I have created custom attribute for featured product and fetched the product collection using object manager.

 <?php 
 $objectManager = MagentoFrameworkAppObjectManager::getInstance(); 
 $priceHelper = $objectManager->create('MagentoFrameworkPricingHelperData');

 $collection = $objectManager->create('MagentoCatalogModelResourceModelProductCollection')
 ->addAttributeToSelect('*')
 ->addAttributeToFilter('newest_product',['eq'=>1])
 ->addAttributeToFilter('status',MagentoCatalogModelProductAttributeSourceStatus::STATUS_ENABLED)
 ->load();

 foreach ($collection as $product) 
 
 $pdata = $product->getData(); 
 $store = $objectManager->get('MagentoStoreModelStoreManagerInterface')->getStore();
 $imageUrl = $store->getBaseUrl(MagentoFrameworkUrlInterface::URL_TYPE_MEDIA) . 'catalog/product' . $product->getImage();

 
 ?>

Here $imageUrl Returns the full image of the Product while I want the image of 300X400

I am trying to get the 300X400 size image in $imageurl code but not sure how to get the resized image. If you see the code, I have not used the helper method.

Need help to resize the product image to 300X400.

Any help would be appreciated.

Please check following steps for custom resize

Create a custom block

VendorModuleBlockImageresize;

in Imageresize.php

<?php
namespace VendorModuleBlock;

use MagentoStoreModelStoreManagerInterface;

class Imageresize extends MagentoFrameworkViewElementTemplate
 
 protected $_filesystem ;
 protected $_imageFactory;
 protected $_storeManager;
 protected $_objectManager;

 public function __construct( 
 MagentoFrameworkFilesystem $filesystem, 
 MagentoFrameworkObjectManagerInterface $objectManager,
 StoreManagerInterface $storeManager,
 MagentoFrameworkImageAdapterFactory $imageFactory 
 ) 
 $this->_filesystem = $filesystem; 
 $this->_imageFactory = $imageFactory; 
 $this->_objectManager = $objectManager;
 $this->_storeManager = $storeManager; 
 

 // pass imagename, width and height
 public function resize($image, $width = null, $height = null)
 
 $absolutePath = $this->_filesystem->getDirectoryRead(MagentoFrameworkAppFilesystemDirectoryList::ROOT)->getAbsolutePath('wordpress/wp-content/uploads/').$image;

 $imageResized = $this->_filesystem->getDirectoryRead(MagentoFrameworkAppFilesystemDirectoryList::MEDIA)->getAbsolutePath('resized/'.$width.'/').$image; 
 //create image factory...
 $imageResize = $this->_imageFactory->create(); 
 $imageResize->open($absolutePath);
 $imageResize->constrainOnly(TRUE); 
 $imageResize->keepTransparency(TRUE); 
 $imageResize->keepFrame(FALSE); 
 $imageResize->keepAspectRatio(TRUE); 
 $imageResize->resize($width,$height); 
 //destination folder 
 $destination = $imageResized; 
 //save image 
 $imageResize->save($destination); 

 $resizedURL = $this->_storeManager->getStore()->getBaseUrl(MagentoFrameworkUrlInterface::URL_TYPE_MEDIA).'resized/'.$width.'/'.$image;

 return $resizedURL;
 

?>

Now you can call your custom block function in anywhere in .phtml file.
using following code in your .phtml

$resizeBlock = $block->getLayout()->createBlock('VendorModuleBlockImageresize'); 
$imgResized = $resizeBlock->resize($image->getFile(),300,400);
