[Feature request]: Add watermark

[taimaiduc]

Can we backup original image then add watermark to an image?

[saqueib]

what type of watermark did you want to apply, Text or Image based?

I think we can add this feature with the following options:

 protected static $imageFields = [
        'poster' => [
            'width' => 800,
            'height' => 600,
            'watermark' => [
                'type' => 'text', // can be 'image' or 'text'
                'source' => 'Copyright QCod', // 'text' or 'image path'
                'position' => `bottom-right`,
                'offset' => [x, y]
            ]
        ]

what you think, any suggestion.

        'poster' => [
            'width' => 800,
            'height' => 600,
            'watermark' => [
                'type' => 'text', // can be 'image' or 'text'
               'style' => 'single or repeat'
                'source' => 'Copyright QCod', // 'text' or 'image path'
                'position' => `bottom-right`,
                'offset' => [x, y]
            ]
        ]

You should always keep original before add watermark or resize or crop I think it very important
Do you think so ?

We can add a command to remove all image and create another one when user change watermark source.

You know what I mean?

For example, we have an image with watermark is xxxxx but somehow we need to change xxxxx to ccccc

I think you should use manual resize for this feature.
Just disable the auto upload and resize the image however you want, you will have full Intervention Image instance access:

// disable the auto upload 
$model->setImagesField(['cover' => ['auto_upload' => false]);

// maually resize it
$originalImage = request()->file('orginalFile');
$resizedImage = $user->resizeImage($imageFile, [ 'width' => 800 ]);

// now watermark it 
// check this to implement it http://image.intervention.io/api/insert

I will add a generic watermark option in this package later. I am afraid your use case won't be covered completely with this, but here is what I will be adding:

protected static $imageFields = [
        'poster' => [
            'width' => 800,
            'height' => 600,
            'keep_original' => true, // keep the original with `original-` prefixed filename
            'watermark' => [
                'type' => 'text', // can be 'image' or 'text'
                'style' => 'single or repeat'
                'source' => 'Copyright QCod', // 'text' or 'image path'
                'position' => `bottom-right`,
                'offset' => [x, y]
            ]
        ]

How about adding a before_save and after_save options that will pass the intervention instance as a parameter and the developper can do whatever he wants with the image

protected static $imageFields = [
        'poster' => [
            'width' => 800,
            'height' => 600,
            'keep_original' => true, // keep the original with `original-` prefixed filename
            'before_save' =>function($image) {
                 // Do some stuff ...
            },
            'after_save' =>function($image) {
                 // Create the another image with the watermark
            },
        ]

I can make the PR for the callbacks

[saqueib]

@shadoWalker89 that will be great if you can pr this, give option to pass a closer or a class name with handle method on that class will get triggered

[shadoWalker89]

@saqueib PR is ready for inspection #8

[saqueib]

Closing #8 feature added with hooks
