An object of the invention is to display an image having the feeling close to that of a knitted fabric actually knitted with a fuzzy knitting yarn. At least part of knitting yarn image data (1) on a knitting yarn with much fuzz (2) is divided into certain lengths in a length direction in which the knitting yarn image data (1) extends, and is divided into a mesh (5) in an intermediate yarn main frame region and meshes (3, 4) in fuzz regions on both sides thereof in a width direction. Each of the meshes (3, 4, 5) is deformed in accordance with a stitch loop (6) constituting the knitted fabric to form deformed meshes (7, 8) in the fuzz regions and a deformed mesh (9) in the yarn main frame region. In this deformation, the ratio of the deformed meshes (7, 8) in the fuzz regions to the meshes (3, 4) in the fuzz regions is set smaller than the ratio of the deformed mesh (9) in the yarn main frame region to the mesh (5) in the yarn main frame region.

An object of the invention is to display an image giving a feeling close to the feeling of a knitted fabric actually knitted with a knitting yarn. Linear knitting yarn image data 1 is divided into a plurality of meshes 2. The mesh 2 is made to match a transformed mesh 3 transformed along the shape of a knitting stitch loop 4. The knitting yarn image data 1 is subjected to an image drawing processing by a mesh transforming technique to create the image of the knitting stitch loop 4. A lower section 4a and an upper section 4b are defined in a portion where the knitting stitch loops 4 are overlapped, the portion where the knitting stitch loops are overlapped is synthesized as a knitted fabric 6, and displayed. Fluffiness or the like is also reproduced, and consequently the feeling like that of an actual knitted fabric can be given.

An object of the invention is to quickly display a simulation image of knitting stitches approximate to an actually knitted fabric. When an image is present in the position of the knitting stitches 12, 13 corresponding between an upper layer 1 and a lower layer 2, the images of knitting stitches for pattern 11 or transformed knitting stitches 12, 13 in the upper layer 1 having the highest priority are displayed. In each layer, it is possible to perform an editing operation of selecting combinations of knitting stitches previously registered in a form of module from a library and changing the position and the shape of the image of the knitting stitches. The knitting stitches in the periphery of the knitting stitch for a pattern 11 are substituted for the transformed knitting stitches 12, 13 reflecting the influence of the making of the knitting stitch for pattern. Image data on basic knitting stitches 10, the knitting stitch for a pattern 11, and transformed knitting stitches 12, 13 is created utilizing the images of actual knitted fabrics or computer graphics and is stored. By combining the stored image data, a simulation image of knitting stitches like that of an actually knitted fabric can be quickly displayed.

The present invention discloses a method of manufacturing knitted fabrics, more particularly a method of skillfully transferring a painting artwork onto a knitted fabrics to show the artistic verve of the painting. The manufacturing method includes the steps of: inputting an original drawing into a computer for digitization; editing and designing the digitized original drawing on a knitted fabric; outputting a knitting square plot after a graphic software performs a color processing; introducing graphic file information analyzed and processed by a knitting software to a knitting machine; and operators following a lamp signal of the knitting machine and the knitting square plot to knit to shape a knit piece, so as to complete a fashioned fine-art knitted fabric.
