Add pathops.
2023-07-25 08:23:52 +03:00
Matthias Clasen ef122df3e3 gtk-demo: Add a demo for path ops
This demo is called Glyphs, since that is what
it works with.
2023-07-25 08:23:52 +03:00
Matthias Clasen ce72ad2e1d build: Bump the harfbuzz requirement to 4.0
The hb_font_get_glyph_shape api was introduced
in 4.0.
2023-07-25 08:23:52 +03:00
Matthias Clasen b2c0aa18be Add API for boolean operations on paths
The new APIs here are:
gsk_path_union
gsk_path_intersection
gsk_path_difference
gsk_path_symmetric_difference
gsk_path_simplify
2023-07-25 08:23:52 +03:00
Matthias Clasen beca8b4a39 Implement boolean operations on paths
Implement union, intersection, difference and
symmetric difference of two paths, as well as
simplification of a single path.
2023-07-25 08:23:52 +03:00
Matthias Clasen c3275e99a5 gsk: Add gsk_stroke_node_get_stroke_path
We will implement stroking by filling the stroke path.

Compute the stroke path ahead of time, so we don't have
to do it over and over.

This may change in the future, at least for simple
strokes, so keep this private.
2023-07-25 08:23:52 +03:00
Matthias Clasen 09f8f34583 gtk-demo: Add a curve editor demo
This demo is called Curve, for obvious reasons.
2023-07-25 08:23:52 +03:00
Matthias Clasen 776cc6a9ee gtk-demo: Add a few path benchmarks
The Tiger and Graph examples in the fishbowl test
path handling.
2023-07-25 08:23:52 +03:00
Matthias Clasen 49c38ca8d9 Add a gallery of tough strokes
Each of these defeated the stroker at some point.
2023-07-25 08:23:52 +03:00
Matthias Clasen 910d03c9de Add an interactive path test
This one is for interactive exploring of svg paths.

You can enter an SVG path in the entry and hit Enter
to see how GSK renders it. If you click the button
in the headerbar, you can see what GTK thinks the
closest point, tangent and distance are wrt. to the
mouse position, and the bounding box of the path.

There's also stroke parameters to play with.
2023-07-25 08:23:52 +03:00
Matthias Clasen c1a86c9911 tools: Add more commands to gtk4-path-tool
Add stroking and offsetting.
2023-07-25 08:23:52 +03:00
Matthias Clasen c460a1a002 Add gsk_path_stroke
Implement stroking for paths.

The current implementation does not try to handle short
segments in the vicinity of sharp joins in any special
way, so there can be some artifacts in that situation.

There are special-case implementations for rectangle
and circle contours, since in many cases the outlines
of these contours just consist of two of the same
shapes.
2023-07-25 08:23:52 +03:00
Matthias Clasen c1fd77ed45 Add more curve tests
These tests check that gsk_curve_intersect finds
the intersections we want and get_bounds returns
proper bounding boxes.

We also check a few simple cases of offset curves.
2023-07-25 08:23:52 +03:00
Matthias Clasen 42f67d6138 curve: Add gsk_curve_offset
This method creates an offset curve from an existing
curve by just moving the control points laterally.

This will be used in stroking.
2023-07-25 08:23:52 +03:00
Matthias Clasen 3f6074f250 curve: Add gsk_curve_intersect
Add a way to find the intersections of two curves.
We can handle some curve-line intersections directly,
the general case is handled via bisecting.

This will be used in stroking and path ops.
2023-07-25 08:23:52 +03:00
Matthias Clasen e350b1761a curve: Add utilities for cusps and inflections
Add functions to find cusps and inflection points of cubics.
These will be used for intersections and in the stroker.
2023-07-25 08:23:52 +03:00
Matthias Clasen 37d8677041 tools: Add gtk4-path-tool
This comes in handy for testing, among other things.

For now, this supports decomposing,
reversing, restricting, rendering and preview.
2023-07-25 08:23:52 +03:00
Benjamin Otte 1d4508a2a0 demos: Add cute maze demo 2023-07-25 08:23:52 +03:00

Benjamin Otte 50ec9b849e WIP: css: Replace border rendering code with GskPath
The weight is wrong still, I need to compute the correct one to get real
45deg circle corners and not just roughly correct ones.
2023-07-25 08:23:52 +03:00
Matthias Clasen e619ef4b81 gsk: Add tests for gsk_path_dash 2023-07-25 08:23:52 +03:00
Matthias Clasen 4e976cdd1d Add gsk_path_dash
This is a function like gsk_path_foreach, but
it provides a dashed version of the path instead
of the original.
2023-07-25 08:23:52 +03:00
Benjamin Otte a8bd3fdb28 snapshot: Add gtk_snapshot_push_stroke()
This is the obvious GtkSnapshot API to go
along with the new stroke nodes.
2023-07-25 08:23:52 +03:00
Benjamin Otte 9f981adf67 gsk: Add GskStrokeNode
Take a rendernode as source and a GskPath and GskStroke,
and fill the area that is covered when stroking the path
with the given stroke parameters, like cairo_stroke() would.
2023-07-25 08:23:52 +03:00
Matthias Clasen e337dd9448 Add gsk_path_get_stroke_bounds
This is a help to compute the bounds for
stroke nodes. We keep it private for now.
2023-07-25 08:23:52 +03:00
Matthias Clasen 351654bd27 Add GskStroke
A GskStroke struct collects the parameters that are
needed for stroking a path.
2023-07-25 08:23:52 +03:00
Matthias Clasen dbf8566538 Add another curve decomposition test
This one uses GskPathMeasure to check that
our conic approximations look roughly right.
2023-07-25 08:23:52 +03:00
Matthias Clasen 98d77c04d3 Add tests for GskPathMeasure 2023-07-25 08:23:52 +03:00
Matthias Clasen bfacbc72a0 Add GskPathMeasure
GskPathMeasure is an auxiliary object for
measuring path lengths.
2023-07-25 08:23:51 +03:00
Benjamin Otte 439f36be9f gtk: Add gtk_snapshot_push_fill()
This is the obvious GtkSnapshot API to go
along with the new fill nodes.
2023-07-25 08:23:51 +03:00
Benjamin Otte ff2007424c gsk: Add GskFillNode
Take a rendernode as source and a GskPath and fill
the region in the path just like cairo_fill() would.
2023-07-25 08:23:51 +03:00
Matthias Clasen fa47f63875 gsk: Add tests for GskPath 2023-07-25 08:23:51 +03:00
Matthias Clasen 3c7f4a141a gsk: Add tests for GskCurve 2023-07-25 08:23:51 +03:00
Matthias Clasen 90e50b35ee gsk: Add basic path infrastructure
This commit adds GskPath, GskPathPoint and GskPathBuilder.

GskPath is a data structure for paths that consists
of contours, which in turn might contain Bézier curves.

The data structure is inspired by Skia, with separate
arrays for points and operations. One advantage of this
arrangement is that start and end points are shared
between adjacent curves.

In addition to the usual contours comprised of Bézier
segments, GskPath supports certain special contours
directly, such as rectangles, rounded rectangles and
circles.
2023-07-25 08:23:51 +03:00
Matthias Clasen 14e3ab9672 Add a bounding box type
graphene_rect_t does not quite work for this purpose.

=========================================
* List widgets:
- Add scroll_to APIs
* GtkFileLauncher:
- Add an always-ask property
* GtkTextView:
- Make backspace behavior match GtkEntry
* gsk:
- Fix handling of luminance in mask nodes

- Fix behavior of stylus buttons
- Support suspended window state
* Vulkan:
- Many improvements
* Tools:
- Add gtk4-rendernode-tool
* Debugging:
- Drop the GTK_DEBUG_TOUCHSCREEN flag

Once you have all the necessary dependencies, you can build GTK by using
Meson:
```sh
$ meson setup _build
$ meson compile -C_build
$ meson _build .
$ cd _build
$ ninja
```
You can run the test suite using:
```sh
$ meson test -C_build
$ meson test
```
And, finally, you can install GTK using:
```
$ sudo meson install -C_build
$ sudo ninja install
```

DESCRIPTION
-----------
``gtk4-path-tool`` can perform various tasks on paths. Paths are specified
in SVG syntax, as strings like "M 100 100 C 100 200 200 200 200 100 Z".
To read a path from a file, use a filename that starts with a '.' or a '/'.
To read a path from stdin, use '-'.
COMMANDS
--------
Stroking
^^^^^^^^
The ``stroke`` command performs a stroke operation along the path according to
the parameters specified via options.
``--line-width=VALUE``
The line width to use for the stroke. ``VALUE`` must be a positive number.
The default line width is 1.
``--line-cap=VALUE``
The cap style to use at line ends. The possible values are ``butt``, ``round``
or ``square``. See the SVG specification for details on these styles.
The default cap style is ``butt``.
``--line-join=VALUE``
The join style to use at line joins. The possible values are ``miter``,
``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
for details on these styles.
The default join style is ``miter``.
``--miter-limit=VALUE``
The limit at which to clip miters at line joins. The default value is 4.
``--dashes=VALUE``
The dash pattern to use for this stroke. A dash pattern is specified by
a comma-separated list of alternating non-negative numbers. Each number
provides the length of alternate "on" and "off" portions of the stroke.
If the dash pattern is empty, dashing is disabled, which is the default.
See the SVG specification for details on dashing.
``--dash-offset=VALUE``
The offset into the dash pattern where dashing should begin.
The default value is 0.
Offsetting
^^^^^^^^^^
The ``offset`` command applies a lateral offset to the path. Note that this
is different from applying a translation transformation.
``--distance=VALUE``
The distance by which to offset the path. Positive values offset to the right,
negative values to the left (wrt to the direction of the path). The default
value is 0.
``--line-join=VALUE``
The join style to use at line joins. The possible values are ``miter``,
``miter-clip``, ``round``, ``bevel`` or ``arcs``. See the SVG specification
for details on these styles.
The default join style is ``miter``.
``--miter-limit=VALUE``
The limit at which to clip miters at line joins. The default value is 4.
Boolean Operations
^^^^^^^^^^^^^^^^^^
The ``intersection``, ``union``, ``difference`` and ``symmetric-difference`` commands
perform boolean operations on paths. Given two paths, they create a new path which
encircles the area that is the intersection, union, difference or symmetric difference
of the areas encircled by the paths.
Simplification
^^^^^^^^^^^^^^
The ``simplify`` command removes areas of overlap from a path such that the resulting
path encircles the same area, but every edge in the resulting path is a boundary between
the inside and the outside.
Decomposing
^^^^^^^^^^^
The ``decompose`` command approximates the path by one with simpler elements.
When used without options, the curves of the path are approximated by line
segments.
``--allow-curves``
Allow cubic Bézier curves to be used in the generated path.
``--allow-conics``
Allow rational quadratic Bézier curves to be used in the generated path.
Restricting
^^^^^^^^^^^
The ``restrict`` command creates a path that traces a segment of the original
path. Note that the start and the end of the segment are specified as
path length from the beginning of the path.
``--start=LENGTH``
The distance from the beginning of the path where the segment begins. The
default values is 0.
``--end=LENGTH``
The distance from the beginning of the path where the segment ends. The
default value is the length of path.
Showing
^^^^^^^
The ``show`` command displays the given path in a window. The interior
of the path is filled.
``--fill-rule=VALUE``
The fill rule that is used to determine what areas are inside the path.
The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
``--fg-color=COLOR``
The color that is used to fill the interior of the path.
If not specified, black is used.
``--bg-color=COLOR``
The color that is used to render the background behind the path.
If not specified, white is used.
Rendering
^^^^^^^^^
The ``render`` command renders the given path as a PNG image.
The interior of the path is filled.
``--fill-rule=VALUE``
The fill rule that is used to determine what areas are inside the path.
The possible values are ``winding`` or ``even-odd``. The default is ``winding``.
``--fg-color=COLOR``
The color that is used to fill the interior of the path.
If not specified, black is used.
``--bg-color=COLOR``
The color that is used to render the background behind the path.
If not specified, white is used.
``--output-file=FILE``
The file to save the PNG image to.
If not specified, "path.png" is used.
Info
^^^^
The ``info`` command shows various information about the given path,
such as the number of contours, its bounding box and and its length.
