The Image View of Smart OCR contains the image of an active page
and a panel with actions that can be performed on this image.
Image View usage
The most important action that can be performed is the
Recognition. You can recognize the current page or all pages in
document with a simple click on Recognize menu button. For a full
control you can also click on Preprocess button in order to
automatically deskew the page image and locate regions (see Regions
section bellow) on it. If you directly click on Recognize button
Smart OCR will do these preprocessing steps automatically for you.
Using Image View you are able to specify recognition regions
manually via Draw Text Region and Draw Image Region buttons. This
feature is very handy when you want to recognize just specified
parts from a page instead of full recognition. You can also
manipulate the regions after preprocessing step - you can delete
regions, change their size and/or type, add new regions, etc. All
of these manipulations can be performed by simply using your mouse
and the Image View of Smart OCR.
Regions are areas from image which must be interpreted according
to their type. If the region is a Text Region then its content will
be recognized as text, if the region is an Image Region then its
content will be saved as image.

Below is the list of Image View specific shortcut keys:
