modeling/text

文本为每个字符或字符串提供线段集合。这些线段可用于为二维和三维几何图形创建轮廓。注意：仅支持 ASCII 字符。

Example

const { vectorChar, vectorText } = require('@jscad/modeling').text

• modeling/text
  • .vectorChar([options], [char])
  • .vectorText([options], [text])

modeling/text.vectorChar([options], [char])

从ASCII 字符（编码范围 31 至 127） 构造一个 VectorCharObject（矢量字符对象）；若该字符不被支持，则会替换为问号。

Kind: static method of modeling/text

Param	Type	Default	Description
[options]	Object | String		options for construction or ascii character
[options.xOffset]	Float	0	x offset
[options.yOffset]	Float	0	y offset
[options.height]	Float	21	font size (uppercase height)
[options.extrudeOffset]	Float	0	width of the extrusion that will be applied (manually) after the creation of the character
[options.input]	String	'?'	ascii character (ignored/overwrited if provided as seconds parameter)
[char]	String	'?'	ascii character

Example

let vectorCharObject = vectorChar()
let vectorCharObject = vectorChar('A')
let vectorCharObject = vectorChar({ xOffset: 57 }, 'C')
let vectorCharObject = vectorChar({ xOffset: 78, input: '!' })

modeling/text.vectorText([options], [text])

Construct an array of character segments from a ascii string whose characters code is between 31 and 127, if one character is not supported it is replaced by a question mark.

Kind: static method of modeling/text
Returns: Array - characters segments [[[x, y], ...], ...]

Param	Type	Default	Description
[options]	Object | String		options for construction or ascii string
[options.xOffset]	Float	0	x offset
[options.yOffset]	Float	0	y offset
[options.height]	Float	21	font size (uppercase height)
[options.lineSpacing]	Float	1.4	line spacing expressed as a percentage of font size
[options.letterSpacing]	Float	1	extra letter spacing expressed as a percentage of font size
[options.align]	String	'left'	multi-line text alignment: left, center, right
[options.extrudeOffset]	Float	0	width of the extrusion that will be applied (manually) after the creation of the character
[options.input]	String	'?'	ascii string (ignored/overwrited if provided as seconds parameter)
[text]	String	'?'	ascii string

Example

let textSegments = vectorText()
let textSegments = vectorText('OpenJSCAD')
let textSegments = vectorText({ yOffset: -50 }, 'OpenJSCAD')
let textSegments = vectorText({ yOffset: -80, input: 'OpenJSCAD' })

VectorCharObject

Represents a character as a list of segments

Kind: global typedef
Properties

Name	Type	Description
