Main difference: Zooming allows the user to change the view of a document or image. There are two ways: zoom in and zoom out. Typically, pixels are shrunk or stretched. Pan is a different view of the view you want. This is achieved by grabbing the document and then sliding it to focus on the desired area or target area. Scaling changes the image or text. There are numerous techniques that are used to scale. Sometimes scaling and zooming are used interchangeably.

Zooming, panning, and scaling are related because all three are used in the context of a particular view on the screen. Zooming allows the user to change the view of a document or image. There are two ways: zoom in and zoom out.

You can zoom in to see the area on the screen more closely. On the other hand, zooming out allows for a larger view. The zoom function is often accompanied by scroll bars that appear when the screen is not wide enough to accommodate the entire contents of the page. It is generally represented by a magnifying glass icon. A + sign shows enlarged, while - sign is reduced. In modern browsers, zooming is only achieved by stretching the pixels. In general, the techniques are used in which pixels stretch in both width and height directions.

Pan is a different view of the view you want. This is achieved by grabbing the document and then sliding it to focus on the desired area or target area. It allows access to areas that might otherwise remain hidden from the user.

Dragging allows you to quickly move around the area at the same user-set magnification. It is usually represented by a symbol that shows a hand.

Scaling is a process that helps a user display specific text or a specific image. Scaling changes the image or text. There are numerous techniques that are used to scale. For example, in a scaling method for the interpolation of the nearest neighbors, each pixel is simply replaced by four pixels of the same size. Scaling is also used to enlarge or reduce digital images.

When zooming, all areas of the display image or text are uniformly influenced. However, when scaling, an encoder can use similar techniques - resizing can be done by keeping the original height and changing the width, or just the other way around. An image (or areas of an image) can be enlarged using pixel replication or interpolation.

Scaling is used in conjunction with increasing the physical size of the elements. As opposed to just stretching the pixels, techniques such as nearest neighbor interpolation are used to resize them. It's important to note that the term scaling is also used to refer to the resizing of the image that appears on the paper it needs to be printed on, without any kind of pixel resampling. It just stretches the image on the paper and doesn't change or alter the actual pixels.

Common method

Stretch the pixels

With the hand tool

Using techniques such as nearest neighbor interpolation to resize

In other contexts

Only the focus of the camera is shifted further or closer to the object. No change in the length, width and depth of the object

- A photographic technique for capturing a moving object

Changes the width, length, and depth of the object to make it smaller or larger
