If the file that you are loading contains multiple records, enter the starting number of the record
that you want to begin loading from, in the edit box labeled Start Record.
Enter the Number of Records that you want to Load. You can enter a value of 0, or 1 to the
number of records in the file. A value of 0 means all the records in the file.
Records can only be loaded sequentially from the Start Record position. If you specify a
greater number of records than you have frame buffer space available, the loading process will
fill the buffer and then wrap around leaving the last records transferred in the frame buffer. See
setting the frame buffer size in 3.2.3.4.
In Start Frame, enter the location in the frame buffer where you wish to begin depositing the file
records. Multiple frames will load from that location upward, skipping any locations that are
Write Protected.
3.1.1.2 Special Frame Numbers
The following Frame numbers have special meanings, however they can be saved and loaded in
the usual manner.
• Frame 0 is the Reference Frame
• Frame -1 is the Gain Correction frame, not a true image frame, but rather an array of
gain correction factors.
3.1.1.3 Drag and Drop Data Frame Loading
You can perform a Load Frame operation by dragging and dropping one or more data frame files
from Windows Explorer, or by double clicking the data file name. If you have not already
started the LBA application, using the double click method will start it automatically.
These Drag and Drop shortcuts will work on all Data Frame formats. However, the current
camera configuration must match the camera configuration of the data file that you are
attempting to load. If you Drag and Drop a data file that contains multiple records, all the frame
records will be loaded into the frame buffer up to the maximum size of the buffer. For example:
If you Drag and Drop a file with 20 records, and your frame buffer is sized at 10 frames, then
only the first 10 records in the data file will be loaded.
To perform a Drag and Drop, open Windows Explorer. Highlight the data file(s) that you want
to load. With the Mouse cursor over the file name, press and hold down the left mouse button
while dragging the highlighted files to the LBA-PC application.
3.1.2 File | Save As…
You can save or append data frames in the frame buffer to disk files. All data files saved by the LBA-
PC will have a .lb3/4/5/7 file name extension.
Data files can contain one or more frames of data. Each frame of data is called a Record.
Embedded in each Record is all the information necessary to accurately reproduce the original frame.
Pixel scale, Camera type, Zoom and Pan location, energy and Ultracal values etc. are saved within
each Record.
