Hello @jonny77,

The simplest way is to mask with an SVG. See libvips/libvips#2271

Thanks a lot , actually i have just png / jpg file . and i run vips in laravel . libvips/libvips#2271 is python

It's the same in php, eg.:

#!/usr/bin/env php
<?php

require __DIR__ . '/vendor/autoload.php';
use Jcupitt\Vips;

$image = Vips\Image::newFromFile($argv[1], ['access' => 'sequential']);
    
$cx = $image->width / 2;
$cy = $image->height / 2;
$r = min($cx, $cy);

$svg = <<<EOF
<svg viewBox="0 0 {$image->width} {$image->height}">
    <circle cx="{$cx}" cy="{$cy}" r="{$r}" fill="#000" />
</svg>
EOF;

$mask = Vips\Image::svgload_buffer($svg);

# svgload always makes RGBA ... we want the alpha
$alpha = $mask[3];

$image->bandjoin($alpha)->writeToFile($argv[2]);

Then using this test image:

I can run:

$ ./crop-svg.php ~/pics/240.jpg x.png

To make:

i tried so , and i got the right image what i want , though it not circle .
i want to generate a 300x300 transparent image , should i run this?

• @method static Image black(integer $width, integer $height, array $options = []) Make a black image.

but i do not know how to specify the options value , i checked the docs , but see nothing about the $option

Something like:

$black = Vips\Image::black(300, 300, [
    'bands' => 4
]);
