To manually zone horizontal Asian text, use the usual text zone type. Please draw rectangular zones with this tool.
The zoning tool can however be used to force vertical Asian recognition by manual zoning. This places all detected texts into text zones by choosing an Asian recognition language you set Asian OCR to run in these zones and that can automatically detect and transmit the text direction, coping with mixed areas of horizontal and vertical texts on a page. Layout and zoningĪuto-layout and auto-zoning are recommended for Asian pages. Verify language choices cannot be used when this option is set, nor can individual language choices be made. Choose Asian languages or Latin-alphabet and Asian in the drop-down list to have these languages considered during the detection. This is useful for unattended processing where input documents may be in different languages. The Asian languages can be processed with the option Detect single language automatically. Detection is more robust with at least several lines of text and a minimum of embedded English text.
Verification takes place during image pre-processing, so the required recognition language must be set before image loading. The last category means Japanese, Chinese or Korean characters were not detected. It cannot distinguish between Traditional and Simplified Chinese or between non-Asian languages. It works at page-level and identifies four categories: Japanese, Chinese, Korean and non-Asian. Language verificationīeside the language list the option Verify language choices invokes automatic language detection that warns of differences between a detected language and the language setting. The program can handle all these in the output they appear right-rotated. Vertical text in Japanese and Chinese may have English embedded in different orientations: Asian OCR can handle short embedded English texts without English being explicitly set this is not designed for longer English texts or for texts in other Western languages. You should select only one of these languages at a time and avoid a multiple selection with other languages. The four Asian languages are listed alphabetically with the others in the Options/OCR panel. You may be required to insert a Windows system disk.
Operating systems supported by OmniPage can handle Asian languages, but if East Asian language support was not selected during system install, it must be added from Control Panel / Regional and Language Settings / Languages / Supplemental language support / Install files for East Asian languages. Japanese and Chinese texts can be horizontal (left-to-right) or vertical (top-to-bottom, right-to-left) Korean text is always horizontal. For smaller characters, 400 dpi should be used.
Minimum is 30 x 30, that is 10.5 points at 300 dpi. The ideal font size for body text is 12 points, scanned at 300 dpi, resulting in characters with around 48 x 48 pixels.
