The disclosure presents an embroidery data processing device and a computer program product capable of creating a single unit of tree structure vector data by coupling plural pieces of independent tree structure vector data. A coupling node is added between nodes and of a tree structure vector data, and a vector data to for coupling nodes and, and a vector data to for coupling nodes and are created, and thereby a tree structure vector data is created. In a tree structure vector data, the node mutual direction is converted so that the node existing at the connecting position may be a root node, and a tree structure vector data is created, and this root node is coupled with the coupling node of the tree structure vector data, and a single tree structure vector data is created.

Embroidery data processing device and computer program product

The disclosure presents an embroidery data processing device and a computer program product capable of tearing off an elastic sheet easily after an item of embroidery has been sewn, thus enhancing working efficiency. A CPU extracts a contour line from needle drop points PN (N=1, 2, . . . , n) stored in embroidery data (Sto S). When the CPU judges that each needle drop point QN on the contour line is separated from an adjacent needle drop point Q (N+1) by more than a specified distance, the CPU forms needle drop points between adjacent needle drop points QN and, Q (N+1) separated from each other by more than a specified distance, reads out from a ROM tearing stitch data for forming a stitch of satin stitching different in stitch width in an inside direction of an embroidery region, and adds the tearing stitch data to the embroidery data so that a sewing sequence of stitches of satin stitching is ahead of a sewing sequence of stitches of the embroidery pattern main body in the embroidery region (Yes at Sto S).

The disclosure presents a quilting data processing apparatus and a program capable of displaying changes of fabric caused by a sewing line, and or easily displaying a visual image of a finished state of quilting. The CPU receives the fabric pattern of quilting, the thickness of fabric, the thickness of elastic material, and the sewing line of quilting, and, when the preview button is pressed, creates a basic mesh pattern, calculates the total deformation degree, deforms the basic mesh pattern sequentially along the sewing line to a deformation degree commensurate with the total deformation degree, and deforms each mesh adjacent to deformed meshes commensurately with the deformation degree, thereby creating a deformation mesh pattern (Sto S). Consequently, the CPU adheres to each mesh the fabric pattern displayed in a specified size in accordance with the deformation mesh pattern so as to create deformation fabric image data, overlaps the sewing line data to the upper side of the deformation fabric image data, and displays as a quilting pattern (Sto S).

Quilting data processing apparatus and computer program product

The invention presents an embroidery data processing device and a computer program product capable of easily forming images of finished state of applique even if the fabric for applique is a pattern fabric. A selected fabric image of fabric for applique is displayed, and when the user manipulates the mouse, and moves the cursor to a desired position of the fabric image, and clicks by a specified number of times, the applique pattern preliminarily inputted through the image scanner is displayed at the position of the cursor (Sto S). When the user clicks the preview button by the mouse, only the fabric image within the applique pattern is extracted, and an applique image is displayed, and an applique sewing stitch image is overlaid and displayed on the applique image (Sto S).

An embroidery data producing device is disclosed producing embroidery data on which an embroidery sewing machine forms an embroidery pattern along another pattern previously formed on cloth held by a cloth holding frame. The embroidery data producing device includes image data producing means for scanning the cloth held by the cloth holding frame to produce pattern image data corresponding to the pattern, and embroidery data producing means for producing embroidery data for forming an embroidery pattern on at least a part of the pattern on the basis of the pattern image data, the embroidery pattern having a size equal to that of the pattern.

An embroidery data producing device includes an area information input unit for inputting area information indicating first and second areas to be embroidered, at least a part of the second area being overlapped inside the first area, a first setting unit for setting a first stitch type for one of the first and second areas, a second setting unit for setting a second stitch type different from the first stitch type for the other area than the area set by the first setting unit, and an embroidery data producing unit for producing first and second embroidery data based on the stitch types set by the first and second setting unit, respectively, the first embroidery data being used to embroider the first area except for its part on which the second area is overlapped, the second embroidery data being produced to embroider the second area.

Embroidery data producing device and embroidery data producing control program

The disclosed apparatus and program stored on a computer readable medium for processing embroidery data make stitch data subdivisions into which the stitch data was divided, according to the size of partitions, and add partition position information corresponding to the position of stitch data subdivision in the stitch data to the stitch data subdivisions. If the size of an embroidery pattern which is embroidered by the embroidery data is greater than a predetermined workable area of sewing within the embroidery frame, the embroidery data is divided into subdivisions and where the embroidery data subdivisions is positioned in the whole embroidery design can be identified.

Apparatus and program stored on a computer readable medium for processing embroidery data

An embroidery data producing device includes an offset line producing device for producing data of an offset line obtained by offsetting an outline defining an embroidery area inside an embroidery area by a previously set offset width, based on data of the outline defining the embroidery area, a self-intersection or mutual intersection detecting device for detecting a self-intersection of the offset line produced by the offset line producing device or a mutual intersection of the offset line and the outline, and an offset line changing device for changing the offset line data produced by the offset line producing device upon detection of a self-intersection or mutual intersection by the self-intersection or mutual intersection detecting device so that the self-intersection or the mutual intersection is dissolved.
