What is PImage?
The PImage class contains fields for the width and height of the image, as well as an array called pixels that contains the values for every pixel in the image.
The methods described below allow easy access to the image’s pixels and alpha channel and simplify the process of compositing..
What is shrinking in image processing?
Shrinking, in the other hand involves reduction of pixels and it means lost of irrecoverable information. In this case scaling algorithm is to find the right pixels to throw away.
Why do we need to resize images?

Resizing means changing the size of the image, whatever the method: can be cropping, can be scaling. Scaling changes the size of the whole image by resampling it (taking, say every other pixel or duplicating the pixels*).
What is the difference between two options keep scale and keep image size while cropping an image?
When Keep scale is selected (default), cropping the image does not change the scale of the picture. When Keep image size is selected, cropping produces enlargement (for positive cropping values), shrinking (for negative cropping values), or distortion of the image so that the image size remains constant.
What is difference between stretching and resizing?
No part of the picture is removed or missed. Similarly, when you stretch an image to make it bigger, the pixels of the image is destroyed, and you see the picture blur — on the other hand, resizing increase the size of the picture by amending the pixels of the image.
What is the scaling?
Definition: Scaling is the procedure of measuring and assigning the objects to the numbers according to the specified rules. In other words, the process of locating the measured objects on the continuum, a continuous sequence of numbers to which the objects are assigned is called as scaling.
How do I resize an image in processing?
resize() Resize the image to a new width and height. To make the image scale proportionally, use 0 as the value for the wide or high parameter. For instance, to make the width of an image 150 pixels, and change the height using the same proportion, use resize(150, 0).
What do you mean by zooming an image?
When zooming, pixels are inserted into the image in order to expand the size of the image, and the major task is the interpolation of the new pixels form the surrounding original pixels. … A digital image is represented by an array of values, each value defining the color of a pixel of the image.
