Magnifying the Image

Mira provides a number of ways to magnify a displayed image. Here, magnifying the image refers to zooming the pixel display on the screen, not to changing the image scale on the pixel array, which involves resampling the pixel data (see, e.g., the Scale Image command).

In the table, below, the first two methods magnify the image about the point where you click the mouse. The last two methods magnify about the currently displayed center.
