c35310445a rename text_convert to text_transform to match css naming convention (also matching enums to css) 2010-09-18 19:10:18 +00:00

035e99d2f0 Only initialize proj_transform once in metawriter_json_stream. 2010-08-02 12:14:27 +00:00

d5b0432dd7 Many metawriter improvements: 
- Easier to configure
- Correct JSON output
- Handling more than one renderer run (writing pre-/postamble is no longer done in constructor/destructor)
- Collect all attributes required by metawriters

9a0bcf23be Added basic infrastructure for metawriter and support for JSON output (limited to PointSymbolizer atm) 2010-07-06 00:37:05 +00:00

89f6b32b76 apply patch from Herm from #553 adding support for markers_symbolizer to Cairo renderer, new placement finder, and fill/spacing/overlap options - works nicely with new svg support being tested against markers_symbolizer 2010-05-30 03:16:51 +00:00

1e2ffb22b7 cairo rendering for the glyph_symbolizer. Small refactoring in cairo_context::add_text to pass the paramaters which were picked up from the text_symbolizer param (size, fill, halo_radius and halo_fill) explicitly. This allows the glyph_symbolizer to piggy back on that functionality without specilizing add_text() for the glyph_symbolizer (which would have involved heavy amounts of copy+paste or a more elaborate refactoring strategy. Please ping me if this was not a good idea 2010-03-19 09:33:57 +00:00

fc3a1beeef initial skeleton of glyph_symbolizer (coarsely ported from arrow_symbolizer). Mapnik compiles but symbolizer does nothing useful yet and is going to be heavily modified to make use of expressions to be general enough to be usable for purposes other than rendering arrows representing vector direction/intensity 2010-03-18 20:04:35 +00:00

b8511eca65 restore default behavior of PointSymbolizer when used without an image, by defaulting to 4x4 black pixel - TODO - expose colors, shapes, and size for this in the future 2010-03-03 03:26:12 +00:00

85ecc33d7f + applied patch from Jochen Topf : 
* text_convert="none|toupper|tolower"
 Convert all text to upper/lower case before rendering. "none" doesn't do
 anything with the text and is the default. Works for labels along lines
 or at points.

* line_spacing="<number>"
 Add this many pixels space between two lines in text labels that have
 been broken into several lines. Default is 0. Doesn't do anything for
 labels along lines.

* character_spacing="<number>"
 Add this many pixels space between two characters in a text. Default is 0.
 Currently only works for text labels on point geometries. This should
 also be implemented for labels along lines, but I'll leave that for
 another day.

* wrap_character="<character>"
 Instead of breaking text into lines on spaces, use this character. This
 is useful, when you want to make sure that labels are broken at the right
 spot. Note that you'll probably want to make wrap_width small so that
 your lines are actually broken, otherwise you'll see the wrap_character
 in the output. Default is ' ' (space). Doesn't do anything for labels
 along lines.

2eec236fc2 + applied "hill shading" patch from Marcin Rudowski 
a) Raster opacity
   b) Raster merging modes (TODO:add more modes, consider agg impl)
   c) Raster scaling algos: fast,bilinear,bilinear8
      (TODO: add alpha support in bilinear8) 
   d) improvements to png256

   *Great work, thanks!*

d11654895b Utilise color alpha information when rendering. Multiplies the color alpha with the rendering opacity. Fixes 221. 2009-02-07 14:09:23 +00:00

220bb3e99a Revert the patch to add a show_page flag to the cairo renderer and 
replace it with support for rendering to a cairo context rather than
a cairo surface.

When rendering to a surface a show_page is done, when rendering to a
context it is not so that multiple renders can be done, possibly with
modified scaling and/or translation.

9408a41a5c Add opacity support to the point symbolizer - taken from r743 which 
added the same support to the agg renderer.

that null is neither equal nor not equal to other things.
