This invention discloses an intelligent punctuation compression and line layout method for East Asian text typesetting. East Asian full-width punctuation marks are categorized into six types based on their typesetting function: start punctuation, end punctuation, sentence-end punctuation, sentence-in-sentence punctuation, exclamation / interrogative punctuation, and center punctuation. Each type defines an independent compressibility and compression direction. The categorized punctuation marks are modeled as composite typesetting elements carrying both width flexibility parameters and line break cost parameters. The line break cost and remaining compression capacity are correlated within the same element, and the composite typesetting element is incorporated into the cost optimization process of the line layout algorithm. The selection of line break points and punctuation spacing allocation are jointly determined in the same optimization calculation. A power-law cost function and hierarchical spacing allocation priority (punctuation compression takes precedence over word spacing adjustment, which in turn takes precedence over character spacing adjustment) are employed, and rules are implemented through hard constraints. Vertical layout mode, vertical-center-horizontal unit modeling, and cross-language configurable rules are supported. This invention solves the problem of suboptimal global typesetting quality caused by the decoupling of punctuation compression and line break algorithms in existing technologies.

To provide an information system based on automatic line feed in a handwritten document.SOLUTION: When a user actually writes, a system calculates a standard height and a standard width of a handwritten original. The system detects and deletes an abnormal stroke to prevent a situation where the abnormal stroke affects a division and an identification result obtained thereafter. The system then roughly divides the handwritten original into a plurality of lines using a pre-division unit.
