Visual Integrity Conversion Server

server architectureThe Visual Integrity Conversion Server, a powerful command-line automation server, converts PDF and PostScript pages into industry-standard vector and raster formats.

It's impressive flexibility and easy customization make automating projects requiring page conversion quick and easy. The Conversion Server uses PostScript and PDF files, application data or print streams as input and outputs most industry-standard vector, page and image formats.

Mature and robust, the Conversion Server is capable of scaling from simple departmental workflow projects to the most demanding enterprise volumes. The simple command line interface combined with a conversion profile makes harnessing the power of the Conversion Server a snap.

No Printer Driver. You'll enjoy unbeatable performance because the Conversion Server does not use an intermediate printer driver, which many other solutions rely on to the detriment of performance. Being able to skip this intermediate step accelerates the process and boosts performance significantly while guaranteeing clean throughput. The command-line server can be scripted to support conversion of files into industry-standard vector and image formats.

Beyond PDF. PDF is all around us these days but if you have legacy applications, you may still be in need of solutions to convert PostScript or EPS. Talk to us. We can help with scaleable, high volume solutions for your legacy PostScript applications.

Try the Conversion Server - Register for a free trial. We're standing by to help. Start by downloading an evaluation version or send us a test file. We'll convert it and let you know any special edits you'll need to make to your conversion profile. Make sure you tell us a bit about your project or intended use.

Choosing a Conversion Server

To select your Conversion Server, choose your Input format. This will be PDF, PostScript, EPS, AI or a print stream. Then, choose your output format and select the module that contains it. The Conversion Servers are offered in two ways. You can buy a perpetual license with optional annual support or you can take an annual subscription. The differences are outlined below. If you have questions, please contact us via email or phone and we will help you find the server that is right for your requirements.

Perpetual License

Choose the perpetual license if you plan to set your project up once and let it run without further major development work. Annual Support is optional but recommended if your project will evolve over time.

Annual Server Subscription

The Annual Server Subscription includes the Server license, all updates, priority support and a low cost of entry. The subscription must be maintained for the life of the project. You have the right to use the software as long as you are an active subscriber.

FLY Batch is for process automation, integration and server-side automation. The powerful batch executable allows you to invoke the DLL engine via the command line. The functionality is embedded in the standard PDF FLY and META FLY downloads for evaluation.

In order to enable the batch conversion engine for use via the command-line, you must add the installation path for the software to your %path% variable. This can be done via the Control Panel -> System -> Advanced->Environment
%path% variable

By default PDF FLY is installed in C:/Program Files/Visual Integrity/PDF FLY
This installation path must be added to the %path% directory.
On the command line you can do this by:
Set path=%path%;”C:/Program Files/Visual Integrity/PDF FLY v__” (fill in version number)

FLY Batch for PDF and PostScript (Adobe PostScript, EPS and PDF input)

  • To convert PDF files, run pdf2xxx. Settings for pdf2xxx are defined in the pdf2xxx.ini file.
  • To convert PS or EPS files, run ps2xxx. Settings for ps2xxx are defined in the ps2xxx.ini file.

FLY Batch for Metafiles (WMF and EMF input)

  • To convert WMF files, run wmf2xxx. Settings for wmf2xxx are defined in the wmf2xxx.ini file.
  • To convert EMF files, run emf2xxx. Settings for emf2xxx are defined in the emf2xxx.ini file.

General Usage:

  • See the “options” PDF file for an overview of the variables and their use. You can open and edit the .ini files with a text editor like Notepad. The pdf2xxx.ini file is used for PDF and the ps2xxx.ini file is used for PostScript and EPS.
  • The extension of your source file determines which conversion filter will be invoked.

So, for example, to convert myfile.eps to myfile.svg run: ps2xxx myfile.eps myfile.svg.

To convert myfile.wmf to yourfile.jpg run: wmf2xxx myfile.wmf yourfile.jpg.

To convert foo.pdf to for example foo.gif run: pdf2xxx foo.pdf foo.gif

pdf2cad will convert a “batch” of files when requested by the user. It’s as easy to convert an entire directory of files as it is to convert one file. That said, sometimes, companies want to use a watch folder or use scripts to automate conversion. When this is required, you’ll want to use FLY Batch. PDF to DXF is one of the modules in FLY Batch, a command line driven batch conversion engine that’s easily scripted for automated, central, high-volume or real-time processing. It runs on Windows, Mac, Linux and UNIX platforms.

For fonts to appear correctly in a vector output file, the same font with the same naming convention must be on both systems. Sometimes, any mismatch can be resolved through font mapping. If you need support on adding fonts to your environment please contact Custom font mapping is available as a service but is not covered by the standard Advantage Support Subscription.

By default the fontname used in the PostScript or PDF file is used also as fontname in the vector output file. Using the Font Mapping dialog you can change this by creating a mapping between the original fontname and the fontname you want to use in the vector output file.

Fonts are not embedded in the vector output formats. Most of the vector output formats do not support embedding of font data.

For SVG only we have hooked in the font embedding option for PDF files which has the embedded fonts. Please contact us if you want to know more about this option.

It is easy it is to create a PostScript file from virtually any application on a PC. Most PC’s are likely to have a PostScript printer driver configured in its printers settings. If not, you must Install a PostScript Printer Driver before going any further.

  1. Open your file within your application and then select “File…”, “Print”
  2. Choose your PostScript printer. Note that you can use any PostScript driver included with Microsoft Windows without having the actual printer since you will simply be printing to a file.
  3. Press “OK”  to print to file. Note that the PostScript tab under Properties should be set to Encapsulated PostScript (EPS) for best results.
  4. You will be prompted for a file name and location. If you do not assign .ps as the extension, the default in Windows will be .PRN. Both are valid input extensions.
  5. Open your Visual Integrity software and when prompted for a PostScript file to convert, go to the location chosen in Step 4 and select the new .ps or .prn file for conversion.


  • The extension does not matter – Some systems give printer files a default extension, like .prn or .plt. This does not matter. If the file has been created using a PostScript printer driven, the result will be a PostScript file that Visual Integrity software can convert.
  • Watch out for PCL: Most HP printers use a printer language called PCL. The default mode on HP PostScript printers is usually PCL. PCL can not be converted by TGC. Be sure that your HP printer is in PostScript mode to ensure a successful conversion.
  • Save directly as PostScript or EPS files – Many applications allow you to save your files as PS or EPS through their “Save as…” menu. A few even produce PostScript by default. This results in good input for our conversion engine.
  • Fonts – Try to use standard PostScript fonts like Helvetica and Times New Roman. Non-PostScript fonts, such as Type 1 fonts and TrueType fonts should be embedded so that the text data is available in the PostScript file. This gives our software the best chance to preserve the fonts during conversion.

The font glyphs of the 13 standard PostScript fonts are included.

If you need to convert to an image format or the text to curves/polys (= emulate) in a vector format either the font must be one of the 13 standard fonts or the font should be embedded within the PDF or PostScript file. Contact if you want to add font glyphs.

13 Standard PostScript fonts:

  • Courier (Regular, Oblique, Bold, Bold Oblique)
  • Helvetica (Regular, Oblique, Bold, Bold Oblique)
  • Times (Roman, Italic, Bold, Bold Italic)
  • Symbol

Using the Conversion Server

Choose Input Format

Input formats supported on the command line are PDF and PostScript.

Select Output Format

The Conversion Server is capable of producing vector formats, bitmap images and text from the input formats. Examples are PDF, WMF, SVG, PNG, TIFF and Unicode text.

Ensure Fonts are Mapped

A common trap for conversions is a font mismatch. Due to licensing issues, fonts can not be embedded in documents. They can be mapped or substituted. Take care in this area to ensure perfect results.


A sample .ini file is provided with the command-line tool. It can be used as a base to understand the many options and to tailor them to your needs.

To convert foo.pdf to foo.svg run: pdf2xxx foo.pdf foo.svg

Tutorial: How the Conversion Server Works

  1. Register for an evaluation version of the Conversion Server
  2. You will receive a link to PDF FLY. This product includes the includes the complete Conversion Server engine. You can use the desktop version to test file conversions and you can access the engine to test your integration. It has everything you need to full evaluate the conversion server.
  3. To test the integration, set-up the command line executable by adding the installation path of PDF FLY to your %path% variable.
  4. Edit the Options file (*.ini) with custom conversion settings if required
  5. Convert
  • To convert PDF files, run pdf2xxx (Options file is pdf2xxx.ini).
  • To convert PS or EPS files, run ps2xxx (Options file is ps2xxx.ini).

“It works perfectly! Our test and the import-check in our system were positive. We are very happy.”, Claus-Juergen Neumann, BASF – The Chemical Company.

BASF Global R&D Information Technology and Information Management is using FLY Batch with custom Caddy TIFF support.
