This feature allows you to zoom in to a selected portion of the image.
Clilck on the "Zoom" button to bring up a new dialog box.
The drop box at the top of the box sets the amount of magnification. If Magnification=1.0 is set, the entire data set appears in the image; if Magnification=2.0 then only the center data pixels are shown, etc. If Magnification=0.5 the image is demagnified 50 percent. What we mean by "the center of the image" depends on how the centering buttons are set. If we select "Beam (Q=0) Center" then the center of the image will be the postion of the beam zero (or beamstop). If we select "Data Center" then the center of the image will be the true center of the data array. If we select "User Defined" then the user selects the position of the center. User selection of the center is done by clicking the "Enable Center Change" button, and dragging the blue dot that appears on the image or typing in the X and Y boxes. When all parameters are set to your satisfaction, click the Apply button. Examples:
