) = absolute cubic Bezier curve to - (x0, y0) = control point 1 - (x1, y1) = control point 2 - (x2, y2) = end point ("Z",) = close path Multiple filled paths: Exterior paths and holes are mixed and NOT oriented by default (clockwise or counter-clockwise) - PyQt and SVG have no problem with that structure but matplotlib requires oriented paths. When oriented paths are required the CustomJSONBackend can orient the paths on demand. filled-paths = { "type": "filled-paths", "properties": {...}, "geometry": [ [path-command, ...], # 1. path [path-command, ...], # 2. path ... ] } A single filled polygon: A polygon is explicitly closed, so first vertex == last vertex is guaranteed. filled-polygon = { "type": "filled-polygon", "properties": {...}, "geometry": [ (x0, y0), (x1, y1), (x2, y2), ... ] } ceZdZddZej ddZddddZeddZ eddZ eddZ edd Z edd Z edd Zedd Zy ) _JSONBackendcJg|_d|_d|_d|_d|_y)Ng{Gz?皙?g?) _entities max_sagittamin_lineweightlineweight_scalingfixed_lineweightselfs 9lib/python3.12/site-packages/ezdxf/addons/drawing/json.py__init__z_JSONBackend.__init__ps+/1""%!$cyNr(s r* get_json_dataz_JSONBackend.get_json_datazs$'r,indentcLtj|j|S)z$Returns the result as a JSON string.r2)jsondumpsr0)r)r3s r* get_stringz_JSONBackend.get_string|szz$,,.v>>r,c|jr#|jdzdz }td||_|j|_|jdk(r|j|_|j|_y)Ngffffff9@i,r!r")r%maxr&r'max_flattening_distancer$)r)configmin_lineweight_mms r* configurez_JSONBackend.configuresi  & 5 5 OW WWBBD'D5FD DD$V V.?V VVr,c t|dk(rgS|j}t|j|jfg}|j D]}|j }|jtjk(r-|jt|j|jfZ|jtjk(r-|jt|j|jf|jtjk(rP|j}|jt|j|j|j|jf|jtj k(s0|j"}|j$}|jt&|j|j|j|j|j|jf|r|jt(|S)Nr)rr| MOVE_TO_ABSrurvcommandsr}rdrMOVE_TOrfLINE_TO LINE_TO_ABS CURVE3_TOctrl QUAD_TO_ABS CURVE4_TOctrl1ctrl2 CUBIC_TO_ABS CLOSE_PATH)rrr}rcmdc1c2s r*rrsP 4yA~  C"CEE35512H}}gg 88w & OO[#%%7 8 XX ( OO[#%%7 8 XX** *B OO["$$ceeSUUC D XX** *BB OO\244rttRTT355#%%P Q  # Or,r PropertiesMaker TransformFuncRingGeoJsonPolygonc"|t|d|dS)aReturns the property dict:: { "color": color, "stroke-width": stroke_width, "layer": layer, } Returning an empty dict prevents properties in the GeoJSON output and also avoids wraping entities into "Feature" objects. r1rk)ro)rFrqrls r*properties_makerr>slA. r,c2|j|jfS)zsDummy transformation function.

GeoJSON uses a geographic coordinate reference system, World Geodetic System 1984 `EPSG:4326 `_, and units of decimal degrees. - Latitude: -90 to +90 (South/North) - Longitude: -180 to +180 (East/West) So most DXF files will produce invalid coordinates and it is the job of the **package-user** to provide a function to transfrom the input coordinates to EPSG:4326! The :class:`~ezdxf.addons.drawing.recorder.Recorder` and :class:`~ezdxf.addons.drawing.recorder.Player` classes can help to detect the extents of the DXF content. Default implementation: .. autofunction:: no_transform Factory function to make a transform function from WGS84 World Mercator `EPSG:3395 `_ coordinates to WGS84 (GPS) `EPSG:4326 `_. .. autofunction:: make_world_mercator_to_gps_function The GeoJSON format supports only straight lines so curved shapes are flattened to polylines and polygons. The properties are handled as a foreign member feature and is therefore not defined in the GeoJSON specs. It is possible to provide a custom function to create these property objects.
