This selector restricts the area on the page where the text data is located. This is the easiest way to extract data from documents with a fixed template (forms, driver licenses, passports, and so on).
The selector properties define which borders of the region should be taken into account to restrict the extracted data.
If selected, only characters to the left of the left border will be extracted.
If selected, only characters to the right of the right border will be extracted.
If selected, only characters below the top border will be extracted.
If selected, only characters above the bottom border will be extracted.
This selection extracts all characters above the bottom border, and between the left and the right borders of the selector region.
Expert mode keyword:
boundary: left | right | bottom | top
Note: The selector
boundary without arguments is equivalent to
boundary: left right bottom top. This means only characters inside the selector region will be extracted.
