The OCR Shop XTR™/API is a software development kit for closely integrating optical character recognition capabilities in your own software. With support for Linux and UNIX operating systems, the OCR Shop XTR/API incorporates Vividata's powerful image processing technology with ScanSoft's optical character recognition technology to provide powerful and detailed document processing abilities.
Operating System Support:
| Sun Solaris™ SPARC® (Solaris™ 2.7+) |
| Linux™ x86 (Kernel 2.0 and higher) |
For questions about support of other Linux™ and UNIX® operating systems, including Mac OS ® X, please Contact Sales.
Licensing of features
All features are included with the development seat. However, for end user run-time licenses, some features and input/output formats are supported as add-on options and are not licensed in a basic run-time license key. Please Contact Sales (510-658-6587 Ext. 107) for pricing information and details.
Supported input formats
- GIF
- JPEG
- PBM
- PNG
- PPM
- PostScript®
- Rasterfile
- SGI®-RGB
- TIFF

Supported languages and character sets
Text recognition uses a character set and one or more languages. English is the default language and all available languages are included with the development seat. For run-time licenses, additional languages are available as add-on language packs. Multiple languages may be specified for a single document, as long as they use the same character set.
Character sets:
The character set defines the shape of the letters for a particular language.
- Only one character set may be used at a time, based on the chose language.
- English characters are an exception, and may be recognized in conjunction with any character set.
Languages:
- A document using a language with a dictionary is recognized based on the character shapes and with reference to the dictionary file specific to the chosen language.
- A document using a language without a dictionary is recognized based on the character shapes alone, without reference to a dictionary file.

Licensing:
A development seat consists of:
- One copy of the API distribution, including libraries, headers, and sample code.
- Five instances of the software per development seat license.
- One point of contact, meaning one developer working with the API who can contact Vividata™ for support in using the API.
Development seat licenses are regulated by the terms of the contract.
Run-time licenses are regulated via license keys installed on the target system. The keys specify which options are available on a system, along with the number of concurrent instances permitted. Keys are added and updated on a system using a provided utility.
Licensing controls:
- Restriction of the software to the machine ID of the computer (on x86 systems, the MAC address of one of the ethernet cards is used, on SPARC® systems, the hostid is used)
- The number of concurrent instances that will run on that computer
- The languages licensed for that computer
- The features licensed
for that computer (including PDF/PostScript® in, PDF output,
and HTML output)
Overview of the XDOC Output Format
The XDOC output format is a ScanSoft text format which provides detailed information about the text, fonts, images, and formatting in a recognized document, as well as coordinate and confidence values for both characters and words.
OCR Shop XTR offers three types of XDOC output, as specified
by the "dm_out_text_format" option:
| vvTextFormatXdoc | Enhanced XDOC format |
| vvTextFormatXDoclite | XDOC format with no format analysis |
| vvTextFormatXdocplus | XDOC format with style sheet data |
Use the following options to include confidence and bounding
box information in the XDOC output:
| dm_xdc_wconf | Output word confidences in XDOC |
| dm_xdc_cconf | Output character confidences in XDOC |
| dm_xdc_wbox | Output word bounding boxes in XDOC |
| dm_xdc_cbox | Output character bounding boxes in XDOC |
Additional options related to XDOC output include:
| dm_xdc_wbox_pixels | Use pixel coordinates for word bounding boxes in XDOC |
| dm_no_hdr_ftr | Do not label headers and footers |
| dm_accept_thresh | Acceptibility threshold (number corresponds to the confidence values seen in XDOC output) |
| dm_quest_thresh | Questionability threshold |
Please contact Vividata Support for
detailed information about the XDOC format and documentation
needed for XDOC parsing.
