This commit completely removes the "Edit -> Fade..." feature,
because...
- The main reason is that "fade" requires us to keep two buffers,
instead of one, for each fadeable undo step, doubling (or worse,
since the extra buffer might have higher precision than the
drawable) the space consumed by these steps. This has notable
impact when editing large images. This overhead is incurred even
when not actually using "fade", and since it seems to be very
rarely used, this is too wasteful.
- "Fade" is broken in 2.10: when comitting a filter, we copy the
cached parts of the result into the apply buffer. However, the
result cache sits after the mode node, while the apply buffer
should contain the result of the filter *before* the mode node,
which can lead to wrong results in the general case.
- The same behavior can be trivially achieved "manually", by
duplicating the layer, editing the duplicate, and changing its
opacity/mode.
- If we really want this feature, now that most filters are GEGL
ops, it makes more sense to just add opacity/mode options to the
filter tool, instead of having this be a separate step.
Add a boolean "direct" parameter to gimp_projection_flush_now(),
which specifies if the projection buffer should only be invalidated
(FALSE), or rendered directly (TRUE).
Pass TRUE when flushing the projection during painting, so that the
affected regions are rendered in a single step, instead of tile-by-
tile. We previously only invalidated the projection buffer, but
since we synchronously flush the display right after that, the
invalidated regions would still get rendered, albeit less
efficiently.
Likewise, pass TRUE when benchmarking the projection through the
debug action, and avoid flushing the display, to more accurately
measure the render time.
It was not doing anything right since space invasion. We now treat the
built-in sRGB profile like any other profile and never bypass
conversions based on some weird toggle.
Instead, introduce a "Use sRGB Profile" toggle which, when enabled,
hides whatever profile away so the image actually uses the built-in
sRGB profile.
This is different from discarding and then re-assigning the same
profile only by being faster and more convenient.
... to make multi-color hard-edge gradient fills possible
Add a new "step" gradient-segment blending function, which is 0
before the midpoint, and 1 at, and after, the midpoint. This
creates a hard-edge transition between the two adjacent color stops
at the midpoint. Creating such a transition was already possible,
but required duplicating the same color at the opposing ends of two
adjacent stops, which is cumbersome.
Add an option to record a performance log through the dashboard.
The log contains a series of samples of the dashboard variables, as
well as the full program backtrace, when available. As such, it
essentially acts as a built-in profiler, which allows us to
correlate program execution with the information available through
the dashboard. It is meant to be used for creating logs to
accompany perofrmance-related bug reports, as well as for profiling
GIMP during development.
The sample frequency defaults to 10 samples per second, but can be
overridden using the GIMP_PERFORMANCE_LOG_SAMPLE_FREQUENCY
environment variable. Backtraces are included by default when
available, but can be suppressed using the
GIMP_PERFORMANCE_LOG_NO_BACKTRACE environment variable.
Logs are created through the new "record" button at the bottom of
the dashboard dialog. When pressed, a file dialog is opened to
select the log file, and, once confirmed, data is being recorded to
the selected file. Recording is stopped by pressing the "record"
button again (we use a highlight to indicate that recording is
active.)
While recording, the "reset" button is replaced with an "add marker"
button, which can be used to add event markers to the log. These
can be used to mark events of interest, such as "started painting"
and "stopped painting", which then appear in the log as part of the
sample stream. Markers are numbered sequentually, and the number
of the next (to-be-added) marker appears on the button. Shift-
clicking the button adds an empty (description-less) marker, which
is only identified by its number; this can be used when markers
need to be added quickly.
The log is an XML file, containing some extra information (such as
the output of "$ gimp -v", and symbol information) in addition to
the samples. The data in the file is delta-encoded to reduce the
file size, meaning that samples (as well as some other elements)
only specify the changes since the previous sample. This adds a
necessary decoding step before data can be processed; the next
commit adds a tool that does that.
There are currently no tools to actually analyze the data -- that's
still TBD -- but at least we can start gathering it.
This is my attempt to get better labels, shorter and also (hopefully)
improved English.
As Mitch states though, this is a Japanese-French-German conspiracy! So
any of you native English speakers out there, please review and suggest
proper English if needed. :-)

All babl formats now have a space equivalent to a color profile,
determining the format's primaries and TRCs. This commit makes GIMP
aware of this.
libgimp:
- enum GimpPrecision: rename GAMMA values to NON_LINEAR and keep GAMMA
as deprecated aliases, add PERCEPTUAL values so we now have LINEAR,
NON_LINEAR and PERCPTUAL for each encoding, matching the babl
encoding variants RGB, R'G'B' and R~G~B~.
- gimp_color_transform_can_gegl_copy() now returns TRUE if both
profiles can return a babl space, increasing the amount of fast babl
color conversions significantly.
- TODO: no solution yet for getting libgimp drawable proxy buffers in
the right format with space.
plug-ins:
- follow the GimpPrecision change.
- TODO: everything else unchanged and partly broken or sub-optimal,
like setting a new image's color profile too late.
app:
- add enum GimpTRCType { LINEAR, NON_LINEAR, PERCEPTUAL } as
replacement for all "linear" booleans.
- change gimp-babl functions to take babl spaces and GimpTRCType
parameters and support all sorts of new perceptual ~ formats.
- a lot of places changed in the early days of goat invasion didn't
take advantage of gimp-babl utility functions and constructed
formats manually. They all needed revisiting and many now use much
simpler code calling gimp-babl API.
- change gimp_babl_format_get_color_profile() to really extract a
newly allocated color profile from the format, and add
gimp_babl_get_builtin_color_profile() which does the same as
gimp_babl_format_get_color_profile() did before. Visited all callers
to decide whether they are looking for the format's actual profile,
or for one of the builtin profiles, simplifying code that only needs
builtin profiles.
- drawables have a new get_space_api(), get_linear() is now get_trc().
- images now have a "layer space" and an API to get it,
gimp_image_get_layer_format() returns formats in that space.
- an image's layer space is created from the image's color profile,
change gimpimage-color-profile to deal with that correctly
- change many babl_format() calls to babl_format_with_space() and take
the space from passed formats or drawables
- add function gimp_layer_fix_format_space() which replaces the
layer's buffer with one that has the image's layer format, but
doesn't change pixel values
- use gimp_layer_fix_format_space() to make sure layers loaded from
XCF and created by plug-ins have the right space when added to the
image, because it's impossible to always assign the right space upon
layer creation
- "assign color profile" and "discard color profile" now require use
of gimp_layer_fix_format_space() too because the profile is now
embedded in all formats via the space. Add
gimp_image_assign_color_profile() which does all that and call it
instead of a simple gimp_image_set_color_profile(), also from the
PDB set-color-profile functions, which are essentially "assign" and
"discard" calls.
- generally, make sure a new image's color profile is set before
adding layers to it, gimp_image_set_color_profile() is more than
before considered know-what-you-are-doing API.
- take special precaution in all places that call
gimp_drawable_convert_type(), we now must pass a new_profile from
all callers that convert layers within the same image (such as
image_convert_type, image_convert_precision), because the layer's
new space can't be determined from the image's layer format during
the call.
- change all "linear" properties to "trc", in all config objects like
for levels and curves, in the histogram, in the widgets. This results
in some GUI that now has three choices instead of two.
TODO: we might want to reduce that back to two later.
- keep "linear" boolean properties around as compat if needed for file
pasring, but always convert the parsed parsed boolean to
GimpTRCType.
- TODO: the image's "enable color management" switch is currently
broken, will fix that in another commit.
Registering a full menu path as a procedure's menu label is now
forbidden and causes the procedure to be rejected.
Bump the plug-in protocol version so a pluginrc containing such cruft
is not used.
This is using GTK+3 widgets, so I make sure to keep it well separated
from core code. The gimp-2-10 version will have to rework the GUI, but
the GtkListBox and GtkSwitch are nice and make things easier, so it is
worth using them here).
Let the split and replicate segments dialogs keep their own data and
don't use GimpGradientEditor struct members. Remove redundant members
and indent the struct.
Return an optional tooltip from gimp_procedure_get_sensitive(), in
GimpPlugInProcedure, build that tooltip from the image types the
procedure works on.
Instead just transform the measurement extremities appropriately to
still map to the same points.
To do so, I also added out parameters to gimp_image_resize_to_layers()
so that calling code can get offsets from old origin (as well as new
image dimensions).
We already avoid rendering text layers while fonts are loading,
showing an appropriate message, but this will soon be replaced with
waiting for the fonts to finish loading.
Instead, don't allow the text tool to start at all while the fonts
are loading (showing an appropriate tool message, and a BAD cursor
modifier), and halt the tool when reloading fonts if it's already
started.
Fonts should not be blocking startup as this provides a very bad
experience when people have a lot of fonts. This was experienced even
more on Windows where loading time are often excessively long.
We were already running font loading in a thread, yet were still
blocking startup (thread was only so that the loading status GUI could
get updated as a feedback). Now we will only start loading and proceed
directly to next steps.
While fonts are not loaded, the text tool will not be usable, yet all
other activities can be performed.
Remove all clipping hacks for drawing the canvas background, turns out
they never worked and we were relying on the pattern set on the
window, gah!
Also remove deprecated attempts to get a backgroud color and simply
don't show a color box in the menus for "from theme" cases.
The zoom focus discussion on IRC suggests that everybody is annoyed
about centering behavior (or lack thereof), so here is a way to
explicitly center the image witout zooming.
