What is difference between zooming and scaling?
Image zooming is achieved by pixel replication or by interpolation. Scaling is used to change the visual appearance of an image, to alter the quantity of information stored in a scene representation, or as a low-level preprocessor in multi-stage image processing chain which operates on features of a particular scale.
How do you zoom in on a point using scale and translate?
If you have an image and scale it by a factor of 2, the bottom-right point will double in both x and y direction as (0, 0) is the top-left of the image. If you like to zoom the image of the center then a solution is as follows: Translate the image. Scale the image by x and y factors.
