KXStitch!

Cstitch turns an image into a cross stitch pattern and allows you to edit the generated pattern. The final product is a pdf of the cross stitch pattern and a list of the colors in the pattern.

This tool allows you to make your own unique cross stitch scheme from custom image. You can resize and rotate image, reduce the number of colors, change image palette, make cross stitch design, preview it, save and print. Cross stitch design edition available: colors and icons changing, new color addition, color fill, design pixel draw, lines and half-stitches.

PCStitch is advanced, but it's perfect for any cross-stitcher.
