Overview of Formats

Visual Integrity Formats

Below is a list of all the formats we support. If you are just curious about formats, you can click each to learn more.

Input Formats

All of our input formats are also output formats. They are all vector formats and allow a great deal of control over the conversion of the page.

Output Formats

We support all industry-standard vector and image formats as output formats. Pick and choose which ones you need.

Text Formats

Sometimes text needs to be stripped from a file or precisely placed in an output file. We cover it all.


File Formats

Common Questions About File Formats

File Formats

There are two basic formats for graphics – vector and image. Vector graphics are made up of objects, lines, curves and text while images are made up of a collection of dots or pixels. Images are also referred to as bitmaps or rasters.

Visual Integrity can convert most PDF files into either vector or image formats. It’s important to know which is best for the job you are doing.

If you need to break a PDF file down into objects and text for editing, then you want to choose a vector format. The vector formats supported in our software are DXF, PDF, PS, EPS, SVG, WMF, EMF, CGM, HPGL and MIF.

If you do not need to edit the file and simply want a sharp copy to insert into a document or to publish on a web-site, you’ll want to go with image formats. The image formats that we support are TIFF, GIF, PNG, JPEG and BMP. If you will be printing the graphic on a laser or ink-jet printer, convert at 150 or 300 dpi (dots per inch) resolution. If publishing to a web-site, use 96 or 72 dpi is best for screen display. Keep in mind that the higher the dpi (resolution), the larger the file size. It’s best to use the lowest resolution which achieves the level of quality you want.

Note! Scanned images can not be transformed by vector mode into lines, text and other vector objects because they are not vector source files. Instead, you will get an exact replica of the PDF as an image that can be used as a tracing layer which aids in the duplication effort. To convert scanned images into vector objects, you need a special class of software called “raster to vector”.

WMF, or Windows Metafile, is the original 16-bit metafile format. It is the native vector graphics format for the Microsoft Windows platform. It is also the standard format for scalable graphics in Microsoft Office and many other Windows applications. Even though it has been enhanced and extended as a 32-bit format (EMF -Enhanced Metafile), WMF is still the most widely used and supported metafile format on the Windows platform.

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 Computer Graphics Metafile (CGM) file format is used to render graphics in a wide range of technical applications. It is output by many specialized programs in the aerospace, semiconductor manufacturing, automotive and telecommunications industries. CGM is most commonly used in these organizations for product operation, maintenance, repair and other technical manuals. It is also used in the petroleum industry for mapping, lithology cross-sections, seismic traces and well logs. The U.S. military uses CGM for simple redlining on top of raster (map) data. CGM is a format supported both in print and on-line (IETMS). CGM is typically used for technical illustrations in SGML/XML documentation systems, and now, more and more, for Web-based systems like IETMS (Illustrated Electronic Technical Manuals) and e-Catalogs. Outside of these specialized, technical industries, CGM has largely been superseded by formats such as SVG and DXF. The World Wide Web Consortium (W3C) has developed WebCGM, a profile of CGM enjoying specialized use of on the Web.

Over the years, several different versions of CGM have been spawned to meet the needs of various industries. There are specific industry profiles (ATA, MIL, PIP) and four different levels as well as WebCGM. As a result of this diversification, interoperability is often a problem: the target application is unable to reliably interpret the particular flavor of CGM generated by the source application. Many content creation applications have started outputting Level 3 or 4 CGM. However, many applications on the receiving end have not yet implemented full support for these higher levels.

Visual Integrity helps industry manufacturers, suppliers and software vendors turn graphical data into the CGM format. It does so for many source applications which do not offer CGM output, and also for applications which already do – but are incompatible with the end user’s target application. Input formats include PDF, PostScript, EPS, WMF and EPS.

CGM files generated are compliant with all levels and industry profiles. By default, our software produces the common denominator subset of CGM (we like to call it ‘vanilla CGM’) to ensure optimal interoperability with the viewing, authoring, and publishing environment downstream. This ‘vanilla CGM’ handles files typically produced and used in technical industries.

Notes on Visual Integrity’s Support of CGM:
•    Output supports choice of CGM Levels 1-2-3-4
•    Compliant with ATA, MIL and PIP industry profiles
•    Supports vector graphics, raster images and font-based text
•    Supports both metric and abstract scaling
•    Curves are retained in Level 3-4 compatible output
