Seadisp Roam Function: Program-level Documentation

Seadisp Roam Widget

Description: The Roam Widget provides a small sub-sampled view of the full resolution display image, which contains a view box corresponding to the viewable portion of the display window. You can easily move through the high-resolution display image by dragging the view box in the low-resolution roam window. The Roam Widget can be opened by selecting Functions->Roam On from the Display Window Widget. The Roam Widget can be turned off by selecting Functions->Roam Off or by killing the roam widget with the window manager.

Note: The view box in the roam widget should always reflect the viewable portion of the display window. Scrolling the display image with the scroll bars will cause the view box in the roam window to move to the new viewable display region.

Action items:

Left Mouse Drag Use the left mouse button to drag the box in the roam window to the area you wish to view in your full resolution display window. The display window will scroll to the selected region.

Middle Mouse Click Jump the view box to the cursor location and scroll the display window to this region.

Window Resize The roam window may be resized at any time to modify the default sub-sample factor (the initial size is 25% of full resolution image). Resize the roam window by dragging the corner of the window with the left mouse button. The resultant roam window will be the closest integer sub-sample rate that corresponds to the new window area specified.
