Abstract
A method of manipulating information is disclosed in which the data is stored as a digitized image and is retained in image form for various data processing manipulations. A font table is formed having a matrix of fonts correlated with characters and symbols in code form such as ASCII. Desired material in the stored documents is located using pattern-match searching with a parallel processor search engine.
Claims8
A method of data processing comprising
- storing digitized images of document contents including text in at least one font,
- establishing in non-volatile memory a font table including code values of alphanumeric characters and symbols and images of characters and symbols in each font used in the document text, each character and symbol in each font being correlated with the code value for the character or symbol,
- selecting and locating digitized images of selected portions of stored documents to be manipulated by data processing, the step of locating including
- defining a search word which appears in the stored documents,
- entering code representing the search word,
- compiling from the font table a plurality of image words constructed of a sequence of images of characters which are the same characters as the search word and in image in a plurality of fonts,
- comparing the image words with the stored digitized images until a match is found, and
- copying into a memory the stored image of the document in which the match is found;
- and
- processing the selected digitized images.

- selecting and locating digitized images of selected portions of stored documents to be manipulated by data processing, the step of locating each image including
- forming a table of word images selected and copied from stored documents for use as search words,
- displaying the search word images,
- selecting a search word image which appears in the stored documents from the display of word images,
- comparing each selected search word image with the stored digitized images until a match is found, and
- copying the stored image of the document containing the word into volatile memory;
- and
- processing the selected digitized images.
