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.

018852148c Don't try and include cairo support in the python bindings if we
haven't built mapnik itself with cairo support.

4586586448 added convinence overloads for 'save_to_file' and 'render_to_file'
Example:
	>>> from mapnik import *
	>>> im = Image(200,200)
	>> save_to_file('test.png',im) # Guess image type from file extension
	>> save_to_file('test.png,'jpeg',im) # Explicitly save as JPEG

b2df387a9d - merged strict-xml-branch r530:532 to trunk:
- libxml2 support
    - strict error handling while parsing XML map files
    - implemented save_map()
    - removed some duplicate defaults
    - all symbolizers with icons share a common base class now

9fe4a94c98 Added minimum_distance property to text symbolizers. This prevents the same label from appearing within N pixels (across features).
Shield symbolizer is now a subclass of text symbolizer.
Some small improvements to text rendering.
Fixed up placement finder for horizontal placement.
Cleaned up placement finder.

af44541598 implemented query_map_point method on map object:

TODO: provide interface to feature in Python, at the moment only __str__ implemented which dumps attributes

913b273f40 applied missing part from mapnik_tile patch 2006-12-04 20:12:58 +00:00
Artem Pavlenko
4d4e9f5d91 Tiling patch from Toby allows for a selected pixel region within an extent
to be rendered. This allows for a large extent (larger than can be
rendered into a single image in memory) to be rendered out as tiles.
Since the full extent is used for the placement calculations text
crossing tile boundaries will be consistent.

This method is a little inefficient when a large number of labels need
placed, an improved method would be to cache these placements between
tiles, but the attached is a start.

c++ users should simple call the render method with a start X and Y
coordinate specified, 

for (int TileX = 0;TileX < 5;++TileX)
{
	for(int TileY = 0;TileY < 5; ++TileY)
	{
		int TileSize=250;
		int StartX = TileX*TileSize;
		int StartY = TileY*TileSize;
		
		Image32 buf(TileSize,TileSize);
		agg_renderer<Image32> ren(m,buf,StartX,StartY);
		
		ren.apply();
		char name[324];
		sprintf(name,"tile_%d_%d.png",TileX,TileY);
		ImageUtils::save_to_file(name,"png",buf);
	}
}

python users should call render_tile_to_file

for y in range(tile_count_y):
	for x in range(tile_count_x):
		if not os.path.exists("tiles/%d/%d/" % (map_scale, y)):
			os.makedirs("tiles/%d/%d/" % (map_scale, y))
		render_tile_to_file(m, x*tile_size, y*tile_size, tile_size, tile_size,
'tiles/%d/%d/%d.png' % (map_scale,y,x), 'png')

f1393cc019 1. hit_test implementation for geometry objects:
bool hit_test(double x, double y, double tol);
       
2. added image_view(unsigned x, unsigned y, unsigned width, unsigned height)
   allowing to select region from image data e.g (in Python):

    im = Image(2048,2048)
    view = im.view(0,0,256,256)
    save_to_file(filename,type, view)
    
3. changed envelope method to return vy value in datasource classes

4. features_at_point impl for shape and postgis plug-ins

f76079f15b 1) Added line following labels. Use set_label_placement(POINT_PLACEMENT) or set_label_placement(LINE_PLACEMENT) on a text symbolizer.
2) Added placement_finder class so labels try to avoid each other.
3) Added Shield Symbolizer which is essentially a combined image/text symbolizer.

bb235fa316 1.added projection transformation support based on proj4 (new dependency!!!)
Map and Layer objects both have a new parameter 'srs', initialized to "+proj=latlong +datum=WGS84" by default. 
    
  Basic usage (Python):
    p = Projection("+proj=merc +datum=WGS84")
    point = p.forward(Coord(-2,51))
    ...        
2.reflected arithmetic operators for Envelope/Coord into Python
3.altered return policies for python objects
4.modified build system to require proj4 lib and headers
