Intervention Image supports several formats to define colors for its methods.
You can pass colors as a hex triplet used normally in HTML and CSS. It's possible to use six-digit format as well as the shorthand form. The leading # is optional.
// create new image with red background
$image = (new ImageManager('gd'))->create(300, 200, 'b53717');
Pass the RGB integers of a color as a PHP array with or without an alpha value.
// create new image with half transparent background
$image = (new ImageManager('gd'))->create(300, 200, [15, 20, 255, .5]);
RGB string values in functional notations are also supported. If you want to include an alpha value use the RGBA prefix like in the following example.
// create new image with half transparent background
$image = (new ImageManager('gd'))->create(300, 200, 'rgba(15, 20, 255, .5)');
A color is also recognized as an integer by all methods.
// create new image with background color
$image = (new ImageManager('gd'))->create(300, 200, 1829283);2023-09-08 更新
