      <doc xml:space="preserve">Implements a fragment shader using GLSL.

A fragment shader gets the coordinates being rendered as input and
produces the pixel values for that particular pixel. Additionally,
the shader can declare a set of other input arguments, called
uniforms (as they are uniform over all the calls to your shader in
each instance of use). A shader can also receive up to 4
textures that it can use as input when producing the pixel data.

`GskGLShader` is usually used with gtk_snapshot_push_gl_shader()
to produce a [class@Gsk.GLShaderNode] in the rendering hierarchy,
and then its input textures are constructed by rendering the child
nodes to textures before rendering the shader node itself. (You can
pass texture nodes as children if you want to directly use a texture
as input).

The actual shader code is GLSL code that gets combined with
some other code into the fragment shader. Since the exact
capabilities of the GPU driver differs between different OpenGL
drivers and hardware, GTK adds some defines that you can use
to ensure your GLSL code runs on as many drivers as it can.

If the OpenGL driver is GLES, then the shader language version
is set to 100, and GSK_GLES will be defined in the shader.

Otherwise, if the OpenGL driver does not support the 3.2 core profile,
then the shader will run with language version 110 for GL2 and 130 for GL3,
and GSK_LEGACY will be defined in the shader.

If the OpenGL driver supports the 3.2 code profile, it will be used,
the shader language version is set to 150, and GSK_GL3 will be defined
in the shader.

The main function the shader must implement is:

```glsl
 void mainImage(out vec4 fragColor,
                in vec2 fragCoord,
                in vec2 resolution,
                in vec2 uv)
```

Where the input @fragCoord is the coordinate of the pixel we're
currently rendering, relative to the boundary rectangle that was
specified in the `GskGLShaderNode`, and @resolution is the width and
height of that rectangle. This is in the typical GTK coordinate
system with the origin in the top left. @uv contains the u and v
coordinates that can be used to index a texture at the
corresponding point. These coordinates are in the [0..1]x[0..1]
region, with 0, 0 being in the lower left corder (which is typical
for OpenGL).

The output @fragColor should be a RGBA color (with
premultiplied alpha) that will be used as the output for the
specified pixel location. Note that this output will be
automatically clipped to the clip region of the glshader node.

In addition to the function arguments the shader can define
up to 4 uniforms for textures which must be called u_textureN
(i.e. u_texture1 to u_texture4) as well as any custom uniforms
you want of types int, uint, bool, float, vec2, vec3 or vec4.

All textures sources contain premultiplied alpha colors, but if some
there are outer sources of colors there is a gsk_premultiply() helper
to compute premultiplication when needed.

Note that GTK parses the uniform declarations, so each uniform has to
be on a line by itself with no other code, like so:

```glsl
uniform float u_time;
uniform vec3 u_color;
uniform sampler2D u_texture1;
uniform sampler2D u_texture2;
```

GTK uses the "gsk" namespace in the symbols it uses in the
shader, so your code should not use any symbols with the prefix gsk
or GSK. There are some helper functions declared that you can use:

```glsl
vec4 GskTexture(sampler2D sampler, vec2 texCoords);
```

This samples a texture (e.g. u_texture1) at the specified
coordinates, and contains some helper ifdefs to ensure that
it works on all OpenGL versions.

You can compile the shader yourself using [method@Gsk.GLShader.compile],
otherwise the GSK renderer will do it when it handling the glshader
node. If errors occurs, the returned @error will include the glsl
sources, so you can see what GSK was passing to the compiler. You
can also set GSK_DEBUG=shaders in the environment to see the sources
and other relevant information about all shaders that GSK is handling.

# An example shader

```glsl

If there is a problem, this function returns %FALSE and reports

Note that this will modify the rendering state (for example
change the current GL context) and requires the renderer to be
set up. This means that the widget has to be realized. Commonly you
want to call this from the realize signal of a widget, or during

The @args is a block of data to use for uniform input, as per types and

[method@Gsk.GLShader.format_args] or [struct@Gsk.ShaderArgsBuilder].

See [class@Gsk.GLShader] for details about how the shader should be written.

All the children will be rendered into textures (if they aren't already
`GskTextureNodes`, which will be used directly). These textures will be
sent as input to the shader.

If the renderer doesn't support GL shaders, or if there is any problem
when compiling the shader, then the node will draw pink. You should use
[method@Gsk.GLShader.compile] to ensure the @shader will work for the
renderer before using it.</doc>

Paths can used for rendering (filling or stroking) and for animations
(e.g. as trajectories).

`GskPath` is an immutable, opaque, reference-counted struct.
After creation, you cannot change the types it represents. Instead,
new `GskPath` objects have to be created. The [struct@Gsk.PathBuilder]
structure is meant to help in this endeavor.

Conceptually, a path consists of zero or more contours (continuous, connected
curves), each of which may or may not be closed. Contours are typically
constructed from Bézier segments.

The string is expected to be in (a superset of)
[SVG path syntax](https://www.w3.org/TR/SVG11/paths.html#PathData),
as e.g. produced by [method@Gsk.Path.to_string].

A high-level summary of the syntax:

- `M x y` Move to `(x, y)`
- `L x y` Add a line from the current point to `(x, y)`
- `Q x1 y1 x2 y2` Add a quadratic Bézier from the current point to `(x2, y2)`, with control point `(x1, y1)`
- `C x1 y1 x2 y2 x3 y3` Add a cubic Bézier from the current point to `(x3, y3)`, with control points `(x1, y1)` and `(x2, y2)`
- `Z` Close the contour by drawing a line back to the start point
- `H x` Add a horizontal line from the current point to the given x value
- `V y` Add a vertical line from the current point to the given y value
- `T x2 y2` Add a quadratic Bézier, using the reflection of the previous segments' control point as control point
- `S x2 y2 x3 y3` Add a cubic Bézier, using the reflection of the previous segments' second control point as first control point
- `A rx ry r l s x y` Add an elliptical arc from the current point to `(x, y)` with radii rx and ry. See the SVG documentation for how the other parameters influence the arc.
- `O x1 y1 x2 y2 w` Add a rational quadratic Bézier from the current point to `(x2, y2)` with control point `(x1, y1)` and weight `w`.

All the commands have lowercase variants that interpret coordinates
relative to the current point.

The `O` command is an extension that is not supported in SVG.</doc>

      <doc xml:space="preserve">Constructs `GskPath` objects.

A path is constructed like this:

```c
GskPath *
construct_path (void)
{
  GskPathBuilder *builder;

  builder = gsk_path_builder_new ();

  // add contours to the path here

  return gsk_path_builder_free_to_path (builder);
```

Adding contours to the path can be done in two ways.
The easiest option is to use the `gsk_path_builder_add_*` group
of functions that add predefined contours to the current path,
either common shapes like [method@Gsk.PathBuilder.add_circle]
or by adding from other paths like [method@Gsk.PathBuilder.add_path].

The `gsk_path_builder_add_*` methods always add complete contours,
and do not use or modify the current point.

The other option is to define each line and curve manually with
the `gsk_path_builder_*_to` group of functions. You start with
a call to [method@Gsk.PathBuilder.move_to] to set the starting point
and then use multiple calls to any of the drawing functions to
move the pen along the plane. Once you are done, you can call
[method@Gsk.PathBuilder.close] to close the path by connecting it
back with a line to the starting point.

This is similar to how paths are drawn in Cairo.

Note that `GskPathBuilder` will reduce the degree of added Bézier
curves as much as possible, to simplify rendering.</doc>

Optionally, returns the center of the osculating circle as well.
The curvature is the inverse of the radius of the osculating circle.

Lines have a curvature of zero (indicating an osculating circle of
infinite radius). In this case, the @center is not modified.

Circles with a radius of zero have `INFINITY` as curvature

Note that certain points on a path may not have a single curvature,
such as sharp turns. At such points, there are two curvatures — the
(limit of) the curvature of the path going into the point, and the
(limit of) the curvature of the path coming out of it. The @direction
argument lets you choose which one to get.

the result of a call to gsk_render_node_serialize() and
gsk_render_node_deserialize() will correctly reject files it cannot open
that were created with previous versions of GTK.

The intended use of this functions is testing, benchmarking and debugging.

      <doc xml:space="preserve">A facility to replay a [class@Gsk.RenderNode] and its children, potentially
modifying them.

This is a utility tool to walk a rendernode tree. The most powerful way
is to provide a function via [method@Gsk.RenderReplay.set_node_filter]
to filter each individual node and then run
[method@Gsk.RenderReplay.filter_node] on the nodes you want to filter.

If you want to just walk the node tree and extract information
without any modifications, you can also use [method@Gsk.RenderNode.get_children].

Here is a little example application that redacts text in a node file:

```
#include &lt;gtk/gtk.h&gt;

static GskRenderNode *
redact_nodes (GskRenderReplay *replay,
              GskRenderNode   *node,
              gpointer         user_data)
{
  GskRenderNode *result;

  if (gsk_render_node_get_node_type (node) == GSK_TEXT_NODE)
    {
      graphene_rect_t bounds;
      const GdkRGBA *color;

      gsk_render_node_get_bounds (node, &amp;bounds);
      color = gsk_text_node_get_color (node);

      result = gsk_color_node_new (color, &amp;bounds);
    }
  else
    {
      result = gsk_render_replay_default (replay, node);
    }

  return result;
}

int
main (int argc, char *argv[])
{
  GFile *file;
  GBytes *bytes;
  GskRenderNode *result, *node;
  GskRenderReplay *replay;

  gtk_init ();

  if (argc != 3)
    {
      g_print ("usage: %s INFILE OUTFILE\n", argv[0]);
      return 0;
    }

  file = g_file_new_for_commandline_arg (argv[1]);
  bytes = g_file_load_bytes (file, NULL, NULL, NULL);
  g_object_unref (file);
  if (bytes == NULL)
    return 1;

  node = gsk_render_node_deserialize (bytes, NULL, NULL);
  g_bytes_unref (bytes);
  if (node == NULL)
    return 1;

  replay = gsk_render_replay_new ();
  gsk_render_replay_set_node_filter (replay, redact_nodes, NULL, NULL);
  result = gsk_render_replay_filter_node (replay, node);
  gsk_render_replay_free (replay);

  if (!gsk_render_node_write_to_file (result, argv[2], NULL))
    return 1;

  gsk_render_node_unref (result);
  gsk_render_node_unref (node);

A dash pattern is specified by an array of alternating non-negative
values. Each value provides the length of alternate "on" and "off"
portions of the stroke.

Each "on" segment will have caps applied as if the segment were a
separate contour. In particular, it is valid to use an "on" length
of 0 with [enum@Gsk.LineCap.round] or [enum@Gsk.LineCap.square]
to draw dots or squares along a path.

If @n_dash is 0, if all elements in @dash are 0, or if there are
negative values in @dash, then dashing is disabled.

If @n_dash is 1, an alternating "on" and "off" pattern with the
single dash length provided is assumed.

If @n_dash is uneven, the dash array will be used with the first
element in @dash defining an "on" or "off" in alternating passes
through the array.

You can specify a starting offset into the dash with
[method@Gsk.Stroke.set_dash_offset].</doc>

The string is expected to be in (a superset of)
[SVG path syntax](https://www.w3.org/TR/SVG11/paths.html#PathData),
as e.g. produced by [method@Gsk.Path.to_string].

A high-level summary of the syntax:

- `M x y` Move to `(x, y)`
- `L x y` Add a line from the current point to `(x, y)`
- `Q x1 y1 x2 y2` Add a quadratic Bézier from the current point to `(x2, y2)`, with control point `(x1, y1)`
- `C x1 y1 x2 y2 x3 y3` Add a cubic Bézier from the current point to `(x3, y3)`, with control points `(x1, y1)` and `(x2, y2)`
- `Z` Close the contour by drawing a line back to the start point
- `H x` Add a horizontal line from the current point to the given x value
- `V y` Add a vertical line from the current point to the given y value
- `T x2 y2` Add a quadratic Bézier, using the reflection of the previous segments' control point as control point
- `S x2 y2 x3 y3` Add a cubic Bézier, using the reflection of the previous segments' second control point as first control point
- `A rx ry r l s x y` Add an elliptical arc from the current point to `(x, y)` with radii rx and ry. See the SVG documentation for how the other parameters influence the arc.
- `O x1 y1 x2 y2 w` Add a rational quadratic Bézier from the current point to `(x2, y2)` with control point `(x1, y1)` and weight `w`.

All the commands have lowercase variants that interpret coordinates
relative to the current point.

The `O` command is an extension that is not supported in SVG.</doc>
