Question

Quizplus · Accepted Answer

When reducing the resolution of an image, it is the number of pixels that is decreased, not the size of the image itself. Therefore, no part of the image is cropped out. However, if the aspect ratio of the image is changed during the process, then parts of the image may appear "missing" due to the change in proportion.
