Claim 6:
7. The applique data management apparatus according to claim 5, further comprising:
an operation interface; and
a memory configured to store a threshold value indicating the particular distance,
wherein the controller is configured to:
acquires the threshold value stored in the memory;
receive a change of the threshold value via the operation interface and update the threshold value in the memory;
expand or contract an inner contour line in the inner contour image based on the threshold value by expansion-contraction processing;
expand or contract an outer contour line in the outer contour image based on the threshold value by the expansion-contraction processing;
in response to determining that the pixel value of at least one pixel indicating the inner contour image and the pixel value of at least one pixel indicating the outer contour image at the same coordinate position match and have a value representing the contour, determine that the inner stitch and the outer stitch are arranged at positions closer to each other than the particular distance; and
in response to determining that, for all pixels in the contour image, the pixel value of each pixel indicating the inner contour image and the pixel value of each pixel indicating the outer contour image at the same coordinate position do not match or do not have the value representing the contour, determine that the inner stitch and the outer stitch are not arranged at positions closer to each other than the particular distance.
