Magento 2 Upload Svg Unsupported Image Format.

Why nosotros need to resize the image when we can overwrite original images?

When a developer works on custom modules having images, he/she would desire to fetch products or category images. They may face up problems with epitome beingness displayed in different sizes on the frontend. This situation can be resolved in ii ways: First is using CSS but this is not advisable. Second choice is resizing the actual paradigm and save it to the cache folder.

What are the benefits of resizing the actual epitome file instead of using CSS to resize them in HTML?

If at that place is a huge departure in the source and target prototype sizes, the default resizing utility offered by CSS cannot be used. One can resize the entire epitome or retain simply its primal function to accomplish the desired results.

How to resize the actual image in Magento 2?

In this web log, I am going to explain how to save resized image to a cache binder and every fourth dimension it returns the image when requested and information technology won't overwrite the original image.

For instance, you've added 400*300 sized image for a production category and you want that detail category to exist displayed on home folio with a size 256*180. It may not be a feasible solution to resize the original file each fourth dimension. Hence, designer would add the resized image that is 256*180 in the enshroud binder. Each fourth dimension when request is sent, it returns the prototype from cache. One can call information technology from whatever form, template, or block.

Step 1: Y'all need to create helper class file Image.php at VenderModuleHelperImage.php and the past below code.
[xml]< ?php
namespace VenderModuleHelper;
use MagentoFrameworkFilesystem;
use MagentoFrameworkUrl;
use MagentoFrameworkAppHelperAbstractHelper;
use MagentoFrameworkAppFilesystemDirectoryList;
form Prototype extends MagentoFrameworkAppHelperAbstractHelper {
protected $scopeConfig;
protected $storeManager;
protected $messageManager;
protected $_response;
protected $_resourceConfig;
protected $_responseFactory;
protected $_url;
protected $_filesystem;
protected $_directory;
protected $_imageFactory;
public part __construct(
MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig,
MagentoStoreModelStoreManagerInterface $storeManager,
MagentoFrameworkMessageManagerInterface $messageManager,
MagentoFrameworkAppResponseInterface $response,
MagentoFrameworkAppConfigStorageWriterInterface $resourceConfig,
MagentoFrameworkAppResponseFactory $responseFactory,
MagentoFrameworkUrlInterface $url,
MagentoFrameworkFilesystem $filesystem,
MagentoFrameworkImageAdapterFactory $imageFactory
)
{
$this->scopeConfig = $scopeConfig;
$this->_storeManager=$storeManager;
$this->messageManager=$messageManager;
$this->_response=$response;
$this->_resourceConfig=$resourceConfig;
$this->_responseFactory = $responseFactory;
$this->_url = $url;
$this->_filesystem = $filesystem;
$this->_directory = $filesystem->getDirectoryWrite(DirectoryList::MEDIA);
$this->_imageFactory = $imageFactory;
}
public function imageResize(
$src,
$width=35,
$peak=35,
$dir='resized/'
){
$absPath = $this->_filesystem
->getDirectoryRead(DirectoryList::MEDIA)
->getAbsolutePath().$src;
$imageResized = $this->_filesystem
->getDirectoryRead(DirectoryList::MEDIA)
->getAbsolutePath($dir).
$this->getNewDirectoryImage($src);
$imageResize = $this->_imageFactory->create();
$imageResize->open up($absPath);
$imageResize->backgroundColor([255, 255, 255]);
$imageResize->constrainOnly(TRUE);
$imageResize->keepTransparency(TRUE);
$imageResize->keepFrame(true);
$imageResize->keepAspectRatio(truthful);
$imageResize->resize($width,$height);
$dest = $imageResized ;
$imageResize->save($dest);
$resizedURL= $this->_storeManager->getStore()
->getBaseUrl(MagentoFrameworkUrlInterface::URL_TYPE_MEDIA).
$dir.$this->getNewDirectoryImage($src);
render $resizedURL;
}
public function getNewDirectoryImage($src){
$segments = array_reverse(explode('/',$src));
$first_dir = substr($segments[0],0,1);
$second_dir = substr($segments[0],1,ane);
return 'cache/'.$first_dir.'/'.$second_dir.'/'.$segments[0];
}
}
[/xml]
Footstep 2: Using below lawmaking you tin call in a higher place imageResize() method from any form, block or
[xml]$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$imgpath = $objectManager-&gt;create('VenderModuleHelperImage')-&gt;imageResize('IMAGE_PATH','50','l','YOUR_DIR_NAME/');[/xml]
Here you got the output every bit 50×50 Resize image. Now I am going to explain the methods I have used

1. getDirectoryRead() : While building your custom extension, you will usually need a path to your extension's files. However, sometimes you lot will need to get a root folder or maybe to media binder.

2. getAbsolutePath() : here you will be able to get the absolute path to salvage cache. We have to pass folder name in the parameter.

iii. backgroundColor(): used to set background color

4. constrainOnly():br ?–> constrainOnly(true): This volition not resize an image that is smaller than the dimensions inside the resize() part. The default value is true in Magento ii

constrainOnly(false): This volition resize an image that is smaller than the dimensions inside the resize() function

v. keepTransparency(): Past default it is Truthful, that means the epitome will non lose transparency.

6. keepFrame(): keepFrame(truthful): Properly remove white paradigm frame upon resizing photos in Magento

keepFrame(simulated): Properly doesn't remove white epitome frame upon resizing photos in Magento

7. keepAspectRatio(): keepAspectRatio(true): It maintains the ratio. if a graphic has an aspect ratio of 2:i, it means that the width is twice as large every bit the superlative. When resizing graphics, it is of import to maintain the attribute ratio

keepAspectRatio(false): It doesn't maintain the ratio.

Magento 2 – Properly remove white image from frame

[xml]< ?php foreach ($this->getGalleryImages() as $_image): ?>
<li>
<a href="#" onclick="popWin('<?php echo $this->getGalleryUrl($_image) ?>', 'gallery', 'width=300,height=300,left=0,tiptop=0,location=no,condition=aye,scrollbars=yep,resizable=yeah'); return false;" title="< ?php echo $this->htmlEscape($_image->getLabel()) ?>"><img class="lazyload" data-src="<?php echo $this-/><noscript><img class="lazyload" information-src="<?php echo $this-/><noscript><img src="<?php repeat $this-/></noscript></noscript>helper('itemize/epitome')->init($this->getProduct(), 'thumbnail', $_image->getFile())->keepFrame(false)->resize(56); ?>" alt="< ?php repeat $this->htmlEscape($_image->getLabel()) ?>" /></a>
</li>
< ?php endforeach; ?>[/xml]

Resize Product Images in Magento 2
Nosotros would hash out the ways in which you can resize the product images in Magento 2. You tin can use the following code:
[xml]<?php
/**
*
* @var MagentoCatalogModelProductRepository
*/
protected $_productRepository;

/**
*
* @var MagentoCatalogHelperImage
*/
protected $_productImageHelper;

/**
* @param MagentoBackendBlockTemplateContext $context
* @param MagentoCatalogModelProductRepository $productRepository
* @param MagentoCatalogHelperImage $productImageHelper
* @param array $data
*/
public function __construct(
MagentoBackendBlockTemplateContext $context,
MagentoCatalogModelProductRepository $productRepository,
MagentoCatalogHelperImage $productImageHelper,
assortment $data = []
)
{
$this->_productRepository = $productRepository;
$this->_productImageHelper = $productImageHelper;
parent::__construct($context, $data);
}

/**
* resize of the paradigm
* @see MagentoCatalogModelProductImage
* @param int $width
* @param int $height
* @return $this
*/
public office resizeImage($id, $image_type, $width, $height = null)
{
$product = $this->_productRepository->getById($id);
$resizedImage = $this->_productImageHelper->init($production, $image_type)
->constrainOnly(TRUE)
->keepAspectRatio(TRUE)
->keepTransparency(Truthful)
->keepFrame(False)
->resize($width, $height);
return $resizedImage;
}
[/xml]

In this case, $_productRepository is an object of MagentoCatalogModelProductRepository course and $_productImageHelper is an object of MagentoCatalogHelperImage class.

In the Office resizeImage, there are iv major parameters $id this is id of the product, $image_type that can "product_base_image" or "product_small_image","product_thumbnail_image" and $width, $summit is width and pinnacle of the image respectively.
