- There is an IDL procedure called

- (which requires an IDL license), and also as a pre-built IDL .sav file that can
- be run for free under the IDL Virtual Machine. This IDL program can run on any machine
- that IDL runs on, and that has the ezcaIDL shareable library built for it. This

- The control window for epics_ad_display is shown below. It has a field
- to input the base name of the EPICS PVs with the image data. It also has fields
- to enable/display the IDL display update, to change the display mode, to autoscale
- the intensity, and to invert the image in the Y direction. If autoscale is set to
- No then manual scaling can be entered in the Min and Max fields. The number of frames
- per second actually being displayed by IDL is shown. There is a status window that
