Changes from Version 15 to Version 16

Highlights

L_AutoBinarizeBitmap coverts a colored image into a image automatically, without losing important image features such as text. This function uses several pre-processing and threshold operations which enable the user to extract the key features of any colored image. It can be adjusted to be suitable for a specific input device,  such as a scanner or camera. It is ideal for making unclear document images more readable. This function is especially useful for improving recognition results (OCR, Barcode, OMR, ICR).

L_DeskewBitmapExt uses fast pre-processing algorithms to provide the highest possible deskew accuracy,  without sacrificing speed.

L_ColoredPencilBitmapExt is a new smart artistic filter that produces a very realistic pencil stroke effect. The numerous  parameter settings enable you to change the style so significantly that the results look like completely different filters.
