-- Concept : translate SVG file in GEO .obj file and try to load it.
-- Curiousity : the original matrix must be :
0.0 0.0 1.0 0.0
0.0 1.0 0.0 0.0
0.0 0.0 1.0 0.0
0.0 0.0 0.0 1.0
and not:
1.0 0.0 0.0 0.0
0.0 1.0 0.0 0.0
0.0 0.0 1.0 0.0
0.0 0.0 0.0 1.0
-- Options :
SHARP_IMPORT = 0
choise between "As is", "Devide by height" and "Devide by width"
SHARP_IMPORT = 1
no choise
-- Possible bug : sometime, the new curves object's RotY value
jumps to -90.0 degrees without any reason.
Yet done:
M : absolute move to
Z : close path
L : absolute line to
C : absolute curve to
S : absolute curve to with only one handle
H : absolute horizontal line to
V : absolute vertical line to
l : relative line to 2004/08/03
c : relative curve to 2004/08/03
s : relative curve to with only one handle
h : relative horizontal line to
v : relative vertical line to
A : curve_to_a,
V : draw_line_v,
H : draw_line_h,
Z : close_z,
Q : curve_to_q,
T : curve_to_t,

transfrom for <g> tag
transform for <path> tag
Changelog:
0.1.1 : - control file without extension
0.2.0 : - improved reading of several data of the same type
following the same command (for gimp import)
0.2.1 : - better choice for viewboxing ( takes the viewbox if found,
instead of x,y,width and height
0.2.2 : - read compact path data from Illustrator 10
0.2.3 : - read a few new relative displacements
0.2.4 : - better hash for command followed by a lone data
(h,v) or uncommun number (a)
0.2.5 : - correction for gimp import
0.2.6 : - correction for illustrator 10 SVG
0.2.7 : - correction for inskape 0.40 cvs SVG
0.2.8 : - correction for inskape plain SVG
0.3 : - reading of the transform properties added :
translate
0.3.1 : - compatibility restored with gimp
0.3.2 : - transform properties added (june, 15-16):
scale,
rotate,
matrix,
skew
- added a test on __name__ to load the script
outside from the blender menu
0.3.3 : - matrix transform content control
0.3.4 : - paths data reading rewritten (19/06/05)
0.3.5 : - test on empty curve (22/06/05)
- removed overlayed points
0.3.6 : - rewriting of the bezier point contruction to correct
a problem in the connection between L type point and
C or S type point
0.3.7 : - code correction for bezier knot in Curveto command when
the command close a path
0.3.8 : - code was aded to manage quadratic bezier,
Q,q command and T,t commands, as a normal blender's bezier point
- The last modications does not work with gimp 2.0 svg export .
corrected too .
0.3.9 : - Path's A,a command for ellipse's arc .
0.4.0 : - To speed up the function filter_DATA was removed and text
variables are changed into numeric variables
0.4.1 : - svg, groups and shapes hierarchy added
- now transform properties are computed using a stack with all
parented groups
- removed or replaced useless functions :
- skewY, skewX transforms
- radians in rotate transform
0.4.2 : - Added functon to translate others shapes in path
rect, line, polyline, polygon
0.4.3 : - various corrections
text font (id property exported by Adobe Illustrator are between coma)
function to code s tag has been rewritten
0.4.4 : - various corrections
to oblige the script to understand a line feed just after
a tag . Rarely encountered problem, but it exits in a svg file
format exported by a outliner script for mesh .
0.4.5 : - update for CVS only, at least blender 2.38 and upper
no BezTriple module in older version
added a createCURVES function to avoid to use
the OBJ format export/import .
Perhaps problems with cyclic curves . If a closed curve
does not appear closed in blender, enter edit mode select
all knot with Akey, do a Hkey to set handle type (without
this the knot are recalculated) , and finally use the Ckey
to close the curve .
Should work ... not guaranted .
0.4.6 : - cyclic flag ...
0.4.7 : - Management of the svgz files . the complete python or the
gzip.py file is needed .
Little improvement of the curve drawing using the createCURVES
function
0.4.8 : - short modif for a fantasy font case in the OOo svg format
('viewbox' is written 'viewBox', for instance) .
Note that (at this time, 2006/05/01, 1OOo exports in svg
but does not read its own export
0.4.9 : - skipped version : private test
0.5.0 : - the script worked perfectly with Blender 2.41 but in Blender
2.42, use the original svg name file + 'OOO.obj' to
write a videoscape file made blender crash under window XP when
the script loaded it . Curiously, use a more simple
name with a sole 'O' solved this problem .
- script returned errors on open path : corrected
- in b2.42, several successive imports seem to be added to
the same original curve . So now the script automaticaly
renames the last group of imported curve with the original
name file .
0.5.1 : - without join option in the internal curve creation function
0.5.2 : - the createCURVES() function has been cleanded . Now it works
fine but all bezier curves are joined in the same curve object .
0.5.3 : - removed two things :
1/ the ajustement function to increase speed . 35 % faster :
5690 curves and 30254 points in 11 seconds . User should do
a ctrl-a on the object .
2/ the import method menu . No reason to choose between the
old extern curve creat and the new intern curve creation
this last one is largely faster .
0.5.4 : - translation of the functions' name + improvment in the dict lookup .
Quite 15% faster . 9.75 seconds instead of 11 to load the file test .
A test was also added to find the fill style so now the script closes
these curves even if they are not defined as closed in the strict path
commands .
The old non used functions have been completely removed .
0.5.5 : - Modifs for architect users .
