From db31b6dfa9c8fe37d5706d95ce81012b8db3c3b9 Mon Sep 17 00:00:00 2001 From: Even Rouault Date: Wed, 22 Jan 2020 18:31:26 +0100 Subject: Merge RFC4 (#1865) This commit is the result of the squashing of rfc4_dev branch in a single commit. It implements mostly RFC 4 related work. * Grid handling: - remove obsolete and presumably unfinished implementation of grid catalog functionality - all grid functionality is in grids.cpp/.hpp - vertical and horizontal grid shift: rework to no longer load whole grid into memory - remove hgrids and vgrids member from PJ structure, and store them in hgridshift/vgridshift/deformation structures - build systems: add optional libtiff dependency. Must be explicitly disabled if not desired - add support for horizontal and vertical grids in GeoTIFF, if libtiff is available - add GenericShiftGridSet and GenericShiftGrid classes, relying on TIFF grids, that can be used for generic purpose grid-based adjustment - add a +proj=xyzgridshift method to perform geocentric translation by grid. Used for French NTF to RGF93 transformation using gr3df97a.tif grid - deformation: add support for +grids= for GeoTIFF grids - horizontal grid shift: fix failures on points slightly outside a subgrid (fixes #209) * File management: - add a filemanager.cpp/.hpp to deal with file related work - test for legacy proj_api.h fileapi - proj.h: add proj_context_set_fileapi() and proj_context_set_sqlite3_vfs_name() (fixes #866) - add capability to read resource files from the user writable directory * Network access: - build systems: add optional curl dependency - add a curl-based default implementation for network related functionality - proj.h: add C API to control network functionality, and optionaly provide network callbacks - add data/proj.ini with default settings - add a SQLite3 local cache of downloaded chunks - add proj_is_download_needed() and proj_download_file() * Use Win32 Unicode APIs and expect all strings to be UTF-8 (fixes #1765) For backward compatibility, if PROJ_LIB content is found to be not UTF-8 or pointing to a non existing directory, then an attempt at interpretating it in the ANSI page encoding is done. proj_context_set_search_paths() now assumes strings to be in UTF-8, and functions returning paths will also return values in UTF-8. --- data/proj.ini | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 data/proj.ini (limited to 'data/proj.ini') diff --git a/data/proj.ini b/data/proj.ini new file mode 100644 index 00000000..0ae33249 --- /dev/null +++ b/data/proj.ini @@ -0,0 +1,16 @@ +[general] +; Lines starting by ; are commented lines. +; + +; Network capabilities disabled by default. +; Can be overriden with the PROJ_NETWORK=ON environment variable. +; network = on + +; Can be overriden with the PROJ_NETWORK_ENDPOINT environment variable. +cdn_endpoint = https://cdn.proj.org + +cache_enabled = on + +cache_size_MB = 300 + +cache_ttl_sec = 86400 -- cgit v1.2.3
