• A dropdown list of cameras to select from.
• The lens control, if this camera has a lens PV.
• The colormap control.  The user can select one of five colormaps: HSV, Hot, Jet, Cool, or Gray.  Each of these can be set up to be linear, log, or exponential, with user-specified minimum and maximum values.
• Averaging control.  The viewer can either display single frames, an on-IOC calculated average (if the IOC supports this), or a locally performed average.
• IOC image control (for camera type "IC" only, not displayed here).  If the IOC supports an on-IOC region of interest selection, controls to set the region and the bit-shift are displayed here.
• On-image markers.  The current location of the on-image markers are given here.  The buttons to the left of these location can be enabled so that left-clicking on the image will set the marker.

• Wiki Markup
  Region of interest control.  A region of interest can be selected in the viewer by either entering parameters or clicking on the "\[Set ROI\]" button and then left-clicking and dragging on the image.  Clicking on the "Reset ROI" button will set the region of interest to the entire image.

• Zoom control.   Controls are provided to zoom in, zoom out, zoom to the region of interest, or zoom to the actual image size.

3. Projections

Above and to the left of the main image are the projection areas.  The projection can either be an average over the ROI (shown in green), or a projection in the location of an on-image marker.  In the image above, both the ROI average and Marker 1 are enabled in the projection area.

A separate set of four markers is also provided in each projection window.

...

The projection controls are located in the upper-left corner of the window.  These include:

• The projection display control, which allows selection of any or all of the on-screen markers and the ROI average to be displayed in the projection areas.
• The projection range control.  If checked, this will automatically scale the projections between the minimum and maximum values. If unchecked, a constant scale from a minimum of 0 to a maximum of 1023 will be used.
• The on-projection marker control.  These display the current location of the four on-projection markers.  Clicking on one of the numbered buttons will allow the marker position to be set by clicking on the projection area.

5. Menus

The menus provide an alternate way of performing many of the control panel functions as well as a few other rarely-performed operations.
