Readiris converts scanned images, image files and PDF files into editable text documents and text-searchable PDF documents. In order for Readiris to recognize the text in your images, you need to select the correct recognition options.
By far the most important recognition option is the document language.
To select the document language:
Click the language list, and select your document language.
To access the complete list of available languages, click Other Languages.
Tip Readiris Pro: in case you want
to recognize documents in multiple languages, make sure to select the
language with the largest character set. E.g. if you want to recognize
a document that contains both English and French text, select French as
document language. This way, the accents will be recognized correctly.
When you are processing documents that only contain numbers and almost or no text, then it is recommended to select the Numeric option:
Click the language list and select Other Languages.
Then select Numeric at the top of the list.
When this option is selected Readiris only recognizes the numerals 0-9 and the following series of symbols:
+ plus sign |
* asterisk |
/ slash |
% percentage sign |
, comma |
. period |
( opening parenthesis |
) closing parenthesis |
- hyphen |
= equation sign |
$ dollar sign |
£ pound sign |
€ euro sign |
¥ yen sign |
|
When you are processing Cyrillic, Slavic, Greek or Asian documents that also contain "Western" words written in the Latin alphabet - such as proper nouns, then it is recommended to select one of the available Language pairs.
Language pairs are always combined with the English language and are available for Russian, Byelorussian, Ukrainian, Serbian, Macedonian, Bulgarian and Greek.
Note: when processing Asian or Hebrew documents, mixed characters sets are used automatically.
To select a Language pair:
Click the language list and select Other Languages.
Select the required language pair in the (primary) language list.
When specific pages use a different language than the overall document, you don't need to define a secondary language. You can apply a different language to those pages.
Select the pages in the Pages panel, Ctrl-click them and use the command Language to assign another language than the overall document language to that/those page(s).
Pages with a different language than the overall language are marked in red in the Pages panel.
Unlike secondary languages, there are no limitations here.
Note: the tooltip of each page in the Pages panel indicates which language applies to that page.
When your documents contain text in multiple languages, it is recommended to select a main recognition language, combined with several Secondary languages. You may select up to 4 secondary languages:
Click the language list and select Other Languages.
Select the Primary language.
Cmd-click to select the Secondary languages.
The list of secondary languages changes depending on the selected primary languages.
Note: do not select languages that do not apply; the bigger the character set, the slower the recognition and the higher the risk of OCR errors.
