An image-printing device includes a reading unit, a sample characteristic amount extracting unit, an original characteristic amount extracting unit, an image converting unit, and a printing unit. The reading unit reads a sample image and an original image. The sample image has a sample characteristic amount indicating a characteristic of the sample image. The original image has an original characteristic amount indicating a characteristic of the original image. The sample characteristic amount extracting unit extracts the sample characteristic amount from the sample image. The original characteristic amount extracting unit extracts the original characteristic amount from the original image. The image converting unit converts the original image based on both the sample characteristic amount and the original characteristic amount. The printing unit prints the converted original image.

An image forming device for forming images based on a file configured of a first data area for storing raster data and a header for storing vector data. The image forming device includes a raster data image displaying function for forming images on a display screen based on the raster data; and a vector data displaying function for forming images on the display screen based on the vector data. With this construction, the image forming device can easily manipulate both vector data and raster data by combining both types of data in one file. The image forming device can rapidly combine both types of data in one image by using vector data in parts requiring high image quality and raster data in parts requiring high-speed drawing.

Image forming device for processing a file containing raster data and vector data

A RIP() calculates total line number of print data when converting original data to the print data. When a printer () is requested by the RIP to send a printed line number, the printer () detects the physical position of a print head () using a sensor () calculates a printed line number, and transmits the obtained printed line number to the RIP (). The RIP () notifies a user of progress of print operations based on the total line number and the received printed line number.

Print system capable of inform user of progress of print operations

A printer receives input data from an external apparatus and converts the received input data into print data. The print data is provided to a printing device for carrying out printing operations on the basis of the print data. A data transmitting device transmits the print data, converted from the received input data, to another printer.

Printing assembly and printing method for contemporaneous print jobs

A method and a device for transmitting print data from a computer to a print control device for controlling a printer, wherein a desired one of attribute data sets which accompany respective image data sets is replaceable by a new image data set in a data transmission mode of the computer, and the attribute data set accompanying the original image data set replaced by the new image data set is suitably changed according to the new image data set. The print data including the new image data set and the changed attribute data set are transmitted to the print control device. The print data may include direct image data such as bit map data, and non-direct image data which include indirect image data such as character data and graphic data, and print control data such as attribute data. When a file name of any direct image data stored in a memory is included in the non-direct image data, the direct image data are retrieved from the memory, and transmitted to the print control device such that the retrieved direct image data and the non-direct image data are not interspersed with each other.

A digital image processing device is provided with a plurality of image enlarging/reducing units for processing the digital original image data in manners different from one another and enlarging or reducing the original image with a desired magnification/reduction ratio value. The digital image processing device is further provided with a selection unit for selecting one of the plurality of image enlarging/reducing units in accordance with at least one of the desired magnification/reduction ratio value and information on the original image to thereby allow the selected one of the plurality of image enlarging/reducing units to process the digital original image data in the corresponding manner to thereby enlarge or reduce the original image with the desired magnification/reduction ratio value.

A print control apparatus for use with a printer for forming a print output based on command data generated by a computer. The print control apparatus includes a line segment data conversion unit for converting computer-generated command data to successive pieces of line segment data each having a position and a length in a raster direction, and a raster image data conversion unit for converting the line segment data to raster image data based on which printing is performed by the printer.

An apparatus for producing embroidery data which are used by a sewing machine to move a sewing needle and a work cloth relative to each other so as to form stitches filling a desired original pattern on the cloth, the embroidery data including sets of coordinate data each representing a stitch position where the needle penetrates the cloth, the apparatus including a first device specifying a plurality of first defining points defining a first curve including at least one first adjustable curve segment in series, and a plurality of second defining points defining a second curve including at least one second adjustable curve segment in series and cooperating with the first curve to approximate an outline of the original pattern; a second device establishing an embroidery area by connecting between each of both ends of the first curve and a corresponding one of both ends of the second curve, and producing first sets of coordinate data representing a plurality of first stitch positions including at least one position along the first curve, and second sets of coordinate data representing a plurality of second stitch positions including at least one position along the second curve; and a third device producing the embroidery data by using the first and second sets of coordinate data, so that the sewing machine forms embroidery stitches by alternately connecting with a sewing thread between the first stitch positions and the second stitch positions according to the embroidery data.

Embroidery data producing method and apparatus

A digital image processing device for enlarging an original image with high fidelity. To produce digital data representative of an enlarged image based on digital data representative of an original image, 2-by-2 enlarged image data is firstly produced, for example, through computation of approximate surface representative of density distribution of the original image approximate to a surface covering all density values. Based on the 2-by-2 enlarged image data, another approximate surface covering all density values of control points selected from the pixels constituting the 2-by-2 enlarged image. Then, a center portion of the thus obtained approximate surface is enlarged to a desired size and four center portions of such enlarged approximate surface are obtained while selecting the control points on one pixel shifted positions in row and column on the 2-by-2 enlarged data. The thus obtained four center portions are averaged, which gives the image data representative of the enlarged image.
