The mousezoom is an application that uses a strong megafaring glass to show an up to 2x to 50x anodized zoom and you can increase the area you want.
It does not affect the registry and takes only 30 kb space. However, this is a powerful tool that allows you to open an image area to see it in more detail.
Zoom is applied only to areas where you place the mouse cursor, and it will display both its location and its full position with color code.
For example, this tool can tell you about any color shade RGB, as well as expand the image which you want to see more closely
