In particular, this enables grids whose points of intersection
are at the middle of the image's pixels, which is useful for
undistorted painting with odd-sized brushes using tools other than
the pencil.
This commit also changes the grid visibility behavior, so that the
the visibiltiy of horizontal and vertical grid lines (depending on
the zoom level) is independent.
I am still not sure whether custom guides should follow snapping rules.
Yet I could easily imagine you could want some normal guides with
snapping and in the same time symmetry without snapping to axis of
symmetry. So for the time being, let's disable snapping to custom guides
all the time and see if logic could be improved later.
- Move all GimpGuide members to a private struct
- Remove cruft checks for position < 0, we don't keep removed guides
around in the image's guide list since a long time ago
- Add #define GIMP_GUIDE_POSITION_UNDEFINED G_MININT and use that
instead of -1 (this is also a prerequisite for having guides
outside of the image)
Always round grid spacings and offsets to integer precision when
using them for snapping and grid drawing. While we might *want* to
have subpixel precision grids, all the UI is pretending it to be
on pixel boundaries. Make that pretense an fact.
- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will

2005-09-30 Michael Natterer <mitch@gimp.org>
* app/vectors/gimpstroke.[ch]: added stubs of two new snapping
functions.
* app/core/gimpimage-snap.c: removed their #defines here.
2005-04-19 Michael Natterer <mitch@gimp.org>
* app/core/gimpimage-snap.c: bail out early if the coords are
out-of-image plus a border of the snapping epsilon, and not just
out-of-image. Fixes bug #169892.
2005-01-07 Michael Natterer <mitch@gimp.org>
* app/core/gimpimage-snap.c: moved variables to local scopes,
assign the snapped coords unconditionally (also if we don't snap),
cleanup.
(gimp_image_snap_rectangle): entirely rewritten to use local
mindist_x, mindist_y variables instead of fiddling with lots of
boolean variables. Implemented vectors snapping as if the required
GimpStroke functions existed (#defined them). Simon, your turn :)
2005-01-03 Michael Natterer <mitch@gimp.org>
Implemented "Snap to Canvas Edges" (fixes bug #152971) and
"Snap to Active Path" (half way done):
* app/core/gimpimage-snap.[ch]: added boolean snap_to_canvas and
snap_to_vectors parameters (snap_to_vectors works fine when
snapping to a point, but is unimplemented for snapping to a
rectangle).
* app/display/gimpdisplayshell.[ch] (struct GimpDisplayShell):
added snap_to_canvas and snap_to_vectors booleans.
* app/display/gimpdisplayshell-appearance.[ch]: added API to
get/set them.
* app/actions/view-actions.c
* app/actions/view-commands.[ch]
* app/widgets/gimphelp-ids.h: added actions, callbacks and help IDs.
* menus/image-menu.xml.in: added them to Image->View.
2004-02-23 Michael Natterer <mitch@gimp.org>
* app/core/gimpimage-snap.[ch]: return the snapped coordinates as
gdouble, not gint because we must not round the unsnapped axis
if only one axis snapped.
* app/display/gimpdisplayshell.[ch] (gimp_display_shell_snap_coords):
changed accordingly. Added boolean return value indicating "snapped".
* app/display/gimpdisplayshell-cursor.[ch]
(gimp_display_shell_update_cursor): take both display_x and _x and
(possibly snapped) image_x and _y. Use the snapped values for the
statusbar and the unsnapped ones for updating the info_window.
* app/display/gimpdisplayshell-callbacks.c
(gimp_display_shell_canvas_tool_events): applied modified patch
from Simon Budig which moves guide/grid snapping out of the
button_press/motion/button_release handlers and *always* snaps
the image_coords if the active_tool wants them to be snapped.
Makes sure that e.g. the brush preview is drawn at the right
place and fixes bug #134284.
Also pass both display_coords and image_coords to
gimp_display_shell_update_cursor().
2004-02-13 Simon Budig <simon@gimp.org>
* app/core/gimpimage-snap.[ch]: make the snapping width a
parameter of the snapping functions.
* app/display/gimpdisplayshell.c: make sure that the snapping
width always is 5 pixels in the view coordinates.
Fixes bug #134285
2004-01-17 Henrik Brix Andersen <brix@gimp.org>
Finally fixed bug #125864:
* app/core/gimpimage-guides.c (gimp_image_find_guide): iterate
over the entire list of guides to determine the closest one.
* app/core/gimpimage-snap.c: use gdoubles instead of gints for
dist and mindist variables to make sure grid and guides with 1px
spacings work as expected.
2003-11-22 Henrik Brix Andersen <brix@gimp.org>
* gimp/app/core/gimpimage-snap.c: behave correctly for grid
spacing of 1px, whitespace clean up. Fixes the grid part of bug
#125864.
2003-10-06 Michael Natterer <mitch@gimp.org>
Treat changes to the selection like changes to any other drawable:
* app/core/gimpchannel.c
* app/core/gimpchannel-combine.c: call gimp_drawable_update() after
changing the channel.
* app/core/gimpimage.[ch]: added struct GimpImageFlushAccumulator
with one member "gboolean mask_changed". Connect to "update" of
the selection and set accum.mask_changed to TRUE in the callback.
Added default implementation for GimpImage::flush() and emit
"mask_changed" there.
Unrelated:
* app/core/gimpimage.h: removed GimpGuide struct...
* app/core/gimpimage-guides.h: ...and added it here.
* app/core/gimpimage-undo-push.c (undo_pop_mask)
(undo_pop_channel_mod): don't distinguish between selection and
non-selection channels and just call gimp_drawable_update().
* app/core/gimpundo.h
* app/core/gimpimage-undo.c: removed "gboolean mask_changed" from
the GimpUndoAccumulator struct since we don't have to care about
that signal explicitly any more.
* app/display/gimpdisplay-foreach.[ch]: removed gimp_displays_flush().
* tools/pdbgen/pdb/display.pdb (displays_flush_invoker): call
gimp_image_flush() on all images so the flush accumulator is
honored.
This generalization enables the removal of more special purpose
code which was needed to treat the selection different:
* app/core/gimpimage-mask-select.[ch]: removed...
* app/core/gimpchannel-select.[ch]: ...and added under a new name
because it's not selection specific any more.
* app/core/gimpimage-mask.[ch]: removed...
* app/core/gimpselection.[ch]: ...added the two remaining
functions here. Removed all calls to gimp_image_mask_changed().
* app/core/Makefile.am
* app/core/gimp-edit.c
* app/core/gimpdrawable-transform.c

Added persistent storage of image grid in XCF files.
* app/core/gimpimage.[ch]: removed gimp_image_get_grid() and
gimp_image_set_grid() ...
* app/core/Makefile.am
* app/core/gimpimage-grid.[ch]: ... and added them to these new
files. Added gimp_grid_parasite_name(), gimp_grid_to_parasite()
and gimp_grid_from_parasite() functions.
* app/core/gimpimage-snap.c
* app/gui/grid-dialog.c: #include "gimpimage-grid.h"

as a parasite.
* app/xcf/xcf-load.c (xcf_load_image): load GimpGrid from
parasite.

parasite.
This fixes bug #65198
* app/core/Makefile.am

* app/core/gimpgrid.[ch]: added new class GimpGrid.
* app/core/core-enums.[ch]: added new enum GimpGridType.

functions...

are no longer guide specific.

gimp_image_undo_push_image_grid()
* app/display/gimpdisplayshell-handlers.c:

* app/display/gimpdisplayshell-appearance.[ch]: added
gimp_display_shell_set_show_grid(),
gimp_display_shell_get_show_grid(),

* app/display/gimpdisplayshell-callbacks.c: added call to
gimp_display_shell_draw_grid()
* app/display/gimpdisplayshell.[ch]: added grid member to
_GimpDisplayShellVisibility, added snap_to_grid and grid_dialog
members to _GimpDisplayShell, added
gimp_display_shell_draw_grid(), modified
gimp_display_shell_snap_coords() to use the new
gimp_image_snap_*() functions.
