Getting Started

3.1

Start the GUI

3 Getting Started

To start the GUI, either double click the LuraDocument PDF Compressor taskbar icon
Windows® start menu entry

or use the

LuraTech  LuraDocument PDF Compressor  PDF Compressor.
When you start the GUI for the first time you will see an empty list:5LuraDocument PDF Compressor Enterprise

3.2

3 Getting Started

Add Entries to the List

There are several ways to add new entries. Here we describe an easy one:
Open the Windows® Explorer and drag & drop a file or a folder to the list window. The new entry
will be setup to convert the given file (or all files within the given folder) to PDF output which will beplaced next to the corresponding input file.1

3.3

Run Jobs

There are several ways to start jobs given by the list entries. Here we describe just one:
Select the entry you want to start and push the start button
from the toolbar. The status of the entry
will change from stopped via starting to working, and back to stopped when the job is finished.
Whenever the job is running, you can abort it by pressing the stop button
from the toolbar. It may
take some seconds, until the conversion has been aborted. Any incomplete PDF output file will be
removed.

3.4

Remove List Entries

You can close the GUI without saving your current job list. The list will reappear exactly the same
when you open the GUI again2. To remove an entry from the list, select it and push the delete button
from the toolbar.

1

Changing the default properties can change this behavior. The explanations given here are related to the factory default settings.

2

The current list is instantly stored within the system to make it available to the underlying PDF Compressor service.

4 Set Up Job Entries

Set Up Job Entries

You can edit a job entry’s properties once it is added to the list. The properties dialog window can be
opened by any of the following actions:

Double-click the corresponding entry within the list.



Use the context menu associated with the list entry.

Select the entry and use the toolbar’s properties button

Select the entry and use the menu Entry  Properties.

.

Within the properties dialog you can change the name of the entry to make it easier for you to identify
the related job. The entry name is also used within the log file to identify information, warnings anderrors.

4.1

Configure Processing Mode

The Mode tab lets you configure the overall compression or signature mode for the related job. The
standard setting is MRC compression (Mixed Raster Content compression) which applies the
LuraDocument PDF compression technique to rasterized (scanned) input. (PDF files will be rasterized
before they are passed to the compression engine.) In addition there are special modes available for
PDF input and digital signatures, as described below.

7

LuraDocument PDF Compressor Enterprise

4 Set Up Job Entries

1. Select MRC compression if you want to compress scanned documents regardless of theirformat. Compression is done by separating the content into three layers (text, fore- andbackground) and individually processing each layer with optimal compression algorithms.
Under this mode there are several other settings, like OCR.
2. Select PDF optimization if you would like to optimize PDF documents that mainly containbitonal (black/white) or color images. Optimization is done by recoding bitonal and/or color
images with more efficient MRC compression algorithms. The structure of your PDF
document will remain unchanged, preserving all meta data.
Note: PDF optimization mode can be used to convert a very limited set of PDF files to PDF/A.
In most cases this only works if the PDF input file was created by a scanner and mainly
consists of page images.
3. Select PDF(/A) conversion to convert digitally created PDF and Office documents to PDF or
PDF/A. This mode is only available in case you have the Born Digital Conversion module
installed and a valid license for this optional module.
4. Select Digital signatures to apply digital signatures to the given input files. This function
requires a qualified signature card, a connected card reader with PIN input pad, and its drivers
to be installed as well as a valid license for the optional signature module.

4.2

Configure Input Data

8

LuraDocument PDF Compressor Enterprise

4 Set Up Job Entries

The Input tab lets you configure which input documents should be converted to PDF format. Currently
TIFF, JPEG, JP2 (JPEG 2000), PDF, BMP, and PNM formats are accepted for input files. Multipage
TIFF and PDF files are recognized and converted to multipage PDF documents.
Choose File if you want to convert a single file, or Directory if you want to convert all files within thegiven folder3. The browse button
lets you select the file or directory4. You cannot use mapped
network drives to specify the input file or directory. The underlying PDF Compressor Service has noknowledge on mapped network drives. Instead you can specify the network share using the syntax\\host\share\dir. Please change the Logon settings of the LuraDocument PDF Compressor
service in the Windows service manager to give sufficient access rights.
1. When Directory is selected, you have the following options:a. Enable Include subfolders if the whole directory sub tree should be converted.
Otherwise only files directly within the given folder will be processed.
b. Enable Delete empty folders if you have selected Include subfolders and want to clean
up the input sub tree. This can be useful if you configure a setup that moves or deletes
all processed input files. Once all files of the given job have been processed, theoutput folder will be examined and all empty subfolders will be deleted. If the input
folder is a hot folder (see next item), the cleanup process will be performed whenever
the hot folder becomes idle, i.e. when no more files are found to be processed at the
moment.
c. Enable Check every <number> seconds to make the given folder a hot folder, i.e. to
let the job check that folder frequently for newly generated files (e.g. by an external
3

Whenever you use the browse button, type in the path manually, or change it by drag & drop, PDF Compressor automatically checks, if thepath represents a file or directory. Note that this checking might take some time, if the element is located on a net share.

The text edit window for the input path accepts file drag & drop: Just drag & drop a file or folder from the Windows® Explorer into thiswindow.

scanner or capture software). A job that has this options enabled will never stop
automatically, since it keeps on monitoring the given folder. You have to stop it
manually.
This option only makes sense, if you delete successfully converted input files, or movethem into another folder. See Section 4.4.
d. Enable Merge all pages if all pages from all processed files of a folder should be
converted to a single PDF output document. The output file will be named<name_of_the_input_folder>.pdf. The input files of a folder will beprocessed in alphabetical, case-sensitive order. This defines the page order of theoutput PDF.
This option can be used to merge pages from scanners that put numbered single page
files (like page000.tif, page001.tif, etc.) into a single folder.
e. Input file formats can be selected from the given list. The format is derived from thefile’s extension. Note that different sets of file types are displayed in the MRC
compression, PDF optimization and PDF/A conversion modes.
2. Resampling lets you change the input’s resolution. The Minimal and Maximal dpi settings
handle these requirements. Whenever the resolution of the input files is outside the given [min,max] range, the resolution will be changed by resampling to the minimum value or the
maximum value.

4.3

Configure Output Data

The Output tab lets you configure PDF output options and where the generated PDF files should beplaced. In addition PDF metadata can be specified that will be embedded within the output PDF
document.

The data entered in the fields of PDF Metadata will be embedded in the output PDF document. You
can
find
that
information
withinAcrobat®
Reader®
under
the
menu
File  Document Properties  Description. It is possible to put certain escape sequences into the
PDF Metadata fields that will be substituted by information such as file name, number of pages, date,time, etc. The help button
displays a list of all possible substitutions.

4.4

Configure Options

The Option tab lets you configure special action on processed input files. It also defines the priority of
the job.

11

LuraDocument PDF Compressor Enterprise

4 Set Up Job Entries

The Job priority can be set to values from 1 (highest) to 10 (lowest). Lower numbers correspond tohigher priority. This setting is only available when the menu File  Priority Processing Order isenabled. The toolbar icon
can also be used to switch Priority Processing mode on and off5.
If Priority Processing Order is enabled, jobs with higher priorities are processed before lower priority
jobs.
All jobs with the same priority are executed concurrently by processing its job units in interleavedorder: Once a unit is done, the next unit of the next job with same priority is processed. When morethan one CPU core is licensed and enabled, more than one job unit will be processed at the same time.
A job unit contains all input files that contribute to one output PDF document6. If input merging isenabled , this includes all files that are merged into a single document, otherwise it is just one single
input file.

4.5

Configure Header and Footer

The Header and Footer tabs let you configure additional text that is added to each output PDF page.
This can be used to add labels, e.g. “Draft”, page numbers, date and time of the conversion, and otherinformation. The given text can be customized in font, font face, color size and position. The Header
and Footer tabs are identical up to its titles.

5

All entries of the job list must be stopped to change the Priority Processing mode.

6

Note that an output PDF document may be distributed among multiple PDF files if output splitting is enabled.

This feature is currently not supported when creating PDF/A documents.

4.6

Configure Watermark

The Watermark tab lets you add an additional image (e.g. a company logo) to each of the output pages.
The position, size, scaling and transparency of the added image can be specified. Transparency is notsupported when output to PDF/A.

4.7

Configure Encoder Options

The Encoder tab lets you configure the options for the image compression. These include the overall
quality setting, adoption to special input document types, settings for the Acrobat® compatibility andother options.

1. Quality: A higher quality value results in higher PDF image quality, but PDF file sizes will
increase. A lower quality value corresponds to higher image compression ratios and thus tosmaller file sizes.
2. Document Class: You can use different classes to optimize the compression results for specificinput document types:a. Standard should be used for all purpose input documents. This is the default setting.
b. Check should be used to obtain better quality if the input document contains a lot offine structures like lines, thin graphical drawings, etc.
c. Photo turns off the text detection. Everything is put into the background image layer.
This should be only used if your input is of image type: no or only few text and/orgraphics.
d. B/W (black & white) turns off image color. Your documents are stored in black andwhite color, as if you have sent it by a b/w fax machine.
3. Default Resolution: If the input image file does not contain any resolution information, thevalue (in dpi) given here will be used. In addition this value is used when an input PDF file israsterized (PDF files do not have specific resolution information in general).
4. Compatibility: PDF documents produced by PDF Compressor need at least Acrobat®
Reader® 5.0 to be properly viewed.
Acrobat® Reader® 6.0 is able to handle JPEG 2000/Part1 image compression.
Acrobat® Reader® 7.0 additionally supports large page sizes (> 200 inches).

PDF/A: In 2005 the International Standard ISO 19005-1 “Document management –Electronic document file format for long-term preservation – Part 1: Use of PDF 1.4 (PDF/A1)” has been published. PDF/A is a subset of PDF 1.4 (Reader® 5.0 compatibility) for the useof long-term preservation and archiving. The more common conformance level PDF/A-1b isrecommended when using the PDF Compressor to create PDF/A.
There are several restrictions regarding PDF/A. For example password protection is notallowed by the standard.
5. Mask Codec: You can select between JBIG2 and Fax G4 compression for the text mask.
JBIG2 has a better compression performance compared to Fax G4, resulting in smaller filesizes. Please mind that there is a lossy and a lossless JBIG2 compression. JBIG2 options canbe set within the Advanced options dialog.
