c. high quality switches foreground sub sampling off. Additionally a higher foreground
image compression ratio is used to limit the increase in file size. Color reproduction
for text and lines is further improved. This option may be used to work around
problems with PDF Viewer applications that do not render the standard sub sampled
foreground in full quality.
d. max quality results in maximum text and line color quality at significantly increased
output file size. (No foreground sub sampling and standard compression ratio)
3. There are two JBIG2 options: The first one selects from two different compression schemes:
a. High compression efficiency uses a sophisticated symbol matching algorithm that
obtains very high compression results, especially if the input image contains a lot of
similar patterns (like characters of a font). This option should normally be used.
b. Fast encoding disables the symbol matching, resulting in a slightly faster
compression, but also in larger file sizes.
The second option is only available for high compression efficiency:
c. Lossy encoding gives the smallest file sizes.
d. Lossless encoding gives larger file sizes, but does not change the text mask. Use this
option for 100% quality and to prevent symbol mismatches in case of low resolution
or low symbol quality.
4. Image Coder Options determine which image codec is used for color images embedded into
the layers of the created PDF documents (e.g. text color and background image layer when
page segmentation is applied):
a. JPEG 2000 selects the newer JPEG 2000 compression.
b. JPEG selects the older DCT-based JPEG compression.
c. Automatic determines the selection of JPEG 2000 or JPEG compression based on the
size (in pixels) of the encoded image. Using Adobe™ Reader™, the display of
document pages with large JPEG 2000 images can become very slow or even faulty,
depending on the user interaction such as zooming or panning. To overcome this
problem, the Automatic mode uses JPEG instead of JPEG 2000 compression
whenever the width or height of an image is greater than 5120 pixels.
Note: This option is not available for Reader™ 5 or PDF/A-1 compatibility. These
compatibility modes must use JPEG compression by definition.
Note: This option is not available for Reader™ 6, Reader™ 7, PDF/A-2, or PDF/A-3
compatibility when the Document Class is set to Photo with Quality 11 (lossless). This special
setting features a lossless compression for the page image. Since lossless compression is not
possible with JPEG, this mode always uses lossless JPEG 2000 compression.
5. Page Segmentation Options let you configure advanced options for the LuraTech page
segmentation. These options are only available when page segmentation is actually part of
the processing, i.e. for document classes MRC Standard or MRC Check.
Enable Use layout analysis to detect images on a page to improve the visual quality of a
page. Detected images are excluded from the segmentation process and stored in a single

layer. This gives images a better appearance without any disturbances by segmentation
artifacts. The resolution of the detected images can be controlled as follows:
a. Regular image resolution sets the image resolution identical to the resolution used
for the background image. This obtains the highest compression rates.
b. Increased image resolution sets the image resolution slightly higher than the regular
background resolution. Images become sharper, but file sizes slightly increase.
c. High image resolution sets the image resolution to the maximum possible value to
obtain the best image quality. Compared to increased image resolution the file sizes
are even larger, but still smaller compared to the document class Photo, where no
segmentation is used.
This option is only available in either of the MRC compression modes. The detection of
images on a page does not increase the processing time if OCR is enabled. If the compression
is done without OCR, the detection of images adds a certain amount to the overall
processing time. Enable activate only when using OCR to only use this feature when OCR is
enabled. (So there is no increase in processing time, but advanced image detection will not
be used for job list entries without OCR.)
Note: The PDF layers option present in older versions of PDF Compressor has been moved to
the Advanced Output Options dialog described under Configuring Advanced Output Options,
p. 30.
Note: The PDF input rasterization option present in older versions of PDF Compressor has
been moved to the Advanced Input Options dialog described under Configuring Advanced
PDF Input Options, p. 19.
Setting up the Default Properties
Each job list entry has its own properties settings. There is one additional set of properties that
is not related to any specific job list entry. This set is called Default Properties. They are used as a
template whenever you create a new entry in the list. You can open the Default Properties
dialog by any of the following actions:
Use the toolďar͛s default properties ďuttoŶ .
Use the menu Entry Edit Default Properties.
WheŶ aŶ eŶtrLJ͛s properties dialog is already opened: Unselect the currently selected
entry by clicking outside any entries region within the list window.
The Default Properties dialog is similar to an entries properties dialog. Only the few differences
are described here.

Default Properties has no name that can be edited.
The Start and Stop buttons are missing (there is no related job to run). Instead you can
reset all parameters to the factory default values.

The following syntax can be used to make a template string substitution dependent from a
condition:

otherwise
Currently the following conditions are defined:

C
True if the number of output chunks is greater than 1 or unknown. False
otherwise.
V
True if the value of the last detected barcode (%V) is not empty (a barcode
was detected).
Examples
A) Output chunks: The template
"%F, %[C%?Part %C, %:%]Pages %02P - %02L"

outputs the 10 pages document "MyFile.tif" with a chunk size of 5 pages to
"MyFile, Part 1, Pages 01 - 05.pdf"
"MyFile, Part 2, Pages 06 - 10.pdf"
and the 5 pages document "MyShortFile.tif" with the same chunk size to
"MyShortFile, Pages 01 - 05.pdf"
B) Barcode renaming: The template
"%[V%?%V%:%F%]"
names the output file according to the value of the barcode found in the document (%V). If
barcode detection fails for a document however, the output is named like the input file (%F) as a
fallback.
C) Barcode splitting: The template
"%F - %[V%?%V%:PREFIX%] (%02P - %02L)"
outputs for a doĐuŵeŶt ͞DLJ&ile͘tif͟ ǁith ďarĐodes Η hapter ϭΗ oŶ page ϯ aŶd Η hapter ϮΗ oŶ

Regular Expression Substitution
The regular expression substitution syntax is defined by:
%[<input>%?<regexp>%:<replacement>%]
<input> identifies the input string the regular expression substitution is applied to:
<input>
Description
F
Input file (or directory) name.
File name for single file input processing, directory name when merging files
from a directory into a single PDF output file. The file name is printed
without file extension for PDF metadata, input file renaming, and output file
renaming.
<regexp> is the regular expression. It implements the commonly used syntax for regular
expressions defined as follows:
A regular expression is zero or more branches, separated by '|'. It matches anything that
matches one of the branches.
A branch is zero or more pieces, concatenated. It matches a match for the first, followed by a
match for the second, etc.
A piece is an atom possibly followed by '*', '+', or '?'. An atom followed by '*' matches a
sequence of 0 or more matches of the atom. An atom followed by '+' matches a sequence of 1
36
PDF Compresor Enterprise – Manual
www.luratech.com
info@luratech.com
Setting up Job Entries: 68
or more matches of the atom. An atom followed by '?' matches a match of the atom, or the null
string.
An atom is a regular expression in parentheses (matching a match for the regular expression), a
range (see below), '.' (matching any single character), '^' (matching the null string at the
beginning of the input string), '$' (matching the null string at the end of the input string), a '\'
followed by a single character (matching that character), or a single character with no other
significance (matching that character).
A range is a sequence of characters enclosed in '[]'. It normally matches any single character
from the sequence. If the sequence begins with '^', it matches any single character not from the
rest of the sequence. If two characters in the sequence are separated by '-', this is shorthand for
the full list of ASCII characters between them (e.g. '[0-9]' matches any decimal digit). To include
a literal ']' in the sequence, make it the first character (following a possible '^'). To include a
literal '-', make it the first or last character.
<replacement> is the replacement string to be used to build up the output string if the regular
expression found a successful match. (If the regular expression has no match, the output string
will be a copy of the input string.) In case of a successful match, each character in the
replacement string will be copied to the output string except for the following special
characters:
Sequence
