"Create PDF from Images": "Deskew" and "Detect skew of image"

Post by Jensen Head »

In the "Create PDF from Images" tool settings, in the "Image Post-Processing Options" tab, there is a "Deskew" checkbox. In addition, in the same tab in the "OCR Image (Enhanced)" window there is a "Detect skew of image" setting.

Am I correct in understanding that the first setting automatically corrects a slight skew of the entire page (within ± 45 degrees), while the second leaves the rotation of the imported page intact, and only helps the OCR engine to detect text lines located at arbitrary angles?

Hello Jensen Head,

Both options do essentially the same - they detect if the image is skewed and straighten it. There are two separate options for this because you may want to deskew the image without running OCR. Also, the second deskew (the one from the OCR settings) is run by the OCR engine.

Regards,
