Full Scale/Low-High
The Full Scale/Low-High option buttons adjust how the range of data in the
image is displayed in the Frequency Distribution histogram and Transform
Plot. They do not change how the data is displayed in the image window.
Selecting Full Scale adjusts the Frequency Distribution and Transform Plot
displays so they show the full intensity range of the image.
Selecting From Low to High magnifies the range between the Low and High
sliders. This makes it easier to view your data if it does not occupy the full
intensity range of the image.
Log
The Log checkbox changes the way the data is displayed in the histogram so
you can better discern subtle changes in signal intensity.
Image Max/Min and Units
Image Max and Min display the range of signal intensity in the image.
The image units are determined by the type of scanner used to create the
image. For images measured in O.D.s, you can display the max and min O.D
values in the image by selecting the Calibrated Quantity checkbox. If this box
is unselected, the max and min numeric pixel values are displayed.
Invert Display
The Invert Display checkbox flips light bands on a dark background to dark
bands on a light background, and visa versa. Once, again, the actual data will
not change—only the image.
