Zooming (blowup) provides a more detailed view of a frame's features.
Use the Z command to toggle between zoomed and normal view states. Use the ZM command to set the zoom factor between 1 to 6. After setting the zoom factor, use the Z command to toggle to the zoomed state.
To roam in the zoomed state, press and hold the middle mouse button. Press the right mouse button to reposition the frame so the upper-left corner of the frame appears in the upper-left corner of the Image Window. If you specified the -autoResize flag at start up or in your .mcidasrc file, the Image Window is automatically resized to fit the zoomed frame.
