Step 1: Image processing keys

--calcSkewByBlackSquares

  • The skew angle for an image is calculated using information about the so called “black squares”.
Key Parameters Default
-icsb no
–calcSkewByBlackSquares

--colorJpegQuality

  • Specifies the value of the JPEG quality in percent for saving color pictures to JPEG format files.
Key Parameters Default
-icq JPEG quality in percent 75
–colorJpegQuality

--dontCorrectSkew

  • The skew angle for an image is corrected during the preparation process.
Key Parameters Default
-ics no
–dontCorrectSkew

--createPreview

  • Creates preview page for the prepared image.
Key Parameters Default
-icp no
–createPreview

--grayJpegQuality

  • Specifies the value of the JPEG quality in percent for saving gray pictures to JPEG format files.
Key Parameters Default
-igq JPEG quality in percent 25
–grayJpegQuality

--imageCompression

  • Specifies the compression type for ABBYY FineReader Engine temporary image files.
Key Parameters Default
-ic ABBYYLossless
Lossless compression. This compression type provides a medium image file size and the quality of the original image. 		ABBYYLossless
JpegLossy
JPEG lossy compression. This compression type provides the least image file size and the worst image quality.
Uncompressed
This compression type provides the largest image file size, the quality of the original image, and the least processing time.
–imageCompression

--invertImage

  • Inverts the colors of the prepared image.
Key Parameters Default
-ii no
–invertImage

--mirrorImage

  • Mirrors the prepared image around its vertical axis.
Key Parameters Default
-im no
–mirrorImage

--despecleImage

  • Removes small garbage areas from the prepared image.
Key Parameters Default
-id no
–despecleImage

--convertToBWImage

  • Leaves only black-and-white planes in the prepared image.
Key Parameters Default
-ibw no
–convertToBWImage

--overwriteResolution

  • Allows to overwrite resolution of the prepared image.
Key Parameters Default
-ior no
–overwriteResolution

--previewHeight

  • Specifies the height in pixels of the preview page.
Key Parameters Default
-iph height in pixels of the preview page 90
–previewHeight

--previewWidth

  • Specifies the width in pixels of the preview page.
Key Parameters Default
-ipw width in pixels of the preview page 64
–previewWidth

--imageRotation

  • Specifies the rotation angle to apply to the image during preparation.
Key Parameters Default
-ir NoRotation
No rotation.
Clockwise
Rotation 90 degrees clockwise.
Counterclockwise
Rotation 90 degrees counterclockwise or 270 degrees clockwise.
Upsidedown
Rotation upside down, or 180 degrees.
–imageRotation

--dontSmoothcolorImage

  • Specifies whether a color image should be smoothed. Smoothing the image reduces its size but at the cost of its quality. This key is only taken into account if the -ic key is ABBYYLossless.
Key Parameters Default
-isci no
–dontSmoothcolorImage

--xResolutionToOverwrite

  • Specifies the value in dpi to which the horizontal resolution of the image is reduced if the -ior key is used.
Key Parameters Default
-ixr horizontal resolution in dpi 300
–xResolutionToOverwrite

--yResolutionToOverwrite

  • Specifies the value in dpi to which the vertical resolution of the image is reduced if the -ior key is used.
Key Parameters Default
-iyr vertical resolution in dpi 300
–yResolutionToOverwrite
  • Note. Full keys are marked by italic.
