-adii --detectInvertedImage
no   Detects whether the image is inverted (white text against black background).
-ido --detectImageOrientetion
no   Detects page orientation during layout analysis, and if it differs from the normal, rotate the image.
-adp --dontDetectPictures
no   The pictures are not detected during layout analysis.
-adt --dontDetectTables
no   The tables are not detected during layout analysis.
-afoe --fastObjectsExtraction
no   Layout analysis will speed up, but its quality may deteriorate.
-fda --flexiFormsDA
no   Detects all text areas on the page, including small text areas of low quality and text on diagrams and inside pictures.
-aftda --fullTextIndexDA
no   Detect all text on an image, including text embedded into the image. Reading order is not changed to provide ability for further full-text search.
-apcw --prohibitClockwiseRotation
no   Disables clockwise page rotation when selecting the page orientation. This key can not be used with the -apccw or -apud key.
-apci --prohibitColorImage
no   Uses only black-and-white plane during page layout analysis.
-apccw --prohibitCounterclockwiseRotation
no   Disables counterclockwise page rotation when selecting the page orientation. This key can not be used with the -apcw or -apud key.
-apma --permitModelAnalysis
no   This key is obsolete. It is ignored.
By default model analysis is permitted. If you would like to prohibit model analysis, please use -aprma key.
-aprma --prohibitModelAnalysis
no   If this key is not used, typical variants of page layout will be gone through during page analysis and the best variant will be selected, which can improve recognition quality. If the best variant of page layout cannot be selected (or if this key is used), standard page layout analysis will be performed.
-apud --prohibitUpsidedownRotation
no   Disables upside-down page rotation when selecting the page orientation. This key can not be used with the -apcw or -apcw key.
