Image normalization rules

The following rules are used for handling the resolution and dimension. The first matching rule governs the conversion:

  1. If the resolution of an incoming image matches the requested resolution, the image is not changed.

  2. If the print size of an image exceeds the value set for the MaxPrintSize parameter (default 60), the image is changed without retaining the original print size. This is done by changing the resolution without resampling the image.

    This parameter is available in the in the C:\Program Files (x86)\Kofax\KIC-ED\MC\Scripts script file.

  3. If the x and y resolutions differ, the image is resampled to the requested resolution (non-quadratic pixel case).

  4. If the resolution value is wrong, it is set to the requested value without resampling the image. This will change the printing size of the image. Such images are not resampled to avoid quality loss. A resolution is wrong if one of the following conditions is true:

    • The resolution is below the MindxResolution (set to 96 dpi).

      If the MindxResolution is not set, ImageMagick returns 72 dpi

    • The resolution exceeds 200 dpi and the width is less than 1500 pixels (19.5cm@200dpi).

    • The resolution exceeds 200 dpi and the height is less than 2000 pixels (25.4cm@200dpi).

  5. If the resolution is higher than requested, the image is down-sampled to the requested resolution.

  6. If none of the listed rules apply, the image conversion depends on the configuration of the ResetResolution value in the image2tif.bat script file available at C:\Program Files (x86)\Kofax\KIC-ED\MC\Scripts. Open the file with a text editor and change the value in the line Set ResetResolution=0. The following are the supported values:.

    0 (default) Resamples the image and changes the resolution.

    Increases the image file size without improving the image quality. Resampling can be a time-consuming operation that often results in lower performance.

    This behavior is the same as in Kofax Import Connector 1.0.0 and 2.0.0 or Kofax Capture Import Connector - Folder.

    1 Changes the resolution without resampling.

    Reduces the print size of the image.

    This behavior is the same as in Kofax Import Connector 2.1.0.

    2 Does not change the image. Best performance.
