* Add DNG tags up to version 1.6.0.0 and some TIFF/EP tags and update ↵Su_Laus2023-04-251-1/+1
| | | | | | | | | | | documentation Amend MR !337 'Add support for DNG tags up to version 1.6.0.0 and some TIFF/EP tags' from Sami Liedes: - Set most tags to OkToChange=1. - Define BATTERYLEVEL tag as ASCII and convert values of rational variant to ASCII. - TIFF documentation updated for tags recognized by LibTiff (DNG 1.6 and others). - TIFF/EP tags added, which are equivalent to EXIF tags. This addresses part of #418 as well. - Definition of tags reformatted (clang-format off) for better readability of tag comments in tiff.h and tif_dirinfo.c

* test (cmake): skip script tests if tools aren't builtSam James2023-02-221-81/+85
| | | | | | | | | | | In Gentoo, we avoid building the tools for multilib (32-bit, x86) builds on amd64/x86_64 because we only need the library to keep binary applications working. This causes a test failure in e.g. tiffcp-thumbnail.sh as the 'thumbnail' binary isn't built. Skip it if unavailable.

* Fix CMake build to be compatible with FetchContentJeremy Maitin-Shepard2022-10-031-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of CMake have improved support for including dependencies, using the FetchContent module, which allows a dependency to be imported as a subproject and then later found automatically by calls to `find_package`. This change makes libtiff's CMake better behaved when used as a sub-project: - CMake has a single global namespace for all target names in all sub-projects. This commit renames the following CMake targets: - port -> tiff_port - mkg3states -> tiff_mkg3states - faxtable -> tiff_faxtable - release -> tiff_release - When building TIFF as a sub-project, it is not normally useful to create install rules for its targets. This commit adds a `tiff-install` option that controls whether the install rules are added and defaults to OFF when libtiff is included as a sub-project. - Previously, libtiff set `BUILD_SHARED_LIBS` to ON by default. With this commit, that default is only set if libtiff is the top-level project. - When using `find_package(TIFF)`, the targets `TIFF::TIFF` and `TIFF::CXX` are defined. This commit makes libtiff itself define those targets as aliases, to allow other cmake projects to use either `find_package` or `FetchContent` interchangeably. - Adds ZSTD_HAVE_DECOMPRESS_STREAM variable which may be set to bypass `check_symbol_exists` call. Fixes https://gitlab.com/libtiff/libtiff/-/issues/472.

* cmake: allow running the tests with a read-only source directoryAlex Richardson2022-05-151-1/+3
| | | | | | | | | | | | | | Prior to this commit CTest would invoke all simple_tests tests with the current working directory set to the source directory. However, some of the tests (e.g. rewrite) will output files to the current working directory and will therefore fail when run with a read-only source directory. This can happen e.g. when testing a cross-compiled version of libtiff where the sources are mounted read-only in the virtual machine. Simply changing the working directory to CMAKE_CURRENT_BINARY_DIR allows all but raw_decode to pass. The raw_decode test looks for files in the source directory, and uses the `srcdir` environment variable to find, so we also have to add a set_tests_properties() call to specify that env var.

* tif_dirwrite.c: Fix TIFFRewriteDirectory discarding directoriesFacundo Tuesca2021-09-051-15/+100
| | | | | | | | | | | | | | This fixes a bug caused by the `tif_lastdiroff` optimization when rewriting directories. Rewriting the Nth directory temporarily zeroes the pointer to it (located in the N-1th directory) and relies on `TIFFLinkDirectory` traversing the whole directory list to find the zeroed pointer and linking the rewritten directory to it. Since `TIFFLinkDirectory` skips the traversal when `tif_lastdiroff` is set, this change unsets it to force the full traversal when rewriting a directory. A test to catch this particular issue is also added.

* Add field to keep track of last written directoryFacundo Tuesca2021-08-283-2/+247
| | | | | | | | | | | | | | This adds a new `tif_lastdiroff` field to the TIFF data structure and uses it to store the offset of the last written directory. Appending a new directory required traversing the whole file to find the last directory. By keeping track of its offset in this new field, the search is no longer necessary. Since this offset is only stored in-memory, the first directory append after opening a file will have to transverse the whole directory list. Subsequent calls will have access to the last offset, avoiding the transversal.
