textAscent

以字体当前大小来计算当前字体的上升量。

上升代表最高字符的距离，以像素为单位，高于基线。

示例

let font;

function preload() {

font = loadFont('/assets/inconsolata.otf');

}

function setup() {

createCanvas(100, 100);

background(200);

// Style the text.

textFont(font);

// Different for each font.

let fontScale = 0.8;

let baseY = 75;

strokeWeight(0.5);

// Draw small text.

textSize(24);

text('dp', 0, baseY);

// Draw baseline and ascent.

let a = textAscent() * fontScale;

line(0, baseY, 23, baseY);

line(23, baseY - a, 23, baseY);

// Draw large text.

textSize(48);

text('dp', 45, baseY);

// Draw baseline and ascent.

a = textAscent() * fontScale;

line(45, baseY, 91, baseY);

数字: 以像素为单位测量的上升值。
