VGAlign¶

VGAlign is a small collection of constants that tell VGContext::textAlign where to anchor text relative to the coordinate you pass to text. You combine exactly one horizontal option with one vertical option using the bitwise OR operator (|).

namespace GL\VectorGraphics
{
    class VGAlign {}
}

Usage¶

use GL\VectorGraphics\VGAlign;

// anchor text at its left edge, vertically centered on the y coordinate
$vg->textAlign(VGAlign::LEFT | VGAlign::MIDDLE);
$vg->text(20, 100, "Hello world");
