| 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 |

| Key | Parameters | Default |
|---|---|---|

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.
