Members

Member	Value	Description
Default	0	The default option means the default behavior, when no flags are defined.
DisableTextOrientationDetection	16	Setting this flag disables text orientation detection in the text extraction engine.
ExactWordLineMatching	2	Setting this flag forces the engine to only place words on the same line if the vertical coordinates of their bounding boxes are matching exactly. Otherwise, the text extraction will apply threshold value when matching the vertical coordinates of words bounding boxes.
IgnoreRotatedText	32	Setting this flag forces engine to ignore text that is rotated in reference general text orientation.
IgnoreToUnicodeMapFormat	4	Setting this flag forces the engine to ignore the format of ToUnicode table in Simple Fonts in cases where multibyte notation is used. Otherwise, the text extraction will only use the ToUnicode table with Simple Fonts if the single-byte notation is used according to PDF specification.
IgnoreUnexpectedWhitespace	1	Setting this flag forces the engine to ignore whitespace characters that intersect bounding box of a recognized word. Otherwise, the whitespace character is included as a regular word component based on its position relative to the word bounding box.
PreserveLayout	8	Setting this flag forces the engine to try and preserve the text layout as presented on page.
