An image processing apparatus scans an image of a document into image data, splits the image data into a plurality of areas to generate split image data, magnifies the split image data, and aggregates the magnified split image data at least based on a font size of one or more characters included in the split image data.

A method using L processers includes: receiving image data encoded by delta row encoding; dividing the two dimensionally arranged plurality of pixels by M (ML) to make M blocks of pixels; assigning M processers to perform a parallel processing of accumulating the delta data for all the row lines of each of the M blocks of the image data to obtain the accumulated delta data, the accumulated delta data including a total delta between the first row line and the last row line in each of the blocks; obtaining the first row lines in the respective blocks using the total delta one by one starting from the second block; and assigning M+1 processers to perform a parallel processing of decoding using the obtained first row lines to obtain the decoded data and a parallel processing of rendering the image data using the decoded data.

A method of generating a barcode pattern includes: identifying a silhouette comprising a boundary within which a barcode pattern is to be printed; generating a barcode pattern comprising multiple instances of a two-dimensional barcode, in which the instances include barcodes of at least two different sizes; and generating a print file that includes information for printing the barcode pattern within the silhouette.

Provided is a technique that can suitably form a cut line. According to one embodiment, an image forming device includes a line information generation unit and an image forming unit. The line information generation unit generates line information representing a cut line to cut out a main image formed on a recording medium. The image forming unit forms the main image with a non-decolorable material on the recording medium and forms the cut line represented by the line information with a decolorable material on the recording medium. The line information generation unit changes a level of curving of a curve included in the cut line, according to the recording medium.

A printing apparatus includes: a print head; a conveyance device; and a control device configured to perform control of printing a print image, including: obtain image data indicating an input image; generate print data for printing the print image for each line based on the image data, the generating of the print data including: shifting the dots composing the input image in the sub-scanning direction to form the dots composing the print image; and reduce a width of a plain area in the sub-scanning direction of the print medium, the plain area being an area where the print image is not printed over the entire area of the plain area in the main scanning direction on the print medium.

An object of the invention is to solve low productivity of foil-stamping printing due to frequent replacement of foil rolls when the positions of sizes of foil objects are different in a plurality of jobs. A grouping unit groups jobs on the basis of a foil roll which can be attached to a foil stamping device and foil object information. A job sorting unit sorts the grouped jobs on the basis of a sorting policy by group. A foil-stamping print data transmitting unit transmits foil-stamping print data including the foil object, which is extracted from print data to a foil stamping device. A foil roll replacement information output unit outputs foil roll replacement information indicating a timing that a foil roll is replaced.

A printing apparatus for printing on an elongate printing medium includes the following elements: a transport mechanism for transporting the printing medium; a printing unit including a plurality of print heads arranged at intervals in a transport direction; a detecting unit including at least three detectors arranged as spaced from one another for detecting positions in a width direction of the printing medium; a variation history acquirer for deriving, for each detection cycle, a function approximate curve based on positions of the same location in the transport direction of the printing medium detected by the respective detectors, and acquiring from each function approximate curve, and as a variation history, a deviation amount in the width direction in each of the printing positions; a predicted position calculator for calculating, from the variation history, a predicted position in the width direction for each of the printing position; and a printing controller for printing while correcting the position based on the predicted position.

A binary image generation portion binarizes a scanned image and generates a binary image. A specific character position detection portion (a) specifies rectangles that circumscribe a plurality of characters, respectively, in the binary image, (b) detects a plurality of specific characters having longitudinal lines or transverse lines at centers of the specified circumscribing rectangles, and (c) detects, as positions of the plurality of specific characters, center positions of the longitudinal lines or the transverse lines, within a predetermined range, to be detected, in a main scanning direction or a sub-scanning direction. A skew angle specifying portion specifies an alignment direction in which the plurality of specific characters are aligned, based on the positions of the plurality of specific characters detected in the range to be detected, and specifies a skew angle of a document image in the scanned image, based on the specified alignment direction.
