Step 3: Synthesis Keys

Below you can find the description of the synthesis keys of the abbyyocr11 utility.

--correctDynamicRange

  • Image colors will be corrected so that the background is white and the text is black, or vice versa, which improves image quality.
Key Parameters Default
-scdr Auto
No
Yes
Auto
- -correctDynamicRange

--detectBackgroundcolor

  • The background color is detected during recognition.
Key Parameters Default
-sdbc Auto
No
Yes
Auto
- -detectBackgroundcolor

--dontDetectBold

  • The bold-face type is not detected during recognition.
Key Parameters Default
-sddb no
- -dontDetectBold

--dontDetectDropCaps

  • The drop caps is not detected during recognition.
Key Parameters Default
-sdddc no
- -dontDetectDropCaps

--dontDetectFontSize

  • The font size is not detected during recognition.
Key Parameters Default
-sddfs no
- -dontDetectFontSize

--dontDetectItalic

  • The italic-face type is not detected during recognition.
Key Parameters Default
-sddi no
- -dontDetectItalic

--dontDetectSerifs

  • The serif typeface is not detected during recognition.
Key Parameters Default
-sdds no
- -dontDetectSerifs

--dontDetectSmallCaps

  • The small capital letters are not detected during recognition.
Key Parameters Default
-sddsc no
- -dontDetectSmallCaps

--dontDetectSubscriptsSuperscripts

  • The subscripts and superscripts are not detected during recognition.
Key Parameters Default
-sddss no
- -dontDetectSubscriptsSuperscripts

--detectTextcolor

  • The text color is detected during recognition.
Key Parameters Default
-sdtc Auto
No
Yes
Auto
- -detectTextcolor

--dontDetectUnderlineStrikeout

  • The underline and strikeout are not detected during recognition.
Key Parameters Default
-sddus no
- -dontDetectUnderlineStrikeout

--insertEmptyParagraphsForBigInterlines

  • Empty paragraphs are inserted to reproduce big line spacing of the original text. This property is ignored if -spem key is NormalExtraction.
Key Parameters Default
-siep no
- -insertEmptyParagraphsForBigInterlines

--monospaceDetectionMode

  • Specifies the mode of monospaced font detection.
Key Parameters Default
-smdm Auto
The font is detected automatically.
NotMonospace
Sets the font to non-monospaced.
Monospace
Sets the font to monospaced.
Auto
–monospaceDetectionMode

--paragraphExtractionMode

  • Specifies the mode of paragraph extraction.
Key Parameters Default
-spem NormalExtraction
RoughExtraction
SingleLineParagraphsWithSpaceFormatting
SingleLineParagraphsWithWordSeparationOnly
NormalExtraction
- -paragraphExtractionMode

--synthesisLowMemoryMode

  • New CLI 11 R1
  • Enables low memory mode during document synthesis. The FineReader Engine will try to use no more than 600 Mb of memory during document synthesis by loading less pages to memory simultaneously.
  • However, document synthesis may slow down and the quality may slightly deteriorate.
Key Parameters Default
-slmm no
- -synthesisLowMemoryMode

--synthesisPagePoolSize

  • New CLI 11 R1
  • Specifies how many pages can be loaded by document synthesis simultaneously. This option can be used to decrease memory usage.
  • It is recommended to use the value in range from 32 to 64. The more the value, the more the speed of processing.
  • However, it is better not to pass the highest values to this option for processing big documents, as this may lead to an “out of memory” error. The value less than 5 is ignored.
Key Parameters Default
-spps number of pages to be loaded
simultaneously during document synthesis
64
- -synthesisPagePoolSize

--pageLevelFontFormattingDetection

  • Specifies font parameters to be detected at the stage of page synthesis. Detection of font parameters during page synthesis allows to speed up the subsequent document synthesis and decrease memory usage. However, the quality of font detection may deteriorate.
Key Parameters Default
-splffd no
- -pageLevelFontFormattingDetection
  • Note. Full keys are marked by italic.
