[Lazy-Image] Support for intervention/image v3

[Jibbarth]

Hi there !

While inspecting my dependencies, I just noticed that intervention/image had a new v3 version.

My project use ux-lazy-image. I was able to upgrade intervention/image to the last version, and few problems appears.

On LazyImageExtension, the instance of ImageManager need a driver now (Driver class or an instance of driver). Could be interesting to check if we have Imagick or GD available at this moment to pass with correct driver. However, if we need to support both v2 and v3, i think we should add more adjustment:

class LazyLoadExtension extends Extension implements PrependExtensionInterface
{
    public function load(array $configs, ContainerBuilder $container)
    {
        if (class_exists(ImageManager::class)) {
            $definition = new Definition(ImageManager::class);
            if (class_exists(\Imagick::class)) {
                $definition->addArgument(\Intervention\Image\Drivers\Imagick\Driver::class);
            } else if (class_exists(\GdImage::class)) {
                $definition->addArgument(\Intervention\Image\Drivers\Gd\Driver::class);
            }
            $container
                ->setDefinition('lazy_image.image_manager', $definition)
                ->setPublic(false)
            ;
        }
        // ...

Then, in the BlurHash service, there is few changes in the API provided by the imageManager.

I listed following :

• make() -> read()
• pixel() -> drawPixel() (and x,y in first args)
• canvas() -> create()
• pickColor return now a ColorInterface object, that can be converted in array with $color->toArray()
• getWidth() and getHeight() -> width() and height() on Image object

After made all this changes, I ended up with a "Unable to decode input" exception 🙈

Possible solutions

As a quickfix and to avoid the issue for new user that directly install the latest version of intervention/image, we can add a conflic to that v3.

If we don't want to support both version, we can work on the BlurHash service to migrate with the new API (https://image.intervention.io/v3/introduction/upgrade)

If we wan't keep support of that version, and to avoid lot of "method_exist" in the BlurHash service, we maybe should add a InterventionV3BlurHash service and inject it in BlurHash interface when we detect such a version (don't know if it's possible to guess version in the bundle extension by the way).

WDYT ?

I can handle modifications after your feedback.

What about a conflict with intervention V3 in this version, and then moving to https://github.com/bepsvpt/blurhash ?

The current lib used seems not very active, and if we can use a single (small) library instead of Blurhash + Intervention2/3 + "method_exist" code... WDYT ?

[Jibbarth]

Haha I forgot there was another lib between ux-lazy-image and intervention/image 😅

The only counterpart I see using the one you suggested is the dependency with illuminate/support that come with lot of dependency too.

The current lib was updated recently to explain how to use with latest version of intervention/image : kornrunner/php-blurhash@e3b9b36

Oh you're right... well if you feel to adapt the code for both Intervention2 & 3 that'd be ideal i guess

[Jibbarth]

Thanks for feedback. I'll give it a try 😉

There is another possibility i find appealing : https://github.com/SRWieZ/thumbhash/

Yes, saw it and I wondering if it was a good alternative. I should try it 😄
