Recognition module language binaries are xi*.bin, as follows:

For recognizing an English document, the filenames include the identifier ENG:
- xiengb.bin
- xiengc.bin
- xiengd.bin
- xienge.bin
- xiengf.bin (used unaltered for all languages)
- xiengl.bin (used unaltered for all languages)
- xiengp.bin
- xiengs.bin
- xiengz.bin

The files xiengf.bin and xiengl.bin are required, unaltered, for all languages. All other languages have language-specific equivalents of the remaining seven files. The identifier eng is changed as follows:

French: frn
Italian: itl
German: grm
Dutch: dut
Spanish: spn
Portuguese: prt
Swedish: swd
Norwegian: nrw
Danish: dan
Finnish: fin
Portuguese (Brazilian): brz

Application Areas

This recognition module recognizes machine printed text; i.e., from printed publications, laser or ink-jet printers and electric typewriters. Output from mechanical typewriters in good condition may also be acceptable. It should also be used for Letter or Near Letter Quality output from dot-matrix printers, and can also be used for Draft Quality.

Range of Characters

This module supports the characters of the following languages:

English
French
Spanish
Italian
German
Norwegian
Portuguese
Danish
Dutch
Finnish
Swedish
Brazilian

Any of these languages can be combined.

Accuracy Issues

This module is influenced by the page-level trade-off setting, but reduces the three settings to two: FAST is respected, while BALANCED and ACCURATE are merged to one value.

Character Attributes

The omnifont recognition module can detect and transmit character attributes: bold, italic, or underlined text (or any combination of them). It can also detect and transmit character size, and can classify font types into three broad categories: serif, sans serif, and monospaced.
