Path class

This page explains the Path class.

What class is this?

The Path class creates a path vector graphics object.

Basic usage

The Path class constructor requires the path_data_list argument.

The path_data_list argument is a list of each path setting, such as the PathLineTo or PathBezier2D.

The constructor also accepts each style’s argument, such as the fill_color and line_color.

import apysc as ap

ap.Stage(
    background_color=ap.Color("#333"),
    stage_width=200,
    stage_height=100,
    stage_elem_id="stage",
)
path: ap.Path = ap.Path(
    path_data_list=[
        ap.PathMoveTo(x=50, y=50),
        ap.PathLineTo(x=150, y=50),
    ],
    line_color=ap.Color("0af"),
    line_thickness=5,
)

ap.save_overall_html(dest_dir_path="path_basic_usage/")

PathMoveTo class setting

The PathMoveTo class is the class to set a new position on a path.

For more information, please see:

PathLineTo class setting

The PathLineTo class is the class to set a new line from the current position on a path.

PathHorizontal class setting

The PathHorizontal class is the class to set a new horizontal line on a path.

For more information, please see:

PathVertical class setting

The PathVertical class is the class to set a new vertical line on a path.

For more information, please see:

PathClose class setting

The PathClose class is the class to close a path.

For more information, please see:

PathBezier2D class setting

The PathBezier2D class is the class to set a 2D bezier curve on a path.

For more information, please see:

PathBezier2DContinual class setting

The PathBezier2DContinual class is the class to set a continual 2D bezier curve on a path.

For more information, please see:

PathBezier3D class setting

The PathBezier3D class is the class to set a 3D bezier curve on a path.

For more information, please see:

PathBezier3DContinual class setting

The PathBezier3DContinual class is the class to set a continual 3D bezier curve on a path.

skew_y property interface example

The skew_y property updates or gets the instance’s skew-y (distortion) value:

import apysc as ap

ap.Stage(
    background_color=ap.Color("#333"),
    stage_width=150,
    stage_height=150,
    stage_elem_id="stage",
)
sprite: ap.Sprite = ap.Sprite()

path: ap.Path = ap.Path(
    path_data_list=[
        ap.PathMoveTo(x=50, y=50),
        ap.PathLineTo(x=50, y=100),
        ap.PathLineTo(x=100, y=100),
        ap.PathClose(),
    ],
    line_color=ap.Color("#0af"),
    line_thickness=3,
)


def on_timer(e: ap.TimerEvent, options: dict) -> None:
    """
    The timer event handler.

    Parameters
    ----------
    e : ap.TimerEvent
        Event instance.
    options : dict
        Optional arguments dictionary.
    """
    path.skew_y += 1


ap.Timer(handler=on_timer, delay=ap.FPS.FPS_60).start()
ap.save_overall_html(dest_dir_path="path_skew_y/")

[Interface summary]

Create a path vector graphic.

[Parameters]

  • path_data_list: list of PathDataBase

    • Target path data settings, such as the ap.PathData.MoveTo.

  • fill_color: Color, default COLORLESS

    • A fill-color to set.

  • fill_alpha: float or Number, default 1.0

    • A fill-alpha to set.

  • line_color: Color, default COLORLESS

    • A line-color to set.

  • line_alpha: float or Number, default 1.0

    • A line-alpha to set.

  • line_thickness: int or Int, default 1

    • A line-thickness (line-width) to set.

  • line_cap: String or LineCaps or None, default None

    • A line-cap setting to set.

  • line_joints: String or LineJoints or None, default None

    • A line-joints setting to set.

  • line_dot_setting: LineDotSetting or None, default None

    • A dot setting to set.

  • line_dash_setting: LineDashSetting or None, default None

    • A dash setting to set.

  • line_round_dot_setting: LineRoundDotSetting or None, default None

    • A round-dot setting to set.

  • line_dash_dot_setting: LineDashDotSetting or None, default None

    • A dash-dot (1-dot chain) setting to set.

  • parent: ChildMixIn or None, default None

    • A parent instance to add this instance. If the specified value is None, this interface uses a stage instance.

  • variable_name_suffix: str, default “”

    • A JavaScript variable name suffix string. This setting is sometimes useful for JavaScript debugging.

[Examples]

>>> import apysc as ap
>>> stage: ap.Stage = ap.Stage()
>>> path: ap.Path = ap.Path(
...     path_data_list=[
...         ap.PathMoveTo(x=0, y=50),
...         ap.PathBezier2D(control_x=50, control_y=0, dest_x=100, dest_y=50),
...     ],
...     line_color=ap.Color("#ffffff"),
...     line_thickness=3,
... )
>>> path.line_color
Color("#ffffff")

>>> path.line_thickness
Int(3)
