Figure 2 shows what the Process Button display looks like and what image processing features are currently available. With each Process Button display, there is an associated image display with the McIDAS image. Figure 3 is an example of an image display with a GOES-8 image. The most common method available is scaling the image by dividing the brightness values from the 10-bit image by 4. The user has four options to enhance the image features with a left or right bit shift operation on the 10-bit values.
Zeros fill the bit values vacated by the shift.
The user can shift the 10-bit values one bit or two bits in the left or right direction. High pass filters are available to emphasize high spatial features in the image and display as an 8-bit image. The DONE button removes the button display and it's matching image display from the workstation screen. Occasionally, the image selected by the user may have the x and y dimension larger than the workstation screen. Whenever, this happens, vertical and horizontal scroll bars appear on the image display.
