kennynguyeenx/image-service

Provide some functions to manipulate images

Features

• Resize image
• Set background color for image
• Create bigger image with old image in the center
• Convert image to the other type
• Dependencies: imagemagick, webp
• PSR-4 compatible.
• Compatible with PHP >= PHP 7.

Installation

• You can download image-service through https://github.com/kennynguyeenx/image-service.

• image-service requires the Multibyte String extension and the Imagick extension from PHP.

• Typically you can use the configure option --enable-mbstring while compiling PHP to have the Multibyte String extension. More information can be found in the PHP documentation.

• Imagick is a native php extension to create and modify images using the ImageMagick API. More information can be found in the PHP documentation.

Usage

• Resize image:

use Kennynguyeenx\ImageService\ImageService;

try {
    $imageService = new ImageService();
    $imageService->manipulateImage($imageUrl, $options, $outputImagePath, $outputFormat);
} catch (Exception $exception) {
    exit($exception->getMessage());
}

• $options should consist these keys: width (width of new image), height (height of new image), background (background color of new image if using canvas)

• I created a file to run in console to manipulate images as an example of using this class

• It's located at bin directory with name manipulate_image.php

• You can follow these steps to resize and convert image to the other type:

1. Save a image under the folder that you want. For me, i save it under images/source folder as example_image.png

2. This image have size is 300x300. We will try to resize it to 200x200 and convert it from png to gif. We can run this command:

$ php ./bin/manipulate_image.php ./images/source/example_image.png 200x200_ ./images/destination/updated_image.png gif

3. This is the result:
