after some discussion on discord with the libjxl maintainers
see https://github.com/libvips/libvips/issues/2830
to do: save scrgb to eg. JPEG fails right now :( we need to do
scRGB->sRGB in jpegsave
- Remove `HAVE_LCMS` definition in favor of `HAVE_LCMS2`.
- Remove `HAVE_WINDOWS_H` definition in favor of `G_OS_WIN32`.
- Remove stray `vips_text_get_type` in `conversion.c`.
- Remove duplicated `unistd.h` include.
- Remove redundant `strcasecmp` definition, we use `g_ascii_strcasecmp` everywhere.
- Remove unnecessary header checks in `configure.ac` and `meson.build`.
- Ensure `unistd.h` include is guarded with `HAVE_UNISTD_H`.
- Fail early when `-Dfontconfig=enabled` and `pangoft2` is not found.
Use the bitwise OR assignment operator to ensure that derived
classes does not overwrite the flags from the base class. Also,
move the flags from `openslideload_source` to its base class.
* flag to save bmp with bitdepth 1
* magicksave: add bitdepth option
* update comments
* update documentation
* revised based on review comments

We were calling it a sum and looking for a change threshold, but really
it's only useful as a checksum and does not have a magnitude. Revise
comments and variable names to reflect this.
* save GIF palette as metadata
... if there are no local colour tables.
See https://github.com/libvips/libvips/issues/2576
* cgifsave: reuse global palette, if possible
* add reuse_palette parameter
* add reoptimise parameter and reuse palette by default
* attach global palette even if local palettes are present
* add check for presence of use-lct
* Revert "add check for presence of use-lct"
This reverts commit cd0f14e45e8bed8f108ee9666e2569c6355f17eb.
* Revert "attach global palette even if local palettes are present"
This reverts commit 4085b9e14b73c8990e9653ccc6f90477c2a43032.
* move global palette quantization to cgif_build
* rename member variable gct
* update comments
* improve error handling
* update documentation

This ensures child processes do not inherit open file descriptors
and will close a small but long-standing bug reported against
sharp over five years ago.
The change to lcms2 to support this is backwards compatible so
the flag will be ignored by existing versions.
The fopen 'e' flag will soon be part of the POSIX standard, and
is already supported in Linux and BSD. macOS currently ignores
it but will add support soon. Only Windows has a problem with it,
hence the ifdef wrapper.
* start adding dzsave to a target
made a thing for gsf to write to a target
* fix stray tabs in dzsave
* fix dzsave write to "."
Early versions of libgsf did not support writing to ".", so we had an ugly
workaround, but this should now be OK.
Fixing this ought to make write to target simple
* dzsave_target compiles
no idea if it works though
* seems to work now
creates stray 0 length files though, very odd
* fix stray files from dzsave
next: save to buffer is returning null
* fix buffer flush in dzsave
all tests pass!
* update changelog
* compiles, but untested
* works, but libtiff needs seek for write
next: add seek methods to target
* add target seek and read
seem to work
next: disc temps for disc output
* add libnsgif COPYING
oops, we were missing the COPYING file
see https://github.com/libvips/libvips/issues/2800
thanks mika-fischer
* tiffsave uses a disc temp if it can
* revise temp target rules
only make a disc temp if we are writing to a filesystem target
* add new target methods to targetcustom
since finish did not return an error code
also make sure we don't call target_end from inside _dispose, since that
can't signal error either
see https://github.com/libvips/libvips/issues/2801
* Allow to modify/create EXIF 2.3 ASCII tags
Make `tag_is_ascii` aware of the EXIF 2.3 ASCII tags that are
available since libexif 0.6.22.
See: https://github.com/kleisauke/net-vips/issues/167
* Fix CI
* quick proposal
warn on startup if untrusted operations might run
use vips_block_untrusted_set() to block untrusted operations, set an env
var or make a file to stop the warning
* mark fits, nifti and svg as untrusted
* remove the annoying "untrusted" warning message
better to warn on the download page
leave vips_block_untrusted_set() since it's obviously useful
* separate UNTRUSTED and BLOCKED
* typos
* add VIPS_BLOCK_UNTRUSTED env var
* move BLOCK_UNTRUSTED after plugin load
obviously, ooops
* add a test, disable *magick
although *magick is fuzzed, it's probably safer to disable it in
untrusted environments
* mark some more operations as untrusted
Strip TIFFs with rowperstrip of 1 used to use 1-pixel high cache tiles.
This could slow reading. This patch sets a minimum tile height near 16
but a multiple of the strip size.
* libnsgif: Update to latest upstream.
* nsgifload: Update for new pixel format API.
LibNSGIF now lets the client select a pixel colour component
order. We use NSGIF_BITMAP_FMT_R8G8B8A8, which is the same
format LibNSGIF always decoded to.
* nsgifload: Remove loop_count from VERBOSE output.
This was internal state for a nsgif_frame_prepare() managed
animation, but VIPS doesn't use nsgif_frame_prepare(). The
loop_count member has been removed from the public structure.
The nsgif_data_scan() call returns an error code that says
if anything was wrong with the source data.
It is not unusual for there to be bad stuff in a GIF, so we
only need to worry if we failed to find any frames.
* cgifsave: avoid size issue
avoid size issue by restoring the original transparency setting after quantization/dithering
* switch to per-frame alpha channel
* add option for lossy transparency
* switch lossy transparency off by default
* switch to g_malloc instead of g_malloc0
no need to 0 initialize at this point
* adapt to libvips coding conventions
* cgifsave: avoid size issue
avoid size issue by restoring the original transparency setting after quantization/dithering
* switch to per-frame alpha channel
* add option for lossy transparency
* switch lossy transparency off by default
* switch to g_malloc instead of g_malloc0
no need to 0 initialize at this point
* adapt to libvips coding conventions
* switch to official Homebrew sources for installing cgif
* bump required cgif version to v0.2.0
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.
* Meson: remove space before colon
Since key-value pairs in Python are usually delimited as
colon+space instead of space+colon+space.
* Meson: disable modules by default when building static libraries
Corresponds to autotools. See: #2323.
* Meson: make modules a feature option
Corresponds to autotools, where modules are built
automatically if enabled and supported.
* Meson: specify minimum required GLib version
* Meson: fix indentation
* Remove unused function checks
* Simplify GLib configure checks
* Meson: ensure modules doesn't include enumtypes sources
Since that would cause duplicate symbols.
(`soname_header` can also be safely removed here,
since that is already included in `libvips_headers_dep`)
* LSan: remove GLib suppression
* LSan: disable the fast unwinder to get full stacktraces
* Move ASan/UBSan fuzzer options to CI configuration
* LSan: remove EOLed python2.7 suppression
* LSan: remove libstdc++ suppression
* LSan: add libx265 to suppression file
* Try to reproduce small memleak
* Try a possible patch
* Skip test if `im_benchmark` is not available
* CI: upgrade Clang version to 13
* CI: correct job names
* Meson: increase the timeout for tests
* README.md: correct Meson invocation
* Ensure that double asterisk characters are only used for gtk-doc comments
This triggers warnings when parsing the files with the introspection scanner
and gtk-doc
* Enhance the introspection support by fixing annotations
Also refine the .metadata file
