This is an attempt to fix#12333 where from the look of the trace, the
segfault may happen if it tries to dereference a NULL view->priv->shell
whereas we have a view->priv->cursor_image. Even though I couldn't
reproduce, I'm wondering if it may possible to have no active image
display while the cursor is indeed hovering an image.
Furthermore this updated code is more logical anyway, because we should
use the "show all" value from the actual display shell the cursor is
hovering, not from the active display shell.
This fixes all our GObject Introspection issues with GimpUnit which was
both an enum and an int-derived type of user-defined units *completing*
the enum values. GIR clearly didn't like this!
Now GimpUnit is a proper class and units are unique objects, allowing to
compare them with an identity test (i.e. `unit == gimp_unit_pixel ()`
tells us if unit is the pixel unit or not), which makes it easy to use,
just like with int, yet adding also methods, making for nicer
introspected API.
As an aside, this also fixes#10738, by having all the built-in units
retrievable even if libgimpbase had not been properly initialized with
gimp_base_init().
I haven't checked in details how GIR works to introspect, but it looks
like it loads the library to inspect and runs functions, hence
triggering some CRITICALS because virtual methods (supposed to be
initialized with gimp_base_init() run by libgimp) are not set. This new
code won't trigger any critical because the vtable method are now not
necessary, at least for all built-in units.
Note that GimpUnit is still in libgimpbase. It could have been moved to
libgimp in order to avoid any virtual method table (since we need to
keep core and libgimp side's units in sync, PDB is required), but too
many libgimpwidgets widgets were already using GimpUnit. And technically
most of GimpUnit logic doesn't require PDB (only the creation/sync
part). This is one of the reasons why user-created GimpUnit list is
handled and stored differently from other types of objects.
Globally this simplifies the code a lot too and we don't need separate
implementations of various utils for core and libgimp, which means less
prone to errors.
This one is kind of a huge deal, because the info returned by the color frame
was kind of messy (even though it improved lately, but space associated to color
data had to be kept in-sync by hand, which was bug-prone).
Now the color frame stores the data as a GeglColor, always aware of its space
and therefore able to do much nicer conversion. Also RGB and Grayscale options
now display the profile name of the color space (until now, we had only this for
the CMYK option using the proofing profile).
I still wish to get more options. Typically some people may want to get
RGB/Grayscale/CMYK values to other spaces (maybe sRGB, one of their favorite
profile as set in Preferences or just any random profile which they could load
from disk). Giving such ability to basically live-convert their pixel data to
various other color space would be very nice. We'll see if this will be
implemented for GIMP 3 or for after.
This is a first commit to really getting rid of GimpRGB within core and
PDB/plug-in code. This will make color conversion reliability a lot better as
GeglColor will handle conversions for us. The goal is that we should keep origin
color space (for instance when picking colors in a GimpPickable, or when storing
in the FG/BG colors or in paletters) until the last second and convert at use
only.
It's still very much work-in-progress.
Wherever we store arbitrary-format colors in an opaque buffer, use
double for the buffer, instead of char, so that it has a strict-
enough alignment to handle all our used pixel formats.
and remove a gazillion gtk_widget_show() all over the place, some
places need a gtk_widget_hide() now, and I'm pretty sure I broke at
least one thing in all those files...
Add a show_all parameter to gimp_image_pick_color(), which, when
TRUE, allows picking colors outside the canvas bounds in sample-
merged mode. Forward the display's "show all" mode through this
parameter where applicable (in particular, in the color-picker tool
and the pointer dockable).
... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
Add "ellipsize" property to GimpColorFrame and set it to
PANGO_ELLIPSIZE_END in the the pointer information dockable.
Better cut off long numbers than make them expand the dock.
Updating the cursor information involves sampling the active image/
drawable, which can be expensive, especially if there are filters
active that also respond to cursor motion, e.g., while using the
warp tool.
Move the actual updating to an idle function. This dramatically
improves responsiveness in these situations.
gimp_unit_get_digits() won't return relevant information when using
higher resolution. gimp_unit_get_scaled_digits() will provide the right
amount of details relatively to the actual print resolution of the
active image.
...regardless of image color precision
Split enum value GIMP_COLOR_FRAME_MODE_RGB into RGB_PERCENT and RGB_U8,
which display the current % values, and values in a range of 0..255.
Convert GimpRGB to CMYK using a color transform to the configured CMYK
profile instead of the naive gimp_rgb_to_cmyk().
Add gimp_color_frame_set_color_config() and call it on all color
frames in the GUI (color picker tool, cursor info, sample point view).
Keep a GimpColorTransform around that does the conversion.
Also color manages the frame's color area now (visible in the sample
point view), which was forgotten earlier. Addresses bug #467930.
...when a color profile is active
This commit doesn't fix anything, but it prepares the code to do the
right thing:
It passes the actual raw image pixels through the entire color picking
mechanism to the widgets which display colors, particularly
GimpColorFrame.
This is needed for GimpColorFrame's "Pixel" mode (as opposed to its
RGB, HSV etc. modes) which is supposed to show the raw pixel values
from the image.
Before this commit, it was recreating the raw pixel values from the
GimpRGB value it knows, which will become impossible when we correctly
pick color managed GimpRGB values soon.
and get rid of the brainfuck idea that app/ has to use _gimp_unit_foo()
functions, passing a gimp pointer. Instead, simply use the libgimpbase
API all over the place. Should we ever allow more than one gimp instance,
they will simply have to share one unit database.
