and build file-uri unconditionally, always using GIO. Use more GFiles
instead of URIs in the plug-in in preparation of moving its
functionality to the core.
Script-fu gettext strings were mostly not extracted by xgettext. This
will be fixed in upcoming gettext 0.19. Add a test to warn packagers
using older gettext.
Don't check for it as if it were optional, and error out further down
in configure.ac. Instead error out immediately and remove all other
checks and Makefile hacks.
Based on original patches from Hartmut Kuhse and modified
by Michael Natterer. Changes include:
- remove libexif dependency and add a hard dependency on gexiv2
- typedef GExiv2Metadata to GimpMetadata to avoid having to
include gexiv2 globally
- add basic GimpMetadata handling functions to libgimpbase
- add image and image file specific metadata functions to libgimp,
including the exif orientation image rotate dialog
- port plug-ins to use the new APIs
- port file-tiff-save's UI to GtkBuilder
- add new plug-in "metadata" to view the image's metadata
- keep metadata around as GimpImage member in the core
- update the image's metadata on image size, resolution and precision
changes
- obsolete the old metadata parasites
- migrate the old parasites to new GimpMetadata object on XCF load
Drop the glib-dbus dependency and port stuff to GDBus. Use it
unconditionally if not on Windows or OSX. It seels to work just like
before but I have no idea if everything is really correct.
This is a basic implementation of an OpenEXR loader. This
"infrastructure" is required for any further work. It consists of:
* The build system changes.
* A C wrapper around the OpenEXR library, which is necessary as it's not
possible to intermix GIMP's code with C++ code.
* A basic image loader. Chroma is not supported currently, and some
other weird files like multi-view files are unsupported. These can be
added when necessary. There is no UI, but it should be straightforward
to add new features like this on top of this work.
Without the dependencies of file-compressor (currently zlib, libbzip2
and liblzma), configure fails now. file-compressor is referenced in too
many places for its functionality to be optional.
Recent Cairo uses SHM transports when available, and exposes the ability
for its users to manage images shared between it and the display.
This allows us to eliminate copies, and if the architecture supports it
even to upload directly into GPU addressable memory without any copies
(all in normal system memory so we suffer no performance penalty when
applying the filters). The caveat is that we need to be aware of the
synchronize requirements, the cairo_surface_flush and
cairo_surface_mark_dirty, around access to the transport image. To
reduce the frequency of these barriers, we can subdivide the transport
image into small chunks as to satisfy individual updates and delay the
synchronisation barrier until we are forced to reuse earlier pixels.
Note this bumps the required Cairo version to 1.12, and please be aware
that the XSHM transport requires bug fixes from cairo.git (will be
1.12.12)
v2: After further reflections with Mitch, we realized we can share the
transport surface between all canvases by attaching it to the common
screen.
v3: Fix a couple of typos in insert_node() introduced when switching
variables names.
v4: Encapsulating within an image surface rather than a subsurface was
hiding the backing SHM segment from cairo, causing it to allocate
further SHM resources to stream the upload. We should be able to use a
sub-surface here, but it is more convenient to wrap the pixels in an
image surface for rendering the filters (and conveniently masking the
callee flushes from invalidating our parent transport surface).
