Zoom in and out images by mouse wheel
In the detail mode, Eagle provides many ways to resize images such as shortcuts and dropdown list. These functions are very convenient for us to quickly view an image in a specific size such as 50,% 100%, 150%.
Sometimes we don't need to view an image in a fixed ratio. Instead, we zoom in on a point on the image. For such a use scene, Eagle provides the "Focus Zoom In" function to let you zoom in the point of the image.
Focus Zoom In
After you open the image, moving the mouse to the point you want to view, pressing the "Alt" button and scrolling the mouse wheel, you can view the zoom in to the point.
