Export labels as SVG text instead of glyphs

[brendensoares]

Is it possible to export labels as SVG text objects instead of linked glyph paths?

I'd like to be able to edit the SVG labels after exporting from tilemill.

Thanks :]

This is a feature that would need to be added to Mapnik to be possible in TileMill. I'm aware that @isti757 has recently added this support to Mapnik. @isti757 is your patch available anywhere?

[isti757]

@springmeyer I would gladly share the patch, but this issue https://github.com/mapnik/mapnik/issues/2244#issuecomment-43396346 doesn't allow

[springmeyer]

@isti757 thanks for your thoughts. TileMill currently uses Mapnik 2.3.x not master, so the patch would be more appropriate (and likely easier for now) against 2.3.x. But definitely still want to solve mapnik/mapnik#2244.

@springmeyer how can i add my patch to 2.3.x?

@isti757 like this:

git clone https://github.com/mapnik/mapnik.git
cd mapnik
git checkout 2.3.x
# make changes to mapnik source code
# then make sure tests pass
make test
# then create a diff
git diff > mypatch.diff

Send me the mypatch.diff

seems that 2.3.x also uses mapnik::keys get_key(std::string const& name); to get the symbolizer properties. I cloned mapnik as you suggested and the following methods are non-existent:

text_symbolizer const& sym

sym.get_text_ratio() sym.get_face_name() sym.get_fontset()->get_name() sym.get_character_spacing() sym.get_text_transform() sym.get_text_size() sym.get_halo_fill()

sorry, missed the line git checkout 2.3.x. Added above.

[isti757]

seems there are some files missing in 2.3.x that are necessary for the patch:

https://github.com/mapnik/mapnik/blob/2.3.x/include/mapnik/text/harfbuzz_shaper.hpp https://github.com/mapnik/mapnik/blob/2.3.x/include/mapnik/text/glyph_info.hpp https://github.com/mapnik/mapnik/blob/2.3.x/include/mapnik/text/icu_shaper.hpp

we were working against the master branch that was checked out Dec 21 2013
