KeyView can filter a PDF file using the file’s internal paragraph flow, or by applying a structure to the paragraphs to reproduce the logical reading order as seen on the page. Setting the logical reading order enables KeyView to process PDF files containing languages that read from right-to-left (such as Hebrew and Arabic).
KVLogicalPDF parameter controls the processing behavior. Set the parameter to one of the following values:
|0||Extract the text in the order it is in the file rather than the natural reading order|
|1||This value specifies that paragraphs flow logically and read from left to right. This option should be used when the documents are in a language using a left-to-right reading order, such as English.|
|2||This value specifies that paragraphs flow logically and read from right to left. This option should be used when the documents are in a language using a right-to-left reading order, such as Hebrew or Arabic.|
|3||This value specifies that paragraphs flow logically. The PDF filter determines the paragraph direction for each PDF page and then sets the direction accordingly.|
