tilecache-1.9, Wed, 5 Sep 2007 11:14:16 -0400

• Fix longstanding bug which made some non-geographic projections difficult to create tiles with
• Add more informative error message output via TileCacheExceptions
• Fix for “MetaLayer.getMetaSize is too conservative”
• Report OSErrors more cleanly in tilecache_clean.py
• Better support for Jython in DiskCache class.
• Add support for extent_type=loose to allow out of bounds tile requests
• Improved tilecache_seed to only grab one metaTile from each set – this drastically reduces the number of requests to precache metatiled layers. Also fixed off-by-one error where seed was requesting too many tiles.
• Add tms_type=google to specify that the TMS layer should go down instead of up.
• Add setting of labelcache_map_edge_buffer to the MapServer layer if one does not exist on the map object.
• Make mapnik layer respect layers= config if provided.

tilecache-1.8, Fri, 4 May 2007 07:31:38 -0400

• Patch to ImageLayer from Volker Mische add: * Optional transparency to images which are not transparent. This allows

  the images to be transparent outside the maxExtent of the image.

  • Resize scaling method specification

• Add support for tile watermarking, patch by Andrew Hughes.

• Allow for definition of ‘styles’ parameter in WMSLayer tilecache cfg – don’t send blank parameters to the backend.

tilecache-1.7, Fri, 13 Apr 2007 20:34:42 -0400

• Apache will sometimes kill TileCache, leaving around locks. If we can’t lock for > cache.timeout seconds, throw an exception with the lockname, so that users can cleanup. Reported by Brock Anderson, who had stuck locks for several days.
• If ImageLayer base image is transparent, make output Image transparent too. Report and patch by Brian Victor.
• Add support for forcing client to reload on errors, by Suki Hirata.
• Add support for not caching data which is not images for WMS, with original support written by Suki Hirata.
• Minor fixups to TMS metadata, from Suki Hirata.

• Add support for MapnikLayer for rendering.
• Add support for rendering using metatiles: instead of rendering one tile at a time, render a 5x5 tileset, and then slice the tiles up. Good for vector layers, where labels crossing tile boundaries is useful. To turn on, use ‘metaTile=yes’ in layer definition. Requires Python-Imaging.
