摘要： Methods and systems are presented for converting an image to a color-reduced image suitable for embroidery and having colors mapped only to available embroidery thread colors. Pixel color values in the image are snapped to a nearest color in a predetermined reduced set of colors that correspond to embroidery thread colors. The image is then color-reduced by iteratively identifying possible pairs of colors in the color-reduced image and merging at least one identified color pair based on color similarity and edge characteristics until the total number of colors in the color-reduced image is not greater than the predetermined maximum color count.

摘要： Rendering methods, systems, and computer-readable media for rendering a simulated embroidery design image based on an embroidery design are presented. Given an embroidery design comprising a plurality of stitch representations and a lighting angle for the simulated embroidery design image, embodiments process the stitch representations to determine a stitch length and lighting angle and select from a stitch image database a stitch image corresponding to the stitch length and lighting angle, and place the selected stitch on a rendering canvas in a position corresponding to the stitch position indicated by the stitch representation. When rendered, all of individual stitch image on the rendering canvas appear to be illuminated from the same direction.
