· Create Object Streams so the output file is smaller
Installing and Uninstalling Neevia PDFmerge/split
Before installing and/or using this product, please make sure you have carefully read the copyright notice and agreed to all of its terms. If you have any questions about the licensing agreement, feel free to call (954) 981.9252 or send an email to sales@neeviaPDF.com.
To install Neevia PDFmerge/split:
download and save the http://neeviaPDF.com/prods/PDFmerge_setup.exe file onto your hard drive. After downloading the file, double-click on it and follow the instructions. The installation procedure automatically detects your operating system, copies the needed files into your system directory and installs Neevia PDFmerge/split.
Unattended installation:
To perform an unattended (silent) installation launch the PDFmerge/split installer with /sp /very silent /norestart command line switches. Here is the full list of supported switches:
/SP
Disables the "This will install... Do you wish to continue?" prompt at the beginning of Setup.
/SILENT, /VERYSILENT
Instructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When Setup is very silent the installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with '/SP' command line option explained above). If a restart is necessary and the '/NORESTART' command is not used (see below) and Setup is silent, it will display a “Reboot now?” dialog. If it's very silent it will reboot without asking.
/NOCANCEL
Prevents the user from canceling during the installation
process, by
disabling the Cancel button and ignoring clicks on the close button.
Useful along with /SILENT.
/NORESTART
Instructs Setup not to reboot even if it's necessary.
/DIR="x:\dirname"
Overrides the default directory name displayed on the Select Destination Directory wizard page. A fully qualified pathname must be specified.
/GROUP="folder name"
Overrides the default folder name displayed on the Select
Start Menu Folder
wizard page.
/user="username", /company="company name", /serial="serial number"
Use these switches to pass the registration info (username, company name and serial number) to the installer.
To remove Neevia PDFmerge/split from your computer:
1. Select Settings -> Control Panel from the Start menu.
2. In the Control Panel click Add/Remove programs and select Neevia PDFmerge/split from the applications list.
3. Click the Add/Remove button to remove the program. A confirmation prompt is displayed.
Unattended uninstall:
To perform an unattended (silent) uninstall, launch unins000.exe from the folder where the application has been installed with /verysilent /norestart command line switches. Here is the full list of supported switches:
/SILENT, /VERYSILENT
When specified, the uninstaller will not ask the user for startup confirmation or display a message stating that uninstall is complete. Shared files that are no longer in use are deleted automatically without prompting. Any critical error messages will still be shown on the screen. When '/VERYSILENT' is specified, the uninstall progress window is not displayed. If a restart is necessary and the '/NORESTART' command isn't used (see below) and '/VERYSILENT' is specified, the uninstaller will reboot without asking.
/NORESTART
Instructs the uninstaller not to reboot even if it's necessary.

GUI - Graphic User Interface
In this window you can select the Graphic User Interface themes. Check Use GUI Themes to enable the Color Scheme. Once that is enabled check either Gradient fill or Solid fill to specify how the color will be displayed.
Using the graphic interface to split PDF files
In order to split files using the graphic interface you need to execute PDFsplit.exe located, by default, under C:\program files(x86)\neeviaPDF.com\PDFmerge\apps.
Click Add files to select the PDF file(s) to be split. In case you want to split all PDF files in a folder simply click the Add folder. For multiple folders click Add Folders. To remove a file from the splitting list, select the file and click Remove. To select an output folder for the split files click the Browse button in the interface above.
After you add your path to the destination folder the following file naming variables can be used:
%fname% - uses the original file name.
%xd - adds numbers to the resulting file name – e.g. %3d% will force PDFsplit to produce files
with names like this: 'filename001.pdf', ... , 'filename010.pdf', ...
%4d will produce: 'filename0001.jpg', ... , 'filename0010.jpg', ...
%bktitle% - uses bookmarks as file names; works only if Split by Bookmarks in the Splitting settings
window is enabled.
Example: C:\MySplitFiles\%fname%3d%.pdf
Output Settings
Before splitting PDF files you need to specify the output settings. To do that click on the Settings button. The interface below will be displayed:
Splitting Settings
This is the window in which you can specify what options to be used during the splitting process.
The followind options are available:
· Split by page;
· Split by page range: you can enter page numbers and/or page ranges separated by commas;
· Split by bookmarks: you can select to name output files according to bookmark titles;
· Extract specified pages: type in the page number(s) you want to extract from the input file
· Extract specified bookmark: type in the bookmark name you want to extract.
When either Split by Page range or Extract specified pages is selected you will have to insert page numbers and/or page ranges separated by commas in the Pages textbox.
The difference between these two options is that Extract specified pages will output one file that contains all pages you specified in the Pages textbox.
Example1: 1-6, 7, 8, 9 - this splits the input PDF into one file containing the first 6 pages and three other files each having one page.
Example2: 1-4, {2} - this extracts the first 4 pages but creates 2 PDF files with 2 pages each.
Example3: 1-4, {3,1} - this splits the input PDF into a 3 page file followed by a 1 page file.
Preserve PDF/A - use this option if the input file is a PDF/a and you need to preserve the standard after splitting.
Optimize output file for Fast Web Viewing - this option restructures a PDF document for page-at-a-time downloading (byte-serving). This is especially important with large documents that can take a long time to download from a server.
Create object streams - use this option if you need your output file to contain object streams which basically means multiple PDF objects inside a compressed binary stream. This will create smaller files.
Keep modified date unchanged - select this option to make the output file keep the same modified date as the input file.
To remove forms, layers, page labels, annotations, article threads, bookmarks, attachments, named
destinations, tagged info from the output file simply check the corresponding option(s) in the
Splitting Settings interface.
