Text embedding¶

GImage supports text embedding with custom TTF fonts using Text class and Canvas.

Tip

Use setAlign(str), setValign(str) functions for control the aligment, setLineHeight(n) for line spaces or setLeft(x) and setTop(y) for position on canvas.

<?php

use GImage\Text;
use GImage\Figure;
use GImage\Canvas;

// figure layout used as canvas
$figure = new Figure(400, 250);
$figure
    ->setBackgroundColor(47, 42, 39)
    ->create();

// text definition
$text = new Text('My Text with opacity!');
$text
    // box area size for text
    ->setWidth(400)
    ->setHeight(250)
    // aligments
    ->setAlign('center') // "none" by default
    ->setValign('center') // "none" by default
    // line height
    ->setLineHeight(1.2)
    // font size
    ->setSize(22)
    // font color
    ->setColor(255, 255, 255)
    // font face
    ->setFontface('/my/path/fonts/Lato.ttf');

    ->setOpacity(0.5)

// canvas definition
$canvas = new Canvas($figure);
$canvas
    // append the text element
    ->append($text)
    ->toPNG()
    ->draw()
    ->save('text.png');
