How can I remove the extra white background added to resized images from Magento. we have setup 700x700 image size for Product main image in view.xml. Image resize is working fine for the images higher thant 700x700 but when the images are smaller than 700x700  , it adds white background and does not look like the resize image. Instead it looks like it add white background as a canvas. How do i avoid this white canvas and have the smaller images resize to proper image size  ?

Thank You
