## Future
|
||||
|
||||
- Added to python bindings: `has_tiff`, `has_png`, `has_webp`, `has_proj4`, `has_svg_renderer`, and `has_grid_renderer`
|
||||
|
||||
- Made it possible to disable compilation of `grid_renderer` with `./configure GRID_RENDERER=False` (#1962)
|
||||
|
||||
- Added `webp` image encoding and decoding support (#1955)
|
||||
|
||||
- Added `premultiplied` property on mapnik::image_32 / mapnik.Image to enable knowledge of premultiplied status of image buffer.
