Which method is used to keep the proportions of width and height the same when resizing an image?

The method used to maintain the proportions of width and height when resizing an image is known as "Constrain Proportions." This technique ensures that any adjustments made to the size of the image will keep the original aspect ratio intact, preventing distortion. This is particularly important in multimedia work, as stretching an image disproportionately can lead to a visually unappealing result that alters its intended appearance.

By constraining proportions during resizing, you ensure that the image retains its intended composition and looks natural. This is essential when working with photographs, graphics, or any visual content where maintaining the integrity of the image is crucial for professional-quality output. Other methods, such as cropping or stretching the image, do not preserve the aspect ratio and can lead to unwanted visual artifacts.
