Image Formats

The supported image formats depend on the used driver. While with Imagick and libvips it is possible to read all formats that the library itself supports and write the formats listed below with GD only the formats listed below are readable and writable.

Read more about encoding different image formats in the output section.

Please note that not all image formats are always included in the PHP image extensions. It is therefore possible, that the GD library is installed but is built without Jpeg support or Imagick is available without Webp support for example.

All these image formats can be read from various sources. These are in detail:

• Path in filesystem
• Raw binary image data
• Base64 encoded image data
• Data Uri Scheme
• File Pointer resource
• SplFileInfo from which Illuminate\Http\UploadedFile and Symfony\Component\HttpFoundation\File\UploadedFile are derived
• Intervention Image Instance (Intervention\Image\Image)
• Encoded Intervention Image (Intervention\Image\EncodedImage)
• Driver-specific image (instance of GDImage or Imagick)

Check the Support for Image Formats

public DriverInterface::supports(string|Format|FileExtension|MediaType $identifier): bool

This method can be used during runtime to find out whether a specific format is supported. It checks if the desired format is supported by the current driver and if the underlying extension has been built with the necessary support, returning true if both conditions are met.

Parameters

Example

use Intervention\Image\Drivers\Imagick\Driver as ImagickDriver
use Intervention\Image\Format;
use Intervention\Image\MediaType;
use Intervention\Image\FileExtension;

$manager = ImageManager::withDriver(ImagickDriver::class);

// check by file extension if driver supports jpeg format
$result = $manager->driver()->supports('jpg');

// check by media type if driver supports jpeg format
$result = $manager->driver()->supports('image/jpeg');

// check by enum member if driver supports jpeg format
$result = $manager->driver()->supports(Format::JPEG);

// check by enum member if driver supports jpeg format
$result = $manager->driver()->supports(MediaType::IMAGE_JPEG);

// check by enum member if driver supports jpeg format
$result = $manager->driver()->supports(FileExtension::JPG);

Color Formats

The library supports several formats to define colors for its methods.

The input values for colors may differ from the actual color space of the image. Therefore, it is possible to draw on a CMYK image using an HSV color specification. The colors will be automatically converted to the target color space.

String Format

Hexadecimal String Format

You can pass colors as RGB hex triplets, which are commonly used in HTML and CSS. It's possible to use the shorthand as well as the full format with or without an alpha channel. The leading # is optional.

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Imagick\Driver;

// create new image with red background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('b53717');

// create new image with half transparent red background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('b5371766');

RGB String Format

RGB string values in functional notation are also supported. To include an alpha value use the RGBA prefix, as shown in the following example.

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new image with half transparent background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('rgba(15, 20, 255, .5)');

// create new image with red background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('rgb(255, 0, 0)');

CMYK String Format

CMYK string values in functional notation are also supported.

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Imagick\Driver;

// create new image with background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('cmyk(100, 100, 55, 60)');

HSV/HSB String Format

It is also possible to pass color values strings in the RGB alternative HSV/HSB.

use Intervention\Image\ImageManager;

// create new image with half transparent background
$image = ImageManager::imagick()->read('example.jpg');

// draw colored pixel
$image->drawPixel(120, 200, 'hsv(230, 15, 75)');

HSL String Format

It is also possible to pass color values strings in the HSL color format.

use Intervention\Image\ImageManager;

// create new image with half transparent background
$image = ImageManager::imagick()->read('example.jpg');

// fill image with color
$image->fill(120, 200, 'hsl(100, 15, 10)');

HTML Color Names

Intervention Image can read colors from the extended 140 HTML color names from the W3C specification.

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;

// create new image with half transparent background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill('steelblue');

Transparency

If it is necessary to specify transparency as a color, this can always be done with the keyword transparent.

use Intervention\Image\ImageManager;

$manager = ImageManager::gd();
$image = $manager->read('images/example.png');
$image->pad(300, 200, 'transparent');

Color Objects

Colors can also be defined in object form. There is currently a separate color class for each color space.

RGB Color Object

The RGB color object uses three parameters for the basic channels as well as an optional alpha channel parameter, which is defined as completely opaque by default.

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Gd\Driver;
use Intervention\Image\Colors\Rgb\Color;

// create new image with half transparent background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill(new Color(45, 0, 10, .5));

// create new image with red background
$image = (new ImageManager(Driver::class))->create(300, 200)->fill(new Color(255, 0, 0));

CMYK Color Object

The CMYK color object is constructed using four parameters that correspond to the four channels of the color space.

use Intervention\Image\ImageManager;
use Intervention\Image\Colors\Cmyk\Color;

// create new image with half transparent background
$image = ImageManager::imagick()->create(300, 200)->fill(new Color(100, 100, 55, 60));

HSV/HSB Color Object

The HSV/HSB color object constructor takes three parameter for Hue, Saturation and Value/Brightness.

use Intervention\Image\ImageManager;
use Intervention\Image\Colors\Hsv\Color;

// create new image with half transparent background
$image = ImageManager::imagick()->create(300, 200)->fill(new Color(230, 15, 75));

HSL Color Object

The HSL color object constructor takes three parameter for Hue, Saturation and Luminance.

use Intervention\Image\ImageManager;
use Intervention\Image\Colors\Hsl\Color;

// create new image with half transparent background
$image = ImageManager::imagick()->create(300, 200)->fill(new Color(230, 15, 75));

Colorspaces

The available color spaces are primarily determined by the driver used. The Imagick driver supports both RGB and CMYK color spaces, whereas the GD driver only supports RGB. The default color space for newly created images is RGB.

Using the GD driver in Intervention Image to read CMYK images will automatically convert them to the RGB color space, which may result in color deviations.

Because the GD driver does not support CMYK, it is not recommended for use with CMYK images.

Read how to read an modify colorspace in the section about Meta Information.

Convert Colors to Other Colorspaces or Formats

Colors can always be converted to the supported color spaces. This is possible even if the driver does not support the desired color space.

Color objects can also be converted into the following formats.

• Intervention\Image\Colors\Rgb\Colorspace
• Intervention\Image\Colors\Cmyk\Colorspace
• Intervention\Image\Colors\Hsv\Colorspace
• Intervention\Image\Colors\Hsl\Colorspace

use Intervention\Image\ImageManager;
use Intervention\Image\Drivers\Imagick\Driver;
use Intervention\Image\Colors\Hsv\Colorspace as HsvColorspace;

// read RGB image from filesystem
$manager = new ImageManager(new Driver());
$image = $manager->read('example.jpg');

// retrieve color of pixel at given position
$color = $image->pickColor(100, 100);

// convert color to HSV format
$color = (string) $color->convertTo(HsvColorspace::class); // 'hsv(220, 10, 65)'
