- rename compression_level as deflate_level to match libgsf convention
- use libgsf enums for GSF_ZIP_STORED, etc.
- configure-time checks for zip64 and deflate-level
- off-topic: rename NEED_TYPE_INIT as HAVE_TYPE_INIT for consistency
This is the first version that works properly with gtk3. Lowering the
requirement enables SVG support on older Linux distributions like
Ubuntu Precise LTS or Debian Wheezy.
* Do not warn when the prefix appears to be a homebrew cellar.
* Fix configure errors when python is not detected
* Fix configure errors when pygobject is installed in prefix but
not present in the python `sys.path`.
* Use the actual overrides path, instead of the gi module path.
The python.m4 that ships with automake hardcodes the library path for
platfrom dependent files to `lib`, which is wrong for multiarch systems.
Instead we import the `m4/python.m4` from pygobject, which does not have
this problem and also ensures we have the same behavior as pygobject
which we are depending on for pyvips8.
Due to this change some minor changes to how the `bootstrap.sh` script
clean up the `m4` folder where needed.
The python search order has been modified to prefer the default python
over python2 over python3.
This fixes the poppler-glib version requirement to version 0.16, which
is the lowest version that compiles and works properly with pdfload.
Also added a check for pdfload and enabled testing on Travis CI.
* Add configure check for libwebp >= 0.1.3
* Add custom memory writer using GNOME memory allocation
* Add various ABI checks and warnings for unsupported features:
** smart_subsample and near_lossless require 0.5.0
** lossless requires at least 0.1.99
GM is still using the old page interface of subimage/subrange, IM has
deprecated that in favour of scene/number_scenes
we were accidentally just supporting the new IM system ... this change
adds support for GM as well, plus a configure test to pick one
see https://github.com/jcupitt/libvips/issues/423
vips has built-in support for rad, analyze and ppm ... add configure
switches to disable these readers
useful to reduce the attack surface in some applications
it was getting too hard to support :( automake now generates libtool
lines before configure runs, so it can't know we don't want a C++ link
see https://github.com/jcupitt/libvips/issues/231
