According to a compression method, each dot-matrix font character is divided into a horizontal image including horizontal (stroke) image pattern(s), a vertical image including vertical (stroke) image pattern(s), and a residual image including residual image pattern(s) obtained by removing the horizontal and vertical images from the original character. Then, the Huffman coding is applied to each of a set of the horizontal image patterns, a set of the vertical image patterns, and a set of the residual image patterns, respectively, to produce compressed horizontal codes for the horizontal image patterns in a horizontal Huffman table, compressed vertical codes for the vertical image patterns in a vertical Huffman table, and compressed residual codes for the residual image patterns in a residual Huffman table. The compressed horizontal, vertical, and residual codes are selectively combined into a bit string that represents a compressed form of each character."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for dot-matrix font data compression and decompression","description":"A method and system are provided for compressing and/or decompressing a set of dot-matrix font characters.
