changing the image quality
Image quality can refer to the level of accuracy in which different imaging systems capture, process, store, compress, transmit and display the signals that form an image
Resizing an image
Image scaling — changing the size of a digital image while maintaining the proportions
Permission
Resolution is the number of pixels that light up on the screen horizontally and vertically.
Constrain Proportions
The Constrain Proportions option lets you maintain the aspect ratio (the ratio of image width to image height). If you select this option and change the image size and resolution, the image does not stretch or shrink
The Control Panel
The Control Panel is a component of Microsoft Windows that provides the ability to view and change system settings
image size
The Image Size consists of the width and height of an image. It can also be understood as the image resolution. Usually, these values are given in pixels and the following format: 1024x981.
Width
Then change width, height, or resolution. ... Note that for Width, the Columns option uses the width and gutter sizes specified in the Units & Rulers preferences.
inserting an image
You can easily insert an image into your current project as a new layer, which you can then resize, adjust, and even blend with other layers
Resampling an image
resampling your image is handled by the Image Size dialog box, which can be found under the Image menu
scale
scale is a ratio that shows how many times each line plotted on a map or drawing is smaller or larger than its actual dimensions.
