Image SXM Help

Displays a dialog box with options for the style and positioning of a calibration bar. The size of the bar to be displayed is determined by the SEM magnification read from the parameter file and the selection of one of the three options in the dialog box. The colour of the bar is determined by the average shade of grey of the image area under the bar so that maximum contrast is obtained. If you want the opposite colour, just display the bar again. The font, size and style used for the bar label are set in the Options menu. In addition, the user has the option of selecting the optimum label size (a fixed proportion of the image size) in the dialog box. Press the option key to bypass the dialog box. Changes made to the image contrast and brightness settings will not affect the calibration bar. Note: If you want to do any image processing, such as executing the Smooth or Sharpen commands (in the Process menu), do so before displaying the calibration bar. This menu item is dimmed if the front window is not an SXM image window.
