2020-11-20Remove old pj_ memory (de)allocation functionsKristian Evers
Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary function as API memory functions in proj_api.h is no longer there and the other use as a workaround for old errno problems is no longer valid either. Replaced with malloc and free across the codebase.

2020-01-22Merge RFC4 (#1865)Even Rouault
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.
2019-11-25pipeline.cpp: use more explict variable namesEven Rouault
2019-11-25Pipeline: support +omit_fwd and +omit_inv keywordsEven Rouault
Inspired from syntax of https://github.com/OSGeo/PROJ/pull/453/files but 'rebased' on top of previous commit that cleans up the pipeline implementation Different situations: - +omit_fwd: the step when followed in the forward path will be omitted the step when followed in the reverse path will be executed - +omit_fwd +inv: the step when followed in the forward path will be omitted the step when followed in the reverse path will be executed (with the inv method) - +omit_inv: the step when followed in the forward path will be executed the step when followed in the reverse path will be omitted - +omit_inv +inv: the step when followed in the forward path will be executed (with the inv method) the step when followed in the reverse path will be omitted This will be used in the next commit to optimize constructs like +step +proj=hgridshift +grids=foo +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo Such steps are used for CRS to CRS transformations where applying the vertical grid requires to do a transformation to an interpolating CRS. One can notice that in the last step will just restore the horizontal coordinates before the first step, so doing an inverse hgridshift is overkill. So that could be optimized as: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +omit_inv +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo +omit_fwd +step +proj=pop +v_1 +v_2 In the forward path, this will be equivalent to: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +step +proj=vgridshift +grids=bar +step +prop=pop +v_1 +v_2 And similarly in the reverse path, this will be quivalent to: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +step +inv +proj=vgridshift +grids=bar +step +proj=pop +v_1 +v_2
2019-11-24pipeline.cpp: hopefully make code more readable by using more C++ goodness. ↵Even Rouault
No functional change intended (except a likely minor correction/improvement in get_next_non_whatever_unit in the PJ_INV case where the iteration should start at step-1)
2019-11-12Fix proj_assign_context()/pj_set_ctx() with pipelines and alternative coord ↵Even Rouault
operations Fixes https://github.com/OSGeo/gdal/issues/1989 pj_set_ctx() only changes the context to the main object. It should also recurse down to the steps of the pipeline and the alternative coordinate operations hold in alternativeCoordinateOperations In the GDAL use case with multithreaded reprojection, and objects being transferred between thread, this would cause a failed coordinate transformation to affect an unrelated transformation of another thread...
2019-09-22Update to version 1.50 of the geodesic library.Charles Karney
* Allow arbitrarily complex polygons in geod_polygon_*. In the case of self-intersecting polygons the area is accumulated "algebraically", e.g., the areas of the 2 loops in a figure-8 polygon will partially cancel. * Simplify code by using C99 functions remainder and remquo. * More test coverage. Fixes to associated files: * src/pipeline.cpp invoke geod_init with f = es / (1 + sqrt(1 - es)) instead of (the less accurate) f = 1 - sqrt(1 - es) * src/apps/geod_set.cpp remove "#undef f" (a dangling relic?).

Introduced by "Merge projects.h into proj_internal.h" 8ab6f683.
2019-02-13Add push and pop operationsKristian Evers
This commit introduces the concept of a pipeline coordinate stack in which components of coordinates can be saved and loaded from. This makes it possible to moved values from one step of a pipeline to another, effectively overwriting parts of the output from a given step.
