When SAOimage is initiated, it will appear with the SAO logo which will be replaced by an image when one is displayed.
Menu items are chosen by clicking any mouse button (cf. Figure 5.1) on that item. There are several levels available, a level is entered and exited by clicking on the appropriate button. Click here for a brief description of the function of each menu item. A few, more complex, topics are described in more detail below.
Fine Movement
To move the mouse one pixel at a time, use the arrow keys on the keyboard.
Saving regions
To save/delete regions from the current buffer:
``s'' | save current cursor as an include region (counts within region will be included in subsequent calculations) |
``e'' | save current cursor as an exclude region (counts within region will be excluded from subsequent calculations) |
``d'' | delete most recent (or closest to mouse) region from save buffer |
To save regions in current buffer to a disk file select region,write.
Annuli
Annuli around a region are spaced either using the mouse directly (middle/right to add/delete respectively) or, if the mouse is positioned far from the region, equally spaced for each addition/deletion.
Blinking
Three blink buffers are available, one for each mouse button. An image is placed in the left/middle/right buffer by clicking the left/middle/right mouse button on the blink menu item. When another image is displayed, the earlier one can be compared with it by pressing its respective mouse button with cursor in the main display window. When the button is released, the current, loaded image will be re-displayed.
