echo "example: ./slice.sh Sunset.jpg 800 600 16 16"
exit
else
for (( x = 1; x <= COLS; x++ ))
do
for (( y = 1 ; y <= ROWS; y++ ))
do
let CROP_X = `expr $IMAGE_W-IMAGE_W/$x`
let CROP_Y = `expr $IMAGE_H-IMAGE_H/$y`
let CROP_W = `expr $IMAGE_W/$ROWS`
let CROP_H = `expr $IMAGE_H/$COLS`
echo -n "crop ${CROP_W}x${CROP_H}+${CROP_X}+${CROP_Y} result: [${x},${y}]_$IMAGE"
echo ""
convert $IMAGE -crop ${CROP_W}x${CROP_H}+${CROP_X}+${CROP_Y} [${x},${y}]_$IMAGE
