text_style

Charmy text style module.

This module is relatively simple, which only contains ability to express fonts.

class charmy.styles.text_style.WEIGHT

基类：object

Preset constant values of fontweight.

Introduction to TrueType Fontweight

TrueType fontweight determines the thickness of text. It has some common presets which are listed below. Learn more in [MSDN docs about this](https://learn.microsoft.com/en-us/dotnet/api/system.windows.fontweights?view=netframework-4.8#remarks).

List of Presets

THIN: int = 100

EXTRALIGHT: int = 200

LIGHT: int = 300

REGULAR: int = 400

MEDIUM: int = 500

SEMIBOLD: int = 600

class charmy.styles.text_style.TextStyle(font: _typing.Optional[str] = None, size: _typing.Optional[int] | float = None, weight: int = 400, italic: bool = False, underlined: bool | _draw.DrawnLine = False, strikethrough: bool | _draw.DrawnLine = False)

基类：object

Represents text styles in Charmy.

sys_fonts: _typing.ClassVar[list[str]] = ['Arial']

sys_default: _typing.ClassVar[_typing.Self] = <charmy.styles.text_style.TextStyle object>

__init__(font: _typing.Optional[str] = None, size: _typing.Optional[int] | float = None, weight: int = 400, italic: bool = False, underlined: bool | _draw.DrawnLine = False, strikethrough: bool | _draw.DrawnLine = False)

To express a font style in Charmy.

参数:

• font -- The name of the font to use, default is system font (reported by backend)

• size -- The size of the text, default is system font size (reported by backend)

• weight -- Weight of the text, in integer, default is charmy.font.WEIGHT.REGULAR which equals to 400

• italic -- Whether the text should be italic, default is False

• underlined -- Either a bool indicating if underlined, or a DrawnLine object to specify line used, default is False

• strikethrough -- Either a bool indicating if striked through, or a DrawnLine object to specify line used, default is False

For parameter weight

See [TrueType fontweight](https://learn.microsoft.com/en-us/dotnet/api/system.windows.fontweights?view=netframework-4.8#remarks) to learn more about the values. Presets are provided in charmy.font.WEIGHT class, which my be used in the way shown below

font: str

size: int | float

weight: int

italic: bool

underlined: bool | _draw.DrawnLine

strikethrough: bool | _draw.DrawnLine

static from_json(json_content)

get_text_boundary(text: str, backend: _typing.Optional[_backend.Backend]) → _shape.ShapeRange

Get boundary of a specific text in this style. (NOT IMPLEMENTED)
