If you select this as your zoning method, True Page uses frames to
preserve the positioning of text and graphic elements on the page.
Frames are formatting boxes that are used for designing page
layout; they can contain text or graphics. For example, every
paragraph in a document may be contained within a separate
frame. You can resize frames and move them around to modify
your document's page layout.
• Single Column or Table or One Zone
If you select one of these as your zoning method, True Page does
not use frames to preserve the positioning of text and graphic
elements on the page.
After OCR with True Page, text and graphics appear in frames in the
OmniPage text window regardless of the zoning method used. However,
if the Single Column or Table or One Zone zoning method was used, frames
will be removed when you save a document to another file format.
The next sections explain the difference between True Page output with
frames and without frames.
