.. due to gdk_pixbuf_scale() with themes using the pixbuf engine
Make GimpDisplayShell a subclass of GtkEventBox, so that it gets its
own window, isolating its events from those of its ancestors.
In particular, the "expose" event handler of GtkNotebook, which the
shell is a child of in SWM, is particularly slow with themes that
use the pixbuf engine. If the notebook and the shell use the same
window, this can cause notable, and somtimes severe, lag when the
rulers or scrollbars are updated frequently, such as when rapidly
moving the cursor.
which encapsulates a cmsHTRANSFORM and does all the pixel format
conversion magic. It has API to create transforms and proofing
transforms, and to convert pixels arrays and GeglBuffers.
Before, each place which has a transform had to keep around the
transform and its input and output Babl formats, and had to implement
lots of stuff itself. Now all that lives in GimpColorTransform,
removing lots of logic from many places, and pretty much removing lcms
from the public API entirely.
This removes including <lcms2.h>, LCMS_LIBS and LCMS_CFLAGS from
almost all directories and potentially allows to replace lcms by
something else.
Add a View -> Color Management submenu that allows to change
the color management mode per-display.
Internally, keep a GimpColorConfig object around per-display that
is synchronized with the global config except for the properties
that have a per-display GUI (currently the mode).
Also provide an "As in Preferences" menu item to follow the global
settings again.
Use the shell's color config for color managing the display and
various auxiliary widgets attached to it, like the notebook tab widget
and navigation popup.
The config is currently just a reference to the global prefs config,
so no behavior changed.
Change gimp_get_display_name() to also return the screen, and its
implementation in the GUI to return the initial monitor during
startup. Retrieve that information in app.c using a weird callback
construct and pass the monitor to file_open_from_command_line().
Half-related, add screen and monitor parameters to GimpDisplayShell
and use these initial values for calculating the canvas's initial
extents.
The image windows still don't position themselves correctly though
because we have no mechanism for that whatsoever just yet, but we now
at least pass the needed monitor information to the right objects.
Disable extended input events when the cursor moves to a child of
the canvas widget. Otherwise GTK will try and fail to deliver an
extended event to the child widget, and end up sending it to the
canvas instead.
Along with this change, the snap preferences have been moved from
GimpDisplayConfig to GimpDisplayOptions, where it makes much more sense.
One of the consequences is that there is no need to duplicate these
values in GimpDisplayShell anymore to differenciate defaults and
current settings.
This removes the obsolete check which makes the tool fail from
gimp_display_shell_set_mask(). Also change the foreground select tool
and the display mask from using GimpChannel to GeglBuffer, because
that's what it needs, simply buffers. Most changed files simply newly
include <gegl.h> because a GeglBuffer appeared in two headers.
First version of display rotation, inspired by gimp-painter.
The rotation always happens around the image's center.
The only "UI" for rotating is currently shift+middle-drag and
shift+space-drag. Control constrains the angle to 15 degrees
and is currently the only way to go back to "no rotation".
and don't use them for (un)transforming integer coordinates. Everything
seems to work fine, but this sort of change has caused off-by-one errors
before, please review.
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).

Because it's generally the right thing to do, and server grabs broke
badly with input devices / client side windows.
gimpdisplayshell-grab.c: change logic to only server-grab if an event
is passed to the pointer grab/ungrab functions, but always use
gtk_grab_add/remove() which is sufficient in most cases.
gimpdisplayshell-tool-events.c: have the grab functions grab the
server only for space-bar scrolling and do all tool interaction,
including ruler clicks, with gtk_grab_add/remove(). Refactor things
a bit to also use the grab API for button-2 scrolling.
gimpdeviceinfo-coords.c: transform the event's coords to the canvas'
coordinate system, they might come from a ruler now.
This fixes the following bugs:
Bug 645315 - gimp_display_shell_pointer_grab: gdk_pointer_grab failed...
Bug 644351 - Gimp misses some strokes especially when drawing fast
Bug 645747 - Gimp is now unusable on xfce4
Add a canvas item group for previews, and a small preview infrastructure
to GimpDrawTool, and put the transform preview into the preview group,
which is below all guides, grid and layer boundaries.
This commit only adds the class and removes the members from
GimpDisplayShell, so everything looks more ugly than before, but
I wanted the member moving separate from any refactorings.
and simply *always* set the tool to the right state before sending it
a button_press. GimpTool's state setting functions are now smart
enough to simply ignore setting the same state again. When recieving a
FOCUS_IN, skip state setting when the pointer is grabbed, which is a
safe indicator for tool interaction going on. This hopefully fixes
states for both click-to-focus and focus-follows-mouse *and* fixes the
previously warning case where a new image was opened into an already
focussed canvas (the warning then happened on button press, and the
tool was in an inconsistent state).
And remove all the complicated handling code entirely. This makes
GimpTransformTool a lot less complex. As a nice side effect, the
preview is now always 100% in sync with the grid and handles.
Spit warnings in the functions if grabbing fails and return a boolean
success value. Bail out in the callers upon grab failure instead of
assuming that grabbing always succeeds and running into an
inconsistent state that can cause all sorts of problems.
which is the last bit of non-item drawing of stuff that is not
somehow the image itself... wheee!
This involves reverting commit
6bce0641d4 and adding back all the
vectors handlers that were in gimpdisplayshell-callbacks.c before.
Change the callbacks to manage proxy items for all the image's
vectors.
and use it to draw the layer boundary. Remove a lot of stuff
that was there only to draw the boundary before:
- remvoe all layer boundary stuff from the selection code
- remove gimp_display_shell_draw_layer()
- remove enum values GIMP_SELECTION_LAYER_ON,OFF from core-enums.h
- remove all lines calling gimp_image_selection_control() with
the removed enum values
- remove gimp_layer_boundary()
