  • Patent number: 10970580
    Abstract: To appropriately perform blotting out processing for a portion that a user intends to prevent from being displayed for an electronic document having text information on a character string for search, along with image information. The information processing apparatus according to the present invention, in a case where the electronic document is an electronic document in a format searchable for a character string and where a character string obtained by performing OCR processing for a character image object existing in an area and a character string of an invisible text object existing in the area do not match with each other, a setting unit performs re-setting of an area to which blotting out processing is applied for at least one of the character image object and the invisible text object so that both the character strings match with each other.

  • Patent number: 8842327
    Abstract: A print control apparatus may include a determination unit and a print data generation unit to process variable data. The determination unit determines an imposition method used for defining layout of the variable data including a plurality of pages where stationary content used for a plurality of records and variable content that differs for each record are arranged on one physical page. The print data generation unit generates print data used for arranging the layout of the plurality pages and performs printing. The print data generation unit acquires information for identifying a physical page on which each page of each record included in the variable data is printed based on the variable data and the imposition method determined by the determination unit and generates the print data including the acquired information used for identifying the physical page on which each page of each record is printed.

  • Publication number: 20120188608
    Abstract: A print processing apparatus includes a margin reduction processing unit that saves printed papers by changing the positions of objects such as texts or drawings configuring document data in a predetermined layout direction. The margin detection unit specifies the distances of the margin portions between objects adjacent in the layout direction. The margin reduction effect prediction unit sums the distances of the margin portions, and multiplies the percentage of the summation result relative to the number of pages processed by the number of pages for the entire document to thereby calculate reduction prediction information about printed papers when performing margin reduction print processing. The prediction display unit displays the reduction prediction information about printed papers prior to margin reduction print execution.

  • Patent number: 8225200
    Abstract: An apparatus includes a character extraction unit configured to extract a character string from a document including layout information, a character width acquisition unit configured to acquire space character width information, and a spacing amount determination unit configured to determine a spacing amount of each inter-character space based on the character string extracted by the character extraction unit and the layout information. The apparatus further includes an insertion unit configured to determine whether a space character is to be included in each inter-character space based on the spacing amount of each inter-character space determined by the spacing amount determination unit and the space character width information acquired by the character width acquisition unit, and to insert a space character code into an inter-character space in which a space character is determined to be included.
