Magento – how to change or off in backend for uploading image default MAX WIDTH

image-uploadmagento2

In Backend -> PRODUCTS -> CATALOG -> [any product] -> Images and Videos when uploading images, Magento automatically makes resize(max-width 1920px). I need a image width 2600px. each product with self background. I created the Image-attribute: produkt_bg and show it on the product page. but the width is not enough.

How do I change this or turn it off in backend for uploading image default MAX WIDTH?

After a lot of digging in the code, I found that M2 resize the image on the client, that's it, before even uploading to the server. This will be true if you use a browser that support Canvas and the File API.

To prevent this, you have to remove:

// vendor/magento/module-backend/view/adminhtml/web/js/media-uploader.js:113
{
     action: 'resize',
     maxWidth: this.options.maxWidth,
     maxHeight: this.options.maxHeight
},

To be honest, I don't know exactly how to remove it in a clean way. The "easy way" would be remapping Magento_Backend/js/media-uploader to a custom js file and brutally copy/paste.

By the way, the above file is called here:
vendor/magento/module-backend/view/adminhtml/templates/media/uploader.phtml

It sounds like you are trying to write your media to another server rather than just serve them from a different domain. This isn't possible through configuration in magento. Even if you could you would need the media on the magento server as magento checks on its local filesystem to see if a file exists before serving it to the browser, you would end up with a page of placeholder images.

What you could do to achieve what you are after is use an external disk which is shared via nfs and mounted on both your magento and media servers. That way your media is written locally from magento but available on your second server through the shared drive.

That said, I'm not sure your requirements but a CDN solution may be a better option for you.

Either set keepFrame to true, so it's always exact 160x210, or set keepAspectRatio to false.

Now it is making sure both width and height won't exceed the values you feed it. But since you don't want a frame, and want to keep your aspect ratio, it has to change both width and height in the same ratio.

<?php 
echo $this->helper('catalog/image')->init($_product, 'small_image')
    ->constrainOnly(false)
    ->keepAspectRatio(true)
    ->keepFrame(true)
    ->resize(160, 210);
?>

Edit: For cropping you need to use Varien_Image. Unfortunately the Mage_Catalog_Helper_Image doesn't offer a method to return the Varien_Image class. So you need to make a custom module to make it possible to crop.

See https://stackoverflow.com/questions/9492770/magento-crop-image for an example.

Basically it says you need to make your own helper and extend Mage_Catalog_Helper_Image, so you can use $this->_getModel()->getImageProcessor()->crop()
