Abstract: A non-transitory computer readable recording medium recording a program for causing an information processing apparatus to function as: a control circuit that determines whether a rendering command of a document created using presentation software is a first-page rendering command, when determined as the first-page rendering command, caches it, generates first-page printable data based on the first-page rendering command and caches it, and when determined as a rendering command of one of second and subsequent pages, determines whether at least parts thereof and the first-page rendering command are in common, and generates, when determined that at least parts thereof and the first-page rendering command are in common, printable data of the one of second and subsequent pages using the first-page printable data; and a communication interface that transmits the printable data to an image forming apparatus.

Abstract: An image forming apparatus includes a control circuit configured to determine whether one of an x-coordinate and a y-coordinate of a path specified in each of successive drawing commands for vector objects is the same, wherein the successive drawing commands are received in incoming printable data. The control circuit is further configured to execute, when there is a new successive drawing command for a vector object in which one of an x-coordinate and a y-coordinate of the path specified by the new successive drawing command is different from the x-coordinate or y-coordinate that has been determined to be the same for previously received successive drawing commands, all of the previously received successive drawing commands having the same x-coordinate or y-coordinate.

Abstract: An image forming apparatus includes a count unit, a count determination unit, a drawing process execution unit, and a count resetting unit. The count unit counts a drawing command for a vector object. The count determination unit determines whether or not a count of the drawing commands obtained by the count unit is equal to or larger than a threshold value. The drawing process execution unit executes, when the count determination unit determines that the count is equal to or larger than the threshold value all the drawing commands for the vector objects counted by the count unit prior to the count being equal to or larger than the threshold value. The count resetting unit resets the count obtained by the count unit when the drawing process execution unit executes the drawing command.

Abstract: An image processing apparatus contains an alpha-blend execution unit and a storage device management unit. The alpha-blend execution unit allocates a memory area in a main memory for an alpha-blend execution to compose transparency properties and carries out the alpha-blend execution in a process to convert a page description language data to an image. The page description language data contains a drawing object having a transparency property and a canvas having a transparency property. The drawing object is drawn on the canvas. The storage device management unit evacuates a memory-image of the canvas in the memory area from the main memory to an auxiliary memory, and reads back the memory-image of the canvas from the auxiliary memory to the main memory when the memory-image of the canvas is required for the alpha-blend execution.

Abstract: The present invention provides for an image-processing device capable of printing oblique lines with an angle of approximately 45 degrees and constant width at any time to obtain a printed image of superior quality. The line-work path information whose coordinate position has been specified by a path processing section (3) is passed to a path control section (4), which stores and controls the path information. When there is an oblique line in the path information to be printed, a 45-degree line determining section (5) judges whether or not the oblique line has an angle within a given range of approximately 45 degrees relative to a horizontal axis or a vertical axis, and once determined as such, the determining section (5) passes the path information to a 45-degree line approximating section (6). The 45-degree line approximating section (6) secures and fixes all the path information of oblique lines received to a 45-degree oblique line and thereafter passes it to a line-drawing processing section (7).

Abstract: An input display device, including: a display area that displays a plurality of input keys; and a display controller that controls display of the plurality of input keys displayed in the display area. The display controller includes: a combination data creating portion that creates combination data of a first input key and a second input key which has been selected next to the first input key; a storage portion that stores the combination data in a memory; a candidate key extracting portion that extracts the second input key from the memory on the basis of the combination data stored in the memory when the first input key displayed on the display area is selected; and a display portion that allows the display area to display the second input key extracted by the candidate key extracting portion as a candidate which is to be selected next.
