JBZoo / Image

Package provides object-oriented way to manipulate with images as simple as possible.

Install

composer require jbzoo/image

Example

use JBZoo\Image\Image;

$img = (new Image('./example/source-image.jpg'))
    ->addFilter('flip', 'x')
    ->addFilter('text', 'Some text', './res/font.ttf')
    ->thumbnail(320, 240)
    ->saveAs('./example/dist-image.png');

That block loads source-image.jpg, flip it horizontally, rotate it 90 degrees clockwise, shrink it to fit within a 320x240 box, apply a sepia effect, convert it to a PNG, and save it to dist-image.png with other format!

With this class, you can effortlessly:

Resize images (free resize, resize to width, resize to height, resize to fit)
Crop images
Flip/rotate/adjust orientation
Adjust brightness & contrast
Desaturate, colorize, pixelate, blur, etc.
Overlay one image onto another (watermarking)
Add text using a font of your choice
Convert between GIF, JPEG, PNG and WEBP formats
Strip EXIF data (Just save it!)

Usage

use JBZoo\Image\Image;
use JBZoo\Image\Filter;
use JBZoo\Image\Exception;

try { // Error handling

    $img = (new Image('./some-path/image.jpg'))     // You can load an image when you instantiate a new Image object
        ->loadFile('./some-path/another-path.jpg')  // Load another file (replace internal state)

        // Saving
        ->save()   // Images must be saved after you manipulate them. To save your changes to the original file.
        ->save(90) // Specify quality (0 to 100)

        // Save as new file
        ->saveAs('./some-path/new-image.jpg')     // Alternatively, you can specify a new filename
        ->saveAs('./some-path/new-image.jpg', 90) // You can specify quality as a second parameter in percents within range 0-100
        ->saveAs('./some-path/new-image.png')     // Or convert it into another format by extention (gif|jpeg|png|webp)

        // Resizing
        ->resize(320, 200)          // Resize the image to 320x200
        ->thumbnail(100, 75)        // Trim the image and resize to exactly 100x75 (crop CENTER if needed)
        ->thumbnail(100, 75, true)  // Trim the image and resize to exactly 100x75 (crop TOP if needed)
        ->fitToWidth(320)           // Shrink the image to the specified width while maintaining proportion (width)
        ->fitToHeight(200)          // Shrink the image to the specified height while maintaining proportion (height)
        ->bestFit(500, 500)         // Shrink the image proportionally to fit inside a 500x500 box
        ->crop(100, 100, 400, 400)  // Crop a portion of the image from left, top, right, bottom

        // Filters
        ->addFilter('sepia')                        // Sepia effect (simulated)

        ->addFilter('desaturate', 50)               // Desaturate
        ->addFilter('pixelate', 8)                  // Pixelate using 8px blocks

        // Other
        ->create(200, 100, '#000') // Create empty image 200x100 with black background
        ->setQuality(95)           // Set new internal quality state

    'text',                             // Filter name
    'Some image description',           // Text to render on image
    './resources/font.ttf'              // TTF font file
    [                                   // Additionals params
        'font-size'      => 48,                       // Font size in px
        'color'          => array('#ff7f00', '#f00'), // Or one color as string

        // Stroke
        'stroke-color'   => array('#f00', '#ff7f00'), // Or one color as string
        'stroke-size'    => 3,                        // Stroke size in px
        'stroke-spacing' => 5,                        // Letter spacing in px (only for stroke mode)

        // Position of text
        'offset-x'       => -140,       // X offset in px
        'offset-y'       => 100,        // Y offset in px
        'position'       => 't',        // top|t|Helper::TOP| ... More details in the method Helper::position()

        // Experimental
