IPRO Tech, Inc. - LFP File
Format
LFP files (also called load
files) are used to build the image database and to instruct IPRO View how to
display a project’s images.
The image’s file location; file type, boundary, and Bates number
make up the LFP file.
Here are three methods for
creating an .LFP file.
First, the discovery vendor
provides an LFP file upon completion of the imaging phase for a project or
case.
Second, one can use IPRO's
free utility, IConvert.
This is a free download at
http://www.IproCorp.com.
The IConvert tool will
convert many load file formats to either LFP or other software formats, such as
Summation and Opticon. It is a handy tool for people who don't even use any
other IPRO products internally.
Third, manually edit or
create an LFP file using a text editor.
Each record (or line) in the
LFP file begins with a 2-letter code that determines the action the viewer will
perform. To load an image, we will start the line with IM.
Commas separate some parts of
the record along with semi-colons for the rest of the line. The command in the LFP file takes effect
after you load or import the LFP file. (Import > Import LFP File from the
IPRO Tech Utility menu).
Here are two examples of an
LFP record. In our examples, we use the MSC collection. It contains two
documents, two pages each. The volume name is MSC001.
Example 1: Single Page .TIF
files
IM,MSC00014,D,0,@MSC001;IMAGES\
00\ 00;MSC00014.TIF;2
IM,MSC00015,,0,@MSC001;IMAGES\
00\ 00;MSC00015.TIF;2
IM,MSC00016,D,0,@MSC001;IMAGES\
00\ 00;MSC00016.TIF;2
IM,MSC00017,,0,@MSC001;IMAGES\
00\ 00;MSC00017.TIF;2
Example 2: Multi-Page .TIF
files
IM,MSC00014,D,1,@MSC001;IMAGES\
00\ 00;MSC00014.TIF;2
IM,MSC00015,,2,@MSC001;IMAGES\
00\ 00;MSC00014.TIF;2
IM,MSC00016,D,1,@MSC001;IMAGES\
00\ 00;MSC00016.TIF;2
IM,MSC00017,,2,@MSC001;IMAGES\
00\ 00;MSC00016.TIF;2
Note: Because the files are multi-page,
the entire bates range (or image key range) must point to the same .TIF file.
As example, MSC00014 contains both "14" and "15".
Therefore, to view page 15, the computer must display MSC00014.TIF.
The following provides a
breakdown of the fields:
|
Value
|
Description of Purpose
|
|
IM
|
Import code identifier
(Importing New Page/Image database record)
|
|
MSC00014
|
The image key/document id
number
|
|
D
|
Document designation; only
designate the first page of each document.
|
|
0
|
Offset to the Tiff
file. Always 0 for single page
tiff files. When creating
Multi-Page Tiff files, this number will increment for the pages within the
file. (If there is an 11 page
document, the offset would start at 1 and end at 11 and the next tiff file
would start over at 1.
