1.3 Save LAS Image
The save function allows the user to save various XID windows to disk as
LAS format images. Any mappings currently applied to the image will be
applied to the image data before the image is written to disk and any
graphics data currently displayed is written into the image (i.e., engraved
into the image).
- LAS Image Name:
- Enter the name of the image to be created. This name may be entered
as a LAS name or a host name. No case conversions are done but keep
in mind that LAS does not handle names with upper-case letters properly.
The user is not required to press enter after entering the image
name since the name is not retrieved until the apply button is
pressed.
The save all, and save viewed radio buttons allow the user to
select what part of the image window will be saved.
- Save All:
- When selected, the entire image loaded into memory is saved to disk,
including any image data not currently visible. With this option,
only image and graphics data are saved (i.e., no window frames,
scrollbars, etc. are saved). The number of output bands created
for this option depends on the type of image displayed. If a black
and white image is displayed, all color channels are mapped the
same, and no graphics data is displayed, a single band image is
created, otherwise a 3-band image is created.
- Save Viewed:
- When selected, only the visible portion of the image is saved to
disk. The user is allowed to select the window to be saved
using the mouse much like the X application xwd. Technically,
this does not have to be an XID image window. It can be any window
currently visible on the display screen (eg., the root window,
a window from another application, the XID histogram window, etc.).
A 3-band image is always saved to disk using this option.
- Save Window:
- Select the XID image window to be saved. The user may choose from the
main image window, the full resolution image window, or the zoom image
window. This option is available only when the save all option
has been selected.
- Frame Option:
- Choose whether or not to save the window manager frame with the image.
If without frame is chosen and the window to be saved is an XID
image window (main image, full resolution or zoom window), the scroll bars
are not saved. This option is available only when the save
viewed option has been selected.
- Cancel:
- Close the save panel without saving an image to disk.
- Apply:
- Close the save panel, verify the validity of the image name entered in the
LAS Image Name field, and save the image data to disk according to
the specified options.
Note: The save viewed option does not work properly if a
mapping has been applied and the user is running the Open Windows
window manager.
