Tips: How to Invoke One Inkscape Extension from Another + Other stuff I learned when writing the extension
by Shlomi Fish
Hi all,
here are some tips you can use from my experience on working on an inkscape
extension:
1. Calling one extension from another:
--------------------------------------
This is the recipe I used in Python to call one extension from another:
import subprocess
def id_arg(my_id):
return '--id=' + my_id
with_perspective_applied_text = subprocess.check_output(
['python',
'/usr/share/inkscape/extensions/perspective.py',
id_arg(main_path_id()),
id_arg(pers_e.get_path_id()),
pers_e.calc_out_fn()
]
)
main_path_id() and pers_e.get_path_id() are the IDs passed to the extension as
selections and pers_e.calc_out_fn() contains the path to where the
intermediate SVG was written.
This can be done securely by doing:
temp_dir = tempfile.mkdtemp()
def temp_svg_fn(basename):
global temp_dir
return join(temp_dir, basename + '.svg')
2. Output from inkex.Effect to a file.
------------------------------------------
The following class that inherits from inkex.Effect writes to a temporary file
instead of to STDOUT.
[QUOTE]
class GenericAddPathEffect(inkex.Effect):
def __init__(self, basename):
self.basename = basename
inkex.Effect.__init__(self)
def effect(self):
draw_generic_style_path(self.get_path_name(), self.get_path_id(),
self.current_layer, self.calc_d_s()
)
def calc_out_fn(self):
return temp_svg_fn(self.basename)
def write_to_temp(self, input_fn):
self.affect(args=[input_fn], output=False)
with open(self.calc_out_fn(), 'w') as fh:
self.document.write(fh)
return
[/QUOTE]
Customise it to your heart's content. (Note that the passing of parameters is a
little counter-intuitive now - I'm planning to fix it).
3. Adding a gradient:
---------------------
You can add a gradient by manipulating the <defs section in the file. See:
[QUOTE]
class StyleEffect(GenericAddPathEffect):
def effect(self):
self.xpathSingle(u'svg:defs').insert(0,
inkex.etree.XML('''<svg:linearGradient
xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg"
id="bk2hp_grad"> <stop style="stop-color:#0000ff;stop-opacity:1" offset="0"
id="b2h_0" />
<stop style="stop-color:#00deff;stop-opacity:1"
offset="0.4"
id="b2h_1" />
<stop style="stop-color:#00deff;stop-opacity:1"
offset="0.6"
id="b2h_2" />
<stop style="stop-color:#0000ff;stop-opacity:1"
offset="1"
id="b2h_3" />
</svg:linearGradient>''')
)
self.xpathSingle(u'svg:defs').insert(1,
inkex.etree.XML('''<svg:linearGradient
xmlns:svg="http://www.w3.org/2000/svg" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" id="bk2hp_grad_rot"
gradientTransform="rotate(90)" xlink:href="#bk2hp_grad" />''') )
self.xpathSingle(u'//*[@id="' + main_path_id() + '"]').set( 'style',
simplestyle.formatStyle({ 'stroke': '#888888', 'stroke-width': '1pt',
'fill': 'url(#bk2hp_grad_rot)',
}
))

svg for web pages.
by john Culleton
I am planning to convert one of my web sites to all-svg. I am wondering
about the use of a site map. Is it the same as for an html site (with
different names of course)?
